Alignment of tag content. How to align text to center, width, page edges in HTML? Heading in the middle of the html page

To select the desired input elements of type "checkbox", you can use the selector ‘: Checkbox’... Example:

where handler - a handler that is called when the change event occurs

Working with Callbacks in jQuery: Using a List of Callbacks

The jQuery Callbacks object allows you to create something like a list of callbacks that will be executed when you call the fire () service method. Moreover, when calling the fire () method, it is possible to pass some kind of argument that will be used by each callback function. How it works, we will now analyze a few examples.

We catch the loss of focus. The blur () method in jQuery

The blur () method in jQuery allows you to assign a handler to a specific element on a page that will be called as soon as focus is lost from that element. Initially, this event was mainly related to form elements - input tags, however latest versions browsers are capable of handling this event for almost all kinds of DOM elements.

Inserting content before the content of the selected object. The before () method in jQuery

The before () method in jQuery allows you to insert specific content or objects in front of the content of each of many specified objects.
The method syntax is simple:

1 .before (content,)

Second variation:

1 .before (function)

jQuery. Attr () method. How to get or add an attribute to an element

jQuery makes it very easy to access the attributes of the desired element by fetching its value or, conversely, setting and changing. The attr () method is used for such manipulations.

The .appendTo () method in jQuery. Adding content to the end of elements

The appendTo () method essentially performs the same task as the append () method. The difference, by and large, is only in the syntax. If for append () we specify the desired selector, adding this method to it, where in parentheses we indicate what exactly needs to be added to the end of the contents of the specified object, then for appendTo () what needs to be added is no longer in parentheses as a method parameter, but just before the method itself as the object on which appendTo () is called. The difference will be better understood in the following example.

JQuery .animate () method: animating images, text, and whatever

The .animate () method allows you to create animation effects using the css properties of the objects themselves. The method has two variations with a different number of parameters passed

Converting videos with Movavi

Recently, in order to make good use of the time taken on the way to and from work, I have been trying to download more useful videos to my phone in advance. The phone is on Android, and just recently ran into a problem when the smartphone refused to play AVI videos for some reason. Whether the player is weak, or the specifics of the operating system - I don't know. However, I didn't have to solve the problem for a long time: I found a fairly functional video converter on the network, which is able not only to convert it from one format to another, but also to prepare a file taking into account the characteristics of your device. Here a brief description ofhow to use this wonderful program.

This lesson focuses on HTML attributes and headings, which are essential elements of any HTML document... This is why it is so important to be familiar with this issue. This lesson explains what an attribute is and provides examples of working with attributes. The lesson also discusses the headers used in HTML, provides examples of headers.

Attributes in HTML

What is an attribute? An attribute refers to a parameter that provides tags with specific information. There can be a lot of these parameters. For example, using attributes, we can align the text of a paragraph in width, set the style and size of the font, set the required indents, etc. Attributes are written inside tags, followed by an equal sign, then in double quotes attribute values \u200b\u200bare specified. Separate attributes from each other with semicolons.

Examples of working with attributes

Let's consider working with attributes using examples. The simplest example - let's take a paragraph tag

With the "align" attribute. Let's write:

Example of aligning a paragraph to the left

The "align" attribute tells the browser to align the given paragraph to the left of the screen.

Attributes can also be applied to a paragraph tag:

  • align \u003d "center" - alignment to the center of the screen;
  • align \u003d "right" - right alignment;
  • align \u003d "justify" - alignment of the text to the width of the screen.

Now let's complicate the task - create HTML page using several different attributes. An example of such a page would have the following code:

Example page with attributes in HTML

Attributes in HTML

The "bgcolor" color attribute allows us to set the background color of the page. The "center" and "justify" attributes align the text within itself, center and width, respectively.

Headings in HTML

with index. There are only six such indexes - from 1 to 6, they indicate the size of the header (

is the largest title

- the smallest). As an example, let's create a web page that has multiple headers. The code for this page will look like this:

Example page with attributes and titles in HTML

Attributes in HTML

What is an attribute? An attribute refers to a parameter that provides tags with specific information. There can be an unlimited number of these parameters.

Headings in HTML

In order to create a title on the page, a special tag is used with index. There are only six such indexes - from 1 to 6, they indicate the size of the header ...

In this example, we have two headings - the first level heading here has no attributes, the second level heading has a center alignment attribute. After the headings, there are paragraphs, which also have their own attributes.

This is how you work with attributes and titles in HTML. There is nothing complicated here. You should definitely practice using your own examples in order to consolidate the information received in this lesson.

As I promised earlier, in this tutorial you will learn how you can horizontally align the content of any HTML tag on a page without using the deprecated align attribute. As you might have guessed, we will be using styles (CSS) again, or rather our favorite style attribute.

So, to align the content of an HTML element, you need to set the style attribute to one of the following values:

  • text-align: center - Align each line to the center of an element, such as a paragraph.
  • text-align: left - Each line is pressed close to the left side of the element (this is the default).
  • text-align: right - Each line is pressed against the right side.
  • text-align: justify - Alignment immediately to the left and right sides of the element. Will explain. Typically, an element, such as a paragraph, has one side of the text always straight, and the other - "torn", since the lengths of the lines are slightly different. And when we use the value text-align: justify, then each line is evenly spaced across the width. If necessary, the browser adds additional spaces between words, and the first and last word of the line are always pressed against the corresponding sides, so a block is obtained even on both sides.

Example of aligning tag content

Aligning tag content

Center heading.

Center paragraph.

Result in the browser

Center heading.

The paragraph text is pressed to the right.

Center paragraph.

In general, horizontal alignment only applies to block tags and table cells (we'll talk about them later). Although, on the other hand, even if you try, you won't be able to apply it to inline. Why? Remember we recently found out that the width of an inline element is equal to its content? Accordingly, it turns out that this very content will simply have nowhere to align and the browser will simply ignore your "art". :)

Homework.

  1. Create a title for the article, two sections and one subsection in the first section. And let the article title be centered on the page.
  2. Set the entire page to Arial and all headings to Times and use italics.
  3. Set the color of the article title text to # FF6600, sections # 6600FF, and leave the subsection unchanged.
  4. Write one paragraph under each heading, and each paragraph must be at least three lines long when viewed in a browser.
  5. Align the second paragraph to the center, the third to the right, and the fourth to both.

Many text elements on a web page need to be centered. Most often headings. Let's take a look at how to do center alignment in css.

The text-align property

The text-align property is responsible for this, and it has four values:

  • Left - aligns the text to the left of the element in which it is located
  • Right - right-aligned, but the direction of the text remains unchanged
  • Center - in the center. That is what we need. You don't need to set any additional parameters - the browser itself will place the text exactly in the center at different screen resolutions
  • Justify - Justify, when words in each line are stretched to fill its entire width

For example, we have arbitrary text with a title:

Heading

To center our heading (h1), we need to write this:

H1 (
Text-align: center
}

The property aligns not only normal text, but all inline elements. For example, the default image is an inline element, so this rule will also affect it.

Text-align does not act like a float property. If text-align is applied to a block element with text, then the block will not lose its behavior. It will be the text in it that will be pressed, and not the block itself. Note that this differs from the float property, which sends the entire element to the right or left.

We continue to study HTML. In this tutorial we will look at HTML page headers, what headers are, how to use them correctly, and when they can be used. We will also analyze the paragraphs so that you can already fill your page with text, but, most importantly, do it correctly.

If you have not studied the first article, then you can find it here:

  • Lesson 1. What is HTML?

Theory and Practice - HTML Page Paragraphs and Headings

Today we are going to talk about paragraphs and headings. Let's start simple - with paragraphs and where they apply.

Paragraphs per page

I will now give an example code in which the paragraph tag will be present.

You already remember the basic structure from the first lesson. There they took apart the basics and looked at what HTML is. Therefore, we will focus on what is between the tags .


When you write any text on the page, be it just a paragraph or a small explanatory line under the image, you need to put this text inside the tag.

In subsequent lessons you will see the process of formatting these paragraphs. Now you should understand that you cannot place a tag on a page without any tag. Because in the future it will be difficult to apply any individual styles specifically for this section of the text.

Try to write a few paragraphs. Put some paragraphs in a tag, and leave some without it. And you will immediately see the difference. Because if you write a paragraph inside this tag, then it will immediately appear indented. Now let's move on to the HTML page headers.

HTML headers on the page

The HTML document contains semantics. I'm not talking about HTML5 technology and its new tags. Here we will just analyze the most basic ones so that you can quickly master the basics of HTML. Semantics means that you don't need to create headings, paragraphs, tables, and so on using the same tag. This can be done, but HTML technology is more varied and appropriate tags are provided for different situations. And you just need to master the basic tags to work freely with HTML code.

I wrote this little introduction to the fact that for paragraphs it is necessary to use a tag already known to you. But for headings, tags are used that begin with the English letter "H".

Here is the entire list of headers that you can use:

Some of these tags are used much more frequently. These are tags like h1, h2 or h3. If someone is already familiar with CSS, then it will be understood that the HTML heading of the h3 page can be styled in such a way that it looks similar to h1 or h2. But the meanings they carry, at least for SEO optimization, are radically different. As a rule, these numbers, inside tags, should be understood as the level of importance of this or that HTML heading. Therefore, it is necessary to study these elements very carefully and then the search engines will notice your articles.

Until we get to CSS, you'll see the heading styles that are set by default in browsers. If you insert one by one these tags and write some text inside, you will see the following:

It is also important for search engines to use headings on the page. There are certain rules that you can read in our book - PDF book on website promotion.

After we have studied everything, we immediately go into the code and try to write everything with our own hands. This is the fastest way to learn any programming language. But HTML technology is much lighter than any programming language, so everyone can figure it out. This way you will remember the tags better.

How to make a table in HTML

Any table contains rows and columns. They, in turn, can contain text and images.

To add a table to the page, use the tag

... This is the main and main container in which table elements (rows and columns) are placed. And this container needs to be closed -
.

Rows and columns are defined using tags and , while instead of you can safely use ... The difference from is that the browser displays the text in the cell as bold and also aligns it to the center of the cell - i.e. can be used in table headers without additional formatting. Otherwise, there is no difference between them, you can use any.


Table rows ( ) must be placed strictly between

... And the table columns ( ), in turn, are placed strictly between tags .

Let's practically create a table that has one row and four columns. We need to mark the beginning of the table (

), beginning of line ( ), four cells ( ), end of table (
), end of line (
).

Result:

Now let's use the tag to never come back to it.

Result:

I set the table width to 400 and as you can see, the first and third cells are bold and centered. The rest are aligned to the left. I recommend that you always devote enough time to formatting your code so you don't get confused about it. In a small table, this may not play a big role, but in a large ...

Let's talk a little more about the width since I mentioned it. The width of the table is set by the width attribute, the height is set by the height. You can change in this way not only the width and height of the table, but also the size of the cells (they must all fit into the table, otherwise the browser will not understand what you want from it).


These values \u200b\u200b(width and height) are set in pixels, percent. You can leave it like that, do not write anything, the browser will think that you were too lazy to write "px" and consider the number as pixels.

Well, if you want to align the contents of one or more table cells, use the align attribute with the values \u200b\u200bleft, center, right. This is horizontal alignment, but there is also vertical alignment and it has its own separate attribute - valign, which can take on values: baseline (vertical alignment exactly on the baseline), bottom (on the bottom edge), middle (cell values \u200b\u200bwill be aligned vertically in the middle), top (top). By default, browsers align cells to the center (middle).

Increase the frame (borders) of the table and change its color

You may have noticed that I have already shown you how you can work with the border and width of a table. In general, by default, tables are always displayed in the browser without a frame, which is not always convenient. That's why:

Agree, somehow not very much. But this is not a problem for those already familiar with the HTML border attribute, which I used in the examples at the beginning of the post.

We add only 1 attribute and it gets better:


It's like Excel! Imagine that there would be no division of cells with lines (grid)? Well, the same horror. But what happens if we set the border equal to 10.

As you can see, border only affects the outer border and border of the table, changing the width of the outer border, and leaving the borders between table cells the same.

Let's change the color of this border, because there is also an attribute for this - bordercolor. Let's set its value equal to "d3d3d3". Result:

How to indent a table

Indents in the table are also needed to improve readability, as well as cell borders. We need the "cellspacing" attribute to create the padding. I will continue to work with our 4x4 table with this attribute applied to it. I will update the code for you (I only include one line so as not to clutter up the post):

Result:

These were the indents on the outside of the cells. But there is a similar attribute for setting the indents inside the cells - cellpadding, now I will also make it equal to 10 and you will see how the distance from the contents of the cell to its borders increased (I had to make the number of cells smaller so that the table does not grow excessively). The code:

Result:



Now let's remove "cellspacing" and leave only "cellpadding". Result:

So we figured out how to create and manage indents in the table. Excellent! If you are interested in how to do a line break, then it is written about it here.

How to correctly combine cells in a table

There are special attributes for joining cells in your table as well. These are "colspan" and "rowspan". The first (colspan) concatenates cells by columns (horizontally), the second (rowspan) - by rows or vertically. Let's combine something in our table.

Here carefully! When combining cells, you need to reduce their number by the number (minus one) that you write in the attribute parameters. If you create a table in HTML, merge cells without deleting unnecessary ones, then the site will go. We combine two - delete one. Combine three - delete two. Etc.


When merging cells in columns or columns, one cell must be deleted! And do this as many times as you merge cells. Now I will show you with an example.

When merging cells in columns or columns, one cell must be deleted! And do this as many times as you merge cells.

Now I will show you with an example. Here is our current table:

Let's merge the cells numbered “1 and 2”, “5 and 9”, “4, 8, 12”, “6 and 7”. Look how cool it turned out, I myself did not expect!

The principle of unification is as follows.

When horizontally merging cells number 1 and 2, you need to write "colspan \u003d" 2 ″ "in the first, place the contents of the second in the first (we are merging) and delete the second cell (or hide it from HTML as I did - I'll show it later.)

When vertically merging cells numbers 4, 8, 12, you need to write "rowspan \u003d" 2 ″ "in the first cell (number 4), and delete the contents of the rest after placing them in the merged cell.

Here's the code I got. I've hidden the cells for clarity (to make it clearer for you), but you can delete them.

I hope I explained it clearly and gave a good example.

How to make a table title

To set a title for the table - use tags after the beginning of the table (

), but before the start of the tag ... Here's what happens:

Well, a little HTML hack for those who need to place the table header under the table itself. Use the align attribute with a bottom value like this:

And then the table heading will move under the table.

So, we've covered almost everything, except for ... Background!

How to make a beautiful background for a cell or the entire table

HTML allows you to set the color not only for the entire background of the table, but also for each individual cell (if there is such a need). Sets the background color of a table or cell to the "bgcolor" attribute.

Let me first set the background for the entire table. This will be the color "" lightgreen "" (or in general, you can set it like this - "" # 90EE90 "" "). This is how my table starts now:

Result:

Wow, the background color of the cells is now very lightgreen. Now I will color one of the table cells back to white, assigning it the same attribute, only with a different color:

Tada! Result:



In my opinion, cool! If I participated in the creative spreadsheet competition (or teaching HTML preschoolers), I would definitely win.

I also wanted to write how to insert a picture as a table background in HTML, but I already mentioned this in my other article at the link above.

Good luck and success in learning HTML.

Layout and center alignment of site pages is a creative business and often causes difficulties for beginners. So let's see how to do it. Let's say we want to make a page with the following structure:

Our page consists of four blocks: header, menu, content and footer. To align the center of the page, we will place these four blocks in one main block (main): Using this structure as an example, we will consider several options.

Layout and centering of the rubber site

When making up a rubber site, the main unit of measurement used is -%, because the site should stretch in width and take up all the free space.

Therefore, the width of the "header" and "footer" blocks will be 100% of the screen width. Let the width of the "menu" block be 30%, and the "content" block should be located next to the "menu" block, i.e. it must have a left margin (margin-left) with a width equal to the width of the "menu" block, i.e. thirty%.

To make the "menu" and "content" blocks side by side, let's make the "menu" block float and press it to the left. We will also set the background colors for our blocks. Now let's write it all down to the stylesheet (on the style.css page)

The height of the blocks was set conditionally so that the result was visible. Take a look at our page in a browser:

If you resize the browser window, then the width of all blocks will change. This is not always convenient, since when the menu block is stretched, an empty space appears. Therefore, more often the width of the "menu" block is made fixed, let's do so too. To do this, we will replace the values \u200b\u200bof the corresponding properties in the style sheet: Now our page stretches more naturally. With fluid layouts, the pages take up the full width of the screen, so no center alignment is required.

But if you want, you can make it so that your page has equal indents to the left and right of the screen. To do this, we need to add a style to the "main" block, which is a container for all other blocks: Now our page looks like this:

Site layout and centering, fixed width

In this case, we will have to set fixed sizes for our blocks: Now our page is pinned to the left edge of the screen.

In this case, alignment in the center of the site pages can be done as follows. Let's remember that our page has a “body” tag, which can also be given a width and some margins.

Let's do this: set the “body” tag to 800 pixels wide (just like the “main” block) and a padding-left of 50%. Then the entire content of the "main" block will be displayed on the right side of the screen (ie from the middle to the right):

In order for our “main” block to be in the middle of the screen, we need its middle to coincide with the middle of the “body” tag. Those. it is necessary to shift the "main" block to the left by half its size. The width of the "main" block is 800 pixels, so you need to set the "margin-left: -400px" property to it. Yes, this property can take negative values, then the left margin is reduced (i.e., shifted to the left). And this is exactly what we need.

Now the style sheet looks like this: And our page in the browser is exactly in the middle:

We considered two options for aligning the center of the site pages, in fact, they are not a dogma. You can experiment and come up with your own version, just test it in different browsers. Unfortunately, what renders well in FireFox or Opera can be completely incomprehensible in IE and vice versa. And this must be remembered.

Good luck in your creative quest!
