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.

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.

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

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:
