Horizontal and vertical alignment of elements. Align boxes to the center in CSS Command to align to the middle in html
It would seem that there is nothing difficult to set an image or text in the center of the browser window. We use the CENTER tag and everything falls into place where we intended. However, not all so simple. There are three ways to center alignment, each of which has its own characteristics and differences in different browsers.
One of the simplest and most convenient tags - CENTER is designed to align a block of text. This tag can also be used to center figures and tables. The exception is the elements
or
for which the alignment is set by the properties of the IMG tag. Thus, if we place an element
inside the CENTER tag, the picture will be right-aligned.
Example 4.1. Centering with the CENTER tag
This text will be aligned to the center of the browser window, and the underlying
drawing on the right side.
Formally, CENTER should only be used as a parameter to other block tags (P, PRE, and others). However, in the Netscape Navigator 2.0 browser, CENTER was introduced as a standalone tag. This addition was intended to remove the extra vertical padding that appears when using block tags. If instead of the CENTER tag the text is placed inside a paragraph (
) , an additional vertical padding appears between the horizontal line and this text.
CENTER is not part of the HTML specification. In "official" HTML formatting, such as text alignment should be done via tag attributes (for example,

In order to take screenshots in DOS, there are several programs. For example, SNARF. With the use of this application, it was possible to take screenshots in the largest number of cases. Also, the quality of screenshots (.BMP files) made by SNARF is the best among the tested programs: ScreenThief, VideoThief, FLIP, GRABBER, SNARF. Using SNARF with the default settings is simple, but there is a drawback - SNARF always saves the screenshot to the folder where the user is currently located. Which may be inconvenient or unacceptable. And there is no obvious way to change that. However, there is a workaround. The original idea was found at this link. On the basis of which the following happened: 1. SNARF [ Download ] 2. Using text editor open the SNARF.EXE file in text mode, find snarf000.bmp and change it to s:scn000.bin folder where screenshots will be saved when SNARF is running.

The first at the beginning and the second as a sign of the successful completion of the process. After the screenshots are taken, you need to go to the folder where they are saved and change the file extension from .BIN to .BMP SNARF - Freeware.

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

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 by adding this method to it, where we indicate in brackets 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 brackets as a method parameter, but just before the method itself as the object on which appendTo() is called. The difference will be better understood with the following example.

Video conversion with Movavi
Recently, in order to make good use of the time taken by the road to and from work, I try to upload more useful videos to my phone in advance.

Here is a brief description of how to use this wonderful program.
