Centering the content of a web page in the viewable area of a browser by means of CSS. A box to contain the whole content of the page is CSS centered horizontally and vertically: [ Open demo page ]

HTML / XHTML. Code:

<!DOCTYPE html>

<html>

<head>

<title>CSS horizontal and vertical centering - 2</title>

<link rel="stylesheet" type="text/css" href="css.css" />

</head>

<body>

<div class="spacer">&nbsp;</div>

<div class="wrapper">

<div class="pagecontent">&nbsp;</div>

</div>

</body>

</html>

CSS. Code:

html {height: 100%; margin: 0px;}

body height: 100%; margin: 0px;}

.spacer {position: relative; top: 0px; left: 0px; height: 50%; width: 100px; float: left; margin: 0px 0px -250px 0px; background: #999;}

.wrapper {position: relative; top: 0px; left: 0px; height: 500px; width: 100%; clear: both; background: #a3ddc4;}

.pagecontent {position: relative; top: 0px; left: 0px; height: 500px; width: 800px; margin: 0 auto; background: #ff6f6f;}

The .pagecontent box is for the page content. It must be of a fixed height and width in units like px's or em's - not in percents. Height and width may be larger than web browser viewable area, but here the more practical case is discussed - when the height and width of .pagecontent are smaller than those of the web browser viewable area.

The .pagecontent box is horizontally centered by its "margin: 0 auto".

.Wrapper creates a space where .pagecontent is centered horizontally. .Wrapper's width is 100% for centering at various web browser viewable area sizes. The height has to be equal to the one of .pagecontent.

.Spacer centers .wrapper with .pagecontent in it vertically inside browser viewable area. Its width may be any. The height is 50% - that places the top edge of .pagecontent vertically in the middle of the browser viewable area. The bottom margin of .spacer equal to half the .pagecontent height centers .pagecontent and its contents vertically in the web browser viewable area of a current height.

This method is reliable in all major modern web browsers. It also works in older browsers like Internet Explorer 6 or earlier versions of Maxthon. But the height of box for page content has to be assigned explicitly and if it is changed - the size of .spacer bottom margin must be changed accordingly as well. There is another way of CSS horizontal and vertical centering, with CSS code easier to maintain, even if not suitable for older web browsers: CSS horizontal and vertical centering - 1.

Screenshots in DOS

 

There are several programs for taking screenshots in DOS. SNARF, for instance. Using this application succeeded in taking screenshots in most of the cases. Also, the screenshots' quality (.BMP files) by SNARF results to be the highest among the programs tested: ScreenThief, VideoThief, FLIP, GRABBER, SNARF. Using SNARF with default settings is straightforward, but there is a shortcoming - SNARF always saves screenshots to the folder where the user is currently in. That could be inconvenient or unacceptable. And there is no obvious way to change it. But there is a roundabout option. The initial idea had been found on this page. The result based on it: 1. SNARF [ Download ] 2. Open SNARF.EXE in a text editor in text mode (not hex), find snarf000.bmp and replace it for s:scn000.bin 3. Create a batch file, S.BAT for example, where besides a string for starting SNARF.EXE will be a command assigning the path to the folder screenshots will be saved into to a virtual drive S: The folder and path may be any: C:\SOFT\SNARF.EXE SUBST S: C:\SCREENS\ 4. Start SNARF: S [or S.BAT] 5. To take a screenshot: Alt + S There will be two beeps. The first at the beginning and the second one as a sign the process has completed successfully. After the screenshots are taken, go to the folder where they are saved in and replace the file extensions from .BIN to .BMP SNARF - Freeware.

Text-based web browsers for Linux

There were several web browsers already, many of them ported gradually to Linux. Some text-based web browsers were in the first wave. After a while Linux became the main habitat of text-based browsers, where most of them are developed and used. Even if these text-based web browsers are mostly intended not just for Linux, but for various other *nix systems as well. And there are also their ports to plenty of other operating systems for most various platforms. Lynx - / home page / Text-based web browser.
