CSS centering absolutely positioned elements

Windows : Internet Explorer 8.0+, Firefox 1.0+, Google Chrome, Opera 5.0+, Safari 3.1+, SeaMonkey 1.0+ [ 1 ].

Linux : Firefox 1.0+, Google Chrome / Chromium, Opera 5.0+, SeaMonkey 1.0+ [ 2 ], NetSurf 2.6+.

CSS horizontal centering of an absolutely positioned element. Example:

Image

HTML / XHTML. Code:

<div class="example">

<img src="image.jpg" alt="Image" />

</div>

CSS. Code:

.example {position: relative; left: 0px; top: 0px; height: 90px; width: 100%; float: left; padding: 10px; border: 1px #ccc solid; background: #fafafa; -moz-box-sizing: border-box; -webkit-box-sizing: border-box; -ms-box-sizing: border-box; box-sizing: border-box;}

.example img {position: absolute; left: 0px; right: 0px; margin: 0px auto; width: 68px;}

An absolutely positioned img is centered in the example. But this method of horizontal centering also works with other both inline and block absolutely positioned elements.

The width of an absolutely positioned element may also be in percent or other units.

CSS properties of a container (here it is .example), holding an element to be centered, may vary. The element's centering is achieved by styles applied to the element itself: .example img {position: absolute; left: 0px; right: 0px; margin: 0px auto;}.

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.

Windows console applications. Multimedia

 

MPlayer : FFmpeg Media players appeared long ago, but their heyday began with the mass spread of personal computers powerful enough to play video files. This coincided with the mass spread of operating systems and other software with graphical user interface. However, a program with a graphical user interface is dualistic in its nature: there is a code responsible for graphical user interface, for the appearance and there is a code - for performing the task the given application has been created for in the first place. Both code complexes consume system resources, their response time to user actions makes up certain amount of waiting time. And in cases or concepts when appearance is taken as less important - less important to the point of sparing or almost sparing to employ it - console applications, among others, appear. Moreover, the segmentation of the GUI and of the engine makes it easier to change the graphical user interface or perform complex automated operations. The scheme is implemented for media players for Windows as well. MPlayer, for instance, in its usual form is a console application, starting up quickly, having fast response to user actions, consuming system resources almost entirely for its immediate task. And on this basis if desired, one or another graphical interface may be added for creating, all in all, a new application. MPlayer - / home page / Console media player for Windows. Basis for SMPlayer and UMPlayer. There are versions for Linux, FreeBSD, NetBSD, OpenBSD, Apple Darwin, Mac OS X, QNX, OpenSolaris/Solaris, Irix, HP-UX, AIX, some other *nix system, BeOS, Syllable, AmigaOS, AROS, MorphOS, DOS, Windows.
