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 - 1</title>

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

</head>

<body>

<div class="all">

<div class="wrapper">

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

</div>

</div>

</body>

</html>

CSS. Code:

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

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

.all {position: relative; left: 0px; top: 0px; height: 100%; width: 100%; float: left; display: table;}

.wrapper {position: relative; left: 0px; top: 0px; height: auto; width: 100%; display: table-cell; vertical-align: middle;}

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

The .pagecontent box is for the page content. It may be of height assigned explicitly or just "height: auto". Unlike CSS horizontal and vertical centering - 2, here percents may also be used as CSS units; not just px's or em's. 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".

.All with its CSS properties makes the whole web browser viewable area into a CSS table.

CSS properties makes .wrapper into the cell of this CSS table. The content of this CSS table cell - the .pagecontent box with everything inside it - is vertically centered in the viewable area of a browser by "vertical-align: middle".

Nowadays file managers can, all in all, the same and in general the same way, but text-based file managers are more responsive to user actions.

Pure CSS responsive square

 

Responsive CSS square. No JavaScript / jQuery. Example:   HTML / XHTML. Code: <div class="square">&nbsp;</div> CSS. Code: .square {width: 10%; height: 0; padding-bottom: 10%;} /* Extra CSS, just styling the look: */ .square {background: #fd0;} Width: 10% makes the .square div to be 10% of the parent element's width. Height: 0 eliminates any height the element may have, letting padding-bottom: 10% to make it exactly equal to the width. So each time the width of the parent container is changed, the element's size gets recalculated. Based on the concept - CSS grid with responsive square cells: Square cell 1 Square cell 2 Square cell 3 Square cell 4 Square cell 5 Square cell 6 Square cell 7 Square cell 8 [ 1 ] As well as Netscape 6.01+, Mozilla 0.6+.
