CSS centering <hr />, if its width is less than 100%. Horizontal centering. Example:


HTML / XHTML. Code:

<hr />

CSS. Code:

hr {width: 50%; margin: 0 25% 0 25%;}

/* Extra CSS, just styling the look: */

hr {height: 1px; float: left; border: 0px; color: #f00; background: #f00;}

Note: mostly it works both with float: left and float: none. But float: left makes it for sure.

CSS horizontal and vertical centering - 1

 

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".

Float bottom

 

There is no "float: bottom" in CSS, but there is a way to achieve it by some other means.
