CSS. Target Firefox only

Windows : Firefox 1.5+ [ 1 ] [ 2 ].

Linux : Firefox 1.5+ [ 3 ].

CSS targeting Firefox web browser only:

This text is red in Firefox


<p>This text is red in Firefox</p>

CSS. Code:

@-moz-document url-prefix() {p {color: #f00;}}

Unlike the method of styling elements for Opera browser only, it is essentially a hack - since the rule originally is intended for a different purpose. But lack of support in browsers other than Firefox allows to isolate code for use by Firefox web browser only.

[ 1 ]

Other browsers with Gecko web browser engine, like SeaMonkey 1.0+ or older Netscape 9.0, also support the hack.

[ 2 ]

Various versions of Internet Explorer, Google Chrome, Opera, Safari react to the hack as they are meant to - these browsers ignore the whole code of the Firefox specific hack.

There is also one more browser where text gets red - ELinks, an advanced text-based web browser with some support for CSS.

CSS centering absolutely positioned elements


CSS horizontal centering of an absolutely positioned element. Example: 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;}.
