Css hacks for different browsers

A CSS filter is a coding technique used to hide or

show CSS markup depending on the browser, version

number, or capabilities. Browsers have different

interpretations of CSS behavior and different levels of

support for the W3C standards. CSS filters are

sometimes used to achieve consistent layout

The easiest way to target IE is with conditional comments. There is a

robust syntax that Microsoft has created to allow authors to do this. Here

are two alternatives to parser CSS hacks only for IE:

The first hack targets only Firefox 1 and 2 by using the body:empty hack. The

second hack, which is quite clever target all versions of Firefox by using the

proprietary extension -moz. -moz combined with the -document url-prefix()

which by the way is used by Firefox Addon creators targets Firefox and

Firefox alone. By using proprietary extensions to CSS, as hacks, usually

means the most surefire way to target individual browsers without having to

worry about another browser possibly parsing the CSS.

/* Firefox 1 - 2 */
body:empty #firefox12
{
color:blue;
}

/* Firefox */
@-moz-document url-prefix()
{
#firefox { color:blue; }
}

The Chrome CSS hack works similar to the Safari hack. By using the -webkit

prefix we can target Chrome and Safari both as the both browsers have

similar features.

/* Chrome and safari */

body:nth-of-type(1) .chrome{
color:#ff0000;
}
OR
/* Chrome and safari */
@media screen and (-webkit-
min-device-pixel-ratio:0)
{
#safari { color:blue; }
}

The Safari CSS hack works similar to the Firefox hack because it uses a

Safari proprietary extension to CSS. By using the -webkit prefix we can

target Safari and only Safari.

/* Safari */
@media screen and (-webkit-
min-device-pixel-ratio:0)
{
#safari { color:blue; }
}
OR
body:first-of-type(1) .safari{
color:#ff0000;
}

The Opera CSS hack works because of negation in CSS. This targets

ALL browsers that support -min-device-pixel-ratio that aren't -webkit. It

will only be a matter of time before Firefox supports this and this hack

will then most likely apply to Firefox as well.

/* Opera */
@media all and (-webkit-min-
device-pixel-ratio:10000), not
all and (-webkit-min-device-
pixel-ratio:0)
{
head~body #opera {
color:blue; }
}

CSS Hacks: different kinds

Conditional comments are conditional statements interpreted by
Microsoft Internet Explorer in HTML source code. Conditional
comments can be used as a CSS hack by including links to

Conditional stylesheets based on the layout engine.

CSS browser prefixes are a way for browser makers to add
support for new CSS features in a sort of testing and
experimentation period. Browser prefixes are used to add new

Browser features that may not be part of a formal specification and to
implement features in a specification that hasn’t been finalized.
