A CSS hack is a coding technique used to hide or show CSSmarkup depending on the browser, version number, or capabilities. Browsers have different interpretations of CSS behavior and different levels of support for the W3Cstandards. CSS hacks are sometimes used to achieve consistent layout appearance in multiple browsers that do not have compatible rendering. Most of these hacks do not work in modern versions of the browsers, and other techniques, such as feature support detection, have become more prevalent.

May 08, 2007  Mac OS users only account for 3.89% of site visits 1 and 1.7% of the site visits are on Safari, 2 so 2.19% of the population is on a mac and surfing the web with something other than Safari. In otherwords, I can’t find the stats now on IE5 mac usage, but it is likely a large chunk of the 2.19% of the population that is using a mac, but not.

If you wish to target only Webkit browsers on the Mac (Safari and Chrome), you can couple this tip with webkit’s proprietary media query as follows: @media screen and (-webkit-min-device-pixel-ratio:0.

Invalid or non-compliant CSS[edit]

Due to quirks in the interpretation of CSS by various browsers, most CSS hacks involve writing invalid CSS rules that are interpreted only by specific browsers, or relying on bugs in specific browsers. An example of this is prefixing rules with an underscore (as in _width) to target Internet Explorer 6—other browsers will ignore the line, allowing it to be used to write code specific to one browser.

Conditional comments[edit]

Safari Specific Css

Prior to version 10, Internet Explorer supported a special comment syntax that would allow blocks of HTML to be read only by specific versions of the browser. These comments are mostly used to provide specific CSS and JavaScript workarounds to older versions of the browser. No other browsers interpreted these comments or offered similar functionality.

The following are examples of the different syntax for these comments.

Criticism[edit]

Hiding code using hacks often leads to pages being incorrectly displayed when browsers are updated. These hacks can lead to unexpected behavior in newer browsers that may interpret them differently than their predecessors. Since Internet Explorer 6 and 7 have fallen out of use, CSS hacks have declined as well. Modern methods of feature targeting are less fragile and error-prone.

Alternatives[edit]

Browser prefixes[edit]

Each of the most popular browser rendering engines has its own vendor-specific prefix for experimental properties. However, due to the proliferation of these properties in live code, the browser vendors have begun to move away from this in favor of user-controlled feature flags.^[1]

List of prefixes[edit]

The following is a list of prefixes from various layout engines:

Limitations[edit]

Vendor prefixes were designed for features that were under development, meaning that the syntax may not even be final. Also, adding a rule for each browser's implementation of a function does not scale well when you want to support many browsers. Consequently, the major browser vendors are moving away from vendor prefixes in favor of other methods such as @supports feature queries.

Feature detection[edit]

JavaScript feature detection[edit]

Multiple JavaScript libraries exist to detect what features are available in a particular browser so that CSS rules can be written to target them. Libraries such as Modernizr add classes to the html element, allowing for CSS rules such as .cssgradients.header.

@supports[edit]

A new feature known as feature queries was introduced in CSS3, allowing the detection of specific functionality within the CSS (without requiring the use of a JavaScript library for feature detection). This new directive can be used to check for the support or lack of support for a specific feature, and checks can be combined with and, or, and not. Obviously, @supports rules will only work on browsers that support @supports.

JavaScript polyfills[edit]

While JavaScript feature detection and @supports rules can help to target browsers that require fallback functionality, they will not address bugs in specific browsers or enable that advanced functionality. Polyfills, scripts that make behavior consistent across all browsers, can be used to add support for new CSS rules (for example, media queries in IE 8) as well as fix bugs in specific browsers. Since polyfills add or fix functionality in browsers that do not have it, they serve a different purpose than feature queries, but can be used in combination with them.
