A '''CSS hack''' is a [[Computer programming|coding]] technique used to hide or show [[Cascading Style Sheets|CSS]] [[Markup language|markup]] depending on the [[Web browser|browser]], version number, or capabilities. Browsers have different interpretations of CSS behavior and different levels of support for the [[W3C]] [[World Wide Web Consortium#Standards|standards]]. 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.

{{Main|Conditional comment}}

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.
