IE conditional comments for XHTML
|
<br />Conditional comments are a feature unique to IE that can perform separate XHTML code processing on IE series products. Note that it is mainly for XHTML, not CSS. Conditional comments are very powerful and can be used to make true and false judgments, for example: Program Code <!--[if IE]>This content is only visible to IE<![endif]--> <!--[if IE 6.0]>This content is only visible to IE6.0<![endif]--> Conditional comments can be used by IE to determine the version of the browser and display the content if the conditions are met. IE5.0 to 7.0 all support the comment function, and the version number is accurate to 4 decimal places: Program Code <!--[if IE 6.1000]>This content is only visible in IE6.1<![endif]--> IE conditional comments also support the exclamation mark non-operation: Program Code <!--[if !IE 6.0]>This content is visible except for IE6.0 version<![endif]--> And it supports prefixes to determine higher or lower versions: Program Code <!--[if gt IE 5.0]>This content is only visible in IE5.0 and above<![endif]--> The gt here stands for greater than, which means versions above the current condition version, but not including the current version. There are several other prefixes: lt means less than the version below the current condition version, excluding the current version. gte means greeter than or equal to the current version and including the current version. lte means less than or equal to the current version and includes the current version. |
