How to distinguish IE from non-IE in html condition annotations
<! -- [If! IE]>
....
<! [Endif] -->
The HTML annotation format is that IE has made some extensions to HTML annotations so that it can support conditional judgment expressions. How can I make static HTML code
Similar to programming languages, the expressions here also support operators such as greater than (gt), less than (lt), and non-equal operators, conditional annotation is a unique extension of annotation in IE5.0 and later versions. It is not supported by other browsers. [If IE] determines whether IE [if IE 7] Is IE7 [if! IE] determines if it is not IE [if lt IE 5.5] and whether it is IE5.5 or earlier. (<) [If lte IE 6] determine whether it is equal to IE6 or earlier (<=) [if gt IE 5] determine whether it is IE5 or later (>) [if gte IE 7] determine whether IE7 or later [if! (IE 7)] Judging whether it is IE7 [if (gt IE 5) & (lt IE 7)] Judging whether it is greater than IE5, less than IE7 [if (IE 6) | (IE 7)] Judging whether IE6 or IE7 is a comprehensive example code for judging the IE version: <! -- [If IE]> You are using Internet Explorer. <!
