Conditional Comments HTML - Internet Explorer Issues In Web Design

Conditional comments work in Internet Explorer and on Windows only.  For this reason, you can create special instructions to be executed by Internet Explorer only ( on Windows ). Conditional comments are for Internet Explorer 5 and higher.

The basic structure of a conditional comment is the same as an HTML comment (<!-- -->). When another browser sees such comments, they will simply ignore them.

This code snippet will target Internet Explorer 6:

<!--[if IE 6]>
Special instructions for IE 6 here
<![endif]-->

This code snippet will target Internet Explorer:

<!--[if IE 7]>
According to the conditional comment this is Internet Explorer 7<br />
<![endif]-->

This will target the browser: Internet Explorer and all versions above 5:

<!--[if IE]>
According to the conditional comment this is Internet Explorer<br />
<![endif]-->
