Browser conditional annotation theory, using the following example to explain the problem

X Html

The following section of code is the effect of testing conditional comment statements under Microsoft's IE browser:

<!--[If ie]>
<! [endif]-->
<!--[if IE 5]>
<! [endif]-->
<!--[if IE 5.0]>
<! [endif]-->
<!--[if IE 5.5]>
<! [endif]-->
<!--[if IE 6]>
<! [endif]-->
<!--[if IE 7]>
<! [endif]-->

The following code is a conditional comment that runs in a non-IE browser:

<!--[if! ie]><!-->
<!--<! [endif]-->
Ultimately works in non-IE and special IE browsers
(or use LTE LT or GT GTE to judge, such as:
<!--[If LTE IE 6]>
Information displayed under IE 6
<! [endif]-->
).

<!--[if IE 6]><!-->
or a non-ie browser <!--<! [endif]-->

Conditional comments are only supported by IE after Ie5.0/win, and are generally used for hack.

The following section of code is the effect of testing conditional comment statements under Microsoft's IE browser

<!--[If ie]>
Judging by the conditions, this is the Internet explorer<br/>
<! [endif]-->
<!--[if IE 5]>
According to the conditions, this is Internet Explorer 5<br/>
<! [endif]-->
<!--[if IE 5.0]>
According to the conditions, this is Internet Explorer 5.0<br/>
<! [endif]-->
<!--[if IE 5.5]>
According to the conditions, this is Internet Explorer 5.5<br/>
<! [endif]-->
<!--[if IE 6]>
According to the conditions, this is Internet Explorer 6<br/>
<! [endif]-->
<!--[if IE 7]>
According to the conditions, this is Internet Explorer 7<br/>
<! [endif]-->
<!--[if GTE IE 5]>
Depending on the condition, this is Internet Explorer 5 or higher <br/>
<! [endif]-->
<!--[If Lt IE 6]>
According to the conditions, this is the version of the Internet explorer<br less than 6/>
<! [endif]-->
<!--[If LTE IE 5.5]>
Depending on the condition, this is Internet Explorer 5.5 or lower <br/>
<! [endif]-->

The following code is a conditional comment that runs under a non-IE browser

<!--[if! ie]><!-->
You are not using the Internet explorer<br/>
<!--<! [endif]-->
<!--[if IE 6]><!-->
You are using Internet Explorer version 6<br/>
or a non-ie browser <br/>
<!--<! [endif]-->

The following is the syntax for conditional annotations:

[List]
[*]gt/greater than/greater than/<!--[if GT IE 5.5]>
[*]gte/greater than or equal to/greater than or equal to/<!--[if GTE IE 5.5]>
[*]lt/less than/less than/<!--[if Lt IE 5.5]>
[*]lte/less than or equal to/less than equals/<!--[if LTE IE 5.5]>
[*]! /note/is not equal to/<!--[if! IE 5.5]>
[/list]

IE conditional annotations of excellent browser-differentiated capabilities, allowing many designers to use hack to resolve browser differences in CSS parsing

<!--[if IE6.0]]
<style type= "Text/css" >
div#box{width:500px;margin:10px; padding:10px; border:10px;}
</style>
<! [endif]-->
<!--[if Lt IE6.0]]
<style type= "Text/css" >
div#box{width:530px;margin:10px; padding:10px; border:10px;}
</style>
