CSS Hack collection summary

Block IE browser (that is, not displayed under IE)
*:lang(zh) select {font:12px !important;} /*Special for FF*/
select:empty {font:12px !important;} /* Visible in safari*/
Here select is the selector, change it according to the situation. The second sentence is unique to the Safari browser on MAC.
Only IE7 recognition

*+html {…}
You can use this HACK when you need to make styles only for IE7.
IE6 and below identification

* html {…}
Pay special attention to this place. Many landlords have written HACK for IE6. In fact, IE5.x can also recognize this HACK. Other browsers do not recognize it.
html/**/ >body select {……}
This sentence has the same effect as the previous sentence.
Only IE6 does not recognize it

select { display /*IE6 does not recognize it*/:none;}
The main purpose here is to separate an attribute and value through CSS comments, which are released before the colon.
Only IE6 and IE5 do not recognize it

select/**/ { display /*IE6, IE5 does not recognize*/:none;}
The difference here from the above sentence is that there is an additional CSS comment between the selector and the curly braces.
Only IE5 does not recognize it

select/*IE5 does not recognize it*/ { display:none;}
This sentence is the comment in the attribute area removed from the previous sentence. Only IE5 does not recognize
Box model solution

selct {width:IE5.x width; voice-family:””}””; voice-family:inherit; width:correct width;}
The box model clearing method is not through !important to handle. This needs to be clear.
Clear floats

select:after {content:”.”; display:block; height:0; clear:both; visibility:hidden;}
In Firefox, when the children are all floating, then the height of the parent It is impossible to completely wrap the entire child, then use this floating HACK to define the parent once, then this problem can be solved.
Truncating ellipsis

select { -o-text-overflow:ellipsis; text-overflow:ellipsis; white-space:nowrap; overflow:hidden; }
This is to automatically cut off the excess part after exceeding the length The text ends with an ellipsis, which is a good technique. It's just that Firefox doesn't support it currently.
Only Opera recognition

@media all and (min-width: 0px){ select {……} }
Make separate settings for the Opera browser.
The above are some HACKs in writing CSS. These are used to solve local compatibility issues. If you want to separate the compatibility content, you might as well try the following filters. Some of these filters are written in CSS to import special styles through filters, and some are written in HTML to link or import required patch styles through conditions.

Filter for IE5.x, only IE5.x is visible

@media tty {
i{content:””;/*” “*/}} @import 'ie5win.css’; /*”;}
}/* */
IE5/MAC filters are generally not needed
