CSS hack summary quick query manual browser compatibility required

Shield ie browsers (that is, they are not displayed under IE) CopyCode The Code is as follows: *: Lang (zh) Select {Font: 12px! Important;}/* FF visible. Note: Due to the latest update of opera, this sentence has now become a dedicated hack for FF */
Select: Empty {Font: 12px! Important;}/* safari visible */
Here, select is the selector, which can be changed as needed. The second sentence is unique to the Safari browser on Mac.

Only IE7 RecognitionCopy codeThe Code is as follows: * + HTML {...}
This hack can be used only for IE7.

Identification of IE6 and IE6 or lowerCopy codeThe Code is as follows: * HTML {...}
Note that many landlords have written the hack of IE6. In fact, ie5.x can also identify this hack. Not recognized by other browsers.
Html/**/> body select {......}
This sentence serves the same purpose as the previous one.

Only IE6 is not recognizedCopy codeThe Code is as follows: Select {display/* IE6 does not recognize */: none ;}
Here we mainly use CSS annotations to separate an attribute and a value, and the stream is prior to the colon.

Only IE6 and ie5 are not recognizedCopy codeThe Code is as follows: Select/**/{display/* IE6, ie5 does not recognize */: none ;}
The difference here is that a CSS comment is added between the separator and curly braces.

Only ie5 is not recognizedCopy codeThe Code is as follows: Select/* ie5 does not recognize */{display: none ;}
This sentence removes the comment of the attribute area from the previous sentence. Only ie5 is not recognized

Box Model SolutionCopy codeThe Code is as follows: selct {width: ie5.x width; voice-family: "\" }\ ""; voice-family: Inherit; width: correct width ;}
The box model clearing method is not passed! Important. This should be clear.

Clear floatingCopy codeThe Code is as follows: select: After {content: "."; display: block; Height: 0; clear: Both; visibility: hidden ;}
In Firefox, when the child level is floating, the height of the parent level cannot fully cover the entire child level, in this case, the floating hack can be used to define the parent level.

Ellipsis (...)Copy codeThe Code is as follows: Select {-o-text-overflow: ellipsis; white-space: nowrap; overflow: hidden ;}
This is a good technique to cut out more text and end it with a ellipsis. But Firefox does not currently support it.

Only opera RecognitionCopy codeThe Code is as follows: @ media all and (min-width: 0px) {select {......} }
Set the Opera Browser separately. The above are some hack in CSS, which are used to solve the local compatibility problem. If you want to separate the compatibility content, try several filters below. Some of these filters are written in CSS to import special styles through filters, and some are written in HTML to link or import the required patch styles through conditions.

Ie5.x filter, only visible to ie5.xCopy codeThe Code is as follows: @ media tty {
I {content: "\";/* "*/} @ import 'ie5win.css ';/*";}
}/**/

Ie5/MAC filters are generally not requiredCopy codeThe Code is as follows :/*\*//*/
@ Import "ie5mac.css ";
/**/

If condition hack of IECopy codeThe Code is as follows: <! -- [If IE]> only ie <! [Endif] -->
All ie identifiable
<! -- [If IE 5.0]> only IE 5.0 <! [Endif] -->
Only ie5.0 can recognize
<! -- [If gt ie 5.0]> only IE 5.0 + <! [Endif] -->
Both ie5.0 and ie5.5 can be identified.
<! -- [If lt IE 6]> only IE 6-<! [Endif] -->
Only IE6 can recognize
<! -- [If gte ie 6]> only IE 6/+ <! [Endif] -->
Ie5.x under IE6 and IE6 can be recognized
<! -- [If lte ie 7]> only IE 7/-<! [Endif] -->

only IE7 can identify the above content, which may not be comprehensive. You are welcome to join me in summarizing these skills to facilitate future work queries, at the same time, I would like to thank those authors who have studied these hack.
