Solution to nth child incompatibility in low version IE

It is well known that nth child is an attribute of CSS3, which is supported in browsers that support CSS3, but not in the lower version of the wonderful IE browser. In order to make the lower version of IE also support the nth child selector of CSS3, we can use jquery See the following code:

 .list li:nth-child(4n){margin-right:0;} In this way, direct writing can only be displayed normally in browsers that support CSS3. $(document).ready(function(){ $(".list li:nth-child(4n)"). css ("margin-right","0"); }); Write in jquery, and it will be displayed well in IE browser.
