I have an effect that works fine in Firefox, but not in IE. The code is as follows:
<!DOCTYPE html><html xmlns="http://www.w3.org/1999/xhtml"><head><meta http-equiv="Content-Type" content="text/html; charset=utf-8" /><title>无标题文档</title></head><style class="csscreations">/*Now the CSS*/* {margin: 0; padding: 0;}.tree ul { padding-top: 20px; position: relative; transition: all 0.5s; -webkit-transition: all 0.5s; -moz-transition: all 0.5s;}.tree li { float: left; text-align: center; list-style-type: none; position: relative; padding: 20px 5px 0 5px; transition: all 0.5s; -webkit-transition: all 0.5s; -moz-transition: all 0.5s;}/*We will use :before and :after to draw the connectors*/.tree li:before, .tree li:after{ content: ''; position: absolute; top: 0; right: 50%; border-top: 1px solid #ccc; width: 50%; height: 20px;}.tree li:after{ right: auto; left: 50%; border-left: 1px solid #ccc;}/*We need to remove left-right connectors from elements without any siblings*/.tree li:only-child:after, .tree li:only-child:before { display: none;}/*Remove space from the top of single children*/.tree li:only-child{ padding-top: 0;}/*Remove left connector from first child and right connector from last child*/.tree li:first-child:before, .tree li:last-child:after{ border: 0 none;}/*Adding back the vertical connector to the last nodes*/.tree li:last-child:before{ border-right: 1px solid #ccc; border-radius: 0 5px 0 0; -webkit-border-radius: 0 5px 0 0; -moz-border-radius: 0 5px 0 0;}.tree li:first-child:after{ border-radius: 5px 0 0 0; -webkit-border-radius: 5px 0 0 0; -moz-border-radius: 5px 0 0 0;}/*Time to add downward connectors from parents*/.tree ul ul:before{ content: ''; position: absolute; top: 0; left: 50%; border-left: 1px solid #ccc; width: 0; height: 20px;}.tree li a{ border: 1px solid #ccc; padding: 5px 10px; text-decoration: none; color: #666; font-family: arial, verdana, tahoma; font-size: 11px; display: inline-block; border-radius: 5px; -webkit-border-radius: 5px; -moz-border-radius: 5px; transition: all 0.5s; -webkit-transition: all 0.5s; -moz-transition: all 0.5s;}/*Time for some hover effects*//*We will apply the hover effect the the lineage of the element also*/.tree li a:hover, .tree li a:hover+ul li a { background: #c8e4f8; color: #000; border: 1px solid #94a0b4;}/*Connector styles on hover*/.tree li a:hover+ul li:after, .tree li a:hover+ul li:before, .tree li a:hover+ul:before, .tree li a:hover+ul ul:before{ border-color: #94a0b4;}/*Thats all.

For example
http://api.jquery.com/after/
http://api.jquery.com/before/

IE6 7 8 does not support last-child! Solution
This style is often used together in CSS3, but
is not compatible with IE.
There is no good solution.
If you want to be compatible with IE, it is best not to use this and use another method.
