问题 This is in reference to a nav menu on a site I am working on: I have applied a hover style to these particular anchors (subnav buttons): ul#css3menu ul li:hover>a { Now I want to further style any of these anchors that have a child span element.

I want to match Url and regular expression and put the code under $cond. A sample data looks as {"BrandId":"a","SessionId":"a1","Method":"POST","Url":"/sample/widgets"} {

问题 This is now solved. I simplified the code. My problem now is that whenever I hover over all list items (shown below ul.menu) then hover over again, upon inspection style="display:none;" is not being removed after I come back to mouseover again.
