CSS problem - an element only works if its has no parent (using jquery) -


i have code:

css:

.taglist  {     float:left;     margin-left:30px; } .taglist ul  {     overflow:auto;     list-style-type:none;     border:1px solid #999;     background:#ccc;     padding:20px;     min-height:150px;     max-height:150px;     width:100px; }  .taglist li {     display:block;     border:1px solid #999;     background:#fff;     width:80px;     padding:5px 10px;     margin-bottom:5px; } .tag_selected {     background:#ffc; }

html:

<div class="taglist">     <ul id="list1">         <li id="1">1</li>     </ul> </div>

now i'm using jquery one.. when item on list selected, should change class tag_selected.

problem is, works if remove ".taglist " before ul , li css, , don't want because want style on "taglist" div..

i'v tried every combination ".taglist tag_selected", ".taglist ul li tg_selected", etc. nothing works !!

what can do?

btw, trying line:

<li class="tag_selected" id="1">1</li>

gave same result, no change ever..

thanks in advance!

your problem seems css selector specificity.

the rules .taglist ul , .taglist li more specific .tag_selected , therefore class assigned background overridden .taglist li.

this should work

.taglist li.tag_selected {     background:#ffc; }

the specificity order (weakest strongest) tag, class, id. easiest way remember calculated treat sum of each digit, tag 1s, class 10s, , id 100s.

  • li - 1
  • .taglist - 10
  • .taglist li - 11
  • li#myid - 101
  • div.taglist li.tag_selected - 22

see http://htmldog.com/guides/cssadvanced/specificity/ or google "css specificity".
