css - Why does .b:not(#a>.b) not work? -

-

i'm working css , wondering why following piece doesn't work:

.container:not(#topic-title>.container)

is there anyway else can achieve same thing? i'm open javascript solutions.

you use selector :

:not(#topic-title) > .container 

.container {      height:20px;  }  :not(#topic-title) > .container {      background:green;  }
<div id="topic-title">      <div class="container">parent #topic-title</div>  </div>  <div>      <div class="container"> parent not #topic-title</div>  </div>
