html - Does the CSS direct decendant (>) not have any value in selectivity?

Given the following class declarations and code...

.foo > a { color:green; }
.bar a { color:red; }
<div class="bar">
    <div class="foo">
        <a href="#">SOME LINK</a>
    </div>
</div>

There's no value for > for css specificity.

Both case have 11 value for specificity:

.foo > a { color:green; }/*specificity value is 11*/
.bar a { color:red; }/*specificity value is 11*/

In your case you may use like this to have greater specificty:

.bar .foo > a { color:green; }/*greater specificity value is 21*/
.foo a { color:red; }/*specificity value is 11*/

Ok, I'm going add here how specificity works:

Selector                          Specificity         Specificity in large base
inline-style                      1 0 0 0             1000
id selector                       0 1 0 0              100
class,pseudo,attribute selector   0 0 1 0               10
type selector and pseudo elements 0 0 0 1                1
