Hi there,
That means a is child of h3, example
This will work
h3 a {
}
in any of this code
<h3><a>Hi</a></h3>
<h3><span><a>Hi</a></span></h3>
It selects child selector regardless of hierarchical level.
While this one works too
h3 > a {
}
But for this one only, selecting the direct child.
<h3><a>Hi</a></h3>
Thanks.
