28,558 PointsIn this specific example they would have the same effect. But in a lot of other situations they would not.
The +
selector will only target an element if it is directly next to the other element you specify so h2 + p
would select p
elements directly besides h2
elements. The ~ selector selects all sibling elements that match the selector so h2 ~ p
would select all p
elements that followed a h2
element and shared the same parent.
It is easiest to explain with a simple illustration:
<div>
<h2>Test</h2>
<p>P1</p>
<p>P2</p>
</div>
The h2 + p
selector would only select P1
since that is the only p
element directly next to a h2
element. The h2 ~ p
selector would select both P1
and P2
since they are both preceded by a h2
element that shares the same parent element.
