Target <h3> text by internal sibling <a> tag id

So I am using a rust markdown parser and it renders header_ids by placing an <a> tag with an id inside the <h> tags.

So I am getting something like:

<h3>
  <a href="/" id="SOMEID"></a>
  "TEXT"
</h3>

So I want to color the text thats in the <h3> tag by target it by the id thats on the <a> tag. So not target the directly because then I would color all the <h3> tags.

I tried some different css selectors and what not to target it, but nothing worked. Not even sure if thats possible.

>Solution :

you can try something like that:

h3:has(> #test) {
color: red;
}

<h3>text</h3>
<h3>text <a id="test" href="#">text</a> text</h3>
