How to target a class in shadow root without JS?

Question

Suppose I have a html element with a shadow root.

<my-element>
#shadow-root
<div class='need-target-this' />
</my-element>

How to position the div inside the Shadow root?

I tried using

:host(my-element.need-target-this)

But that doesn't help. What am I missing here?

Answer 1

• Use the `; } connectedCallback(){ this.shadowRoot.querySelector("span").innerHTML = `Web Component!`; } });

Answer 2

In case it helps someone: I wrapped my element with div, added ref and went to

const Shadow = ref.current.querySelector('my-element').shadowRoot

const target = Shadow?.querySelector('.need-target-this')

target.style.whatever = 'value';
