Adblock. Add css class or remove attribute from element

Is it possible to add css rule to an element at some page by adblock? Something like this

#myElement {
    color: white !important;
}

I tried to find a script that updates style of this element on page load but it seems that it is not a best way.

Solution

It's possible to do it on uBlock Origin and AdGuard. Each has its own syntax for the styling rules, but each is now capable understanding both.

Here is an example of a CSS rule that changes Twitter background:

twitter.com#$#body.logged-in{ background-color: #8c8787 !important; }

The styling filters should be constructed like this:

<domain> + #$# + <selector> + { <style> }

Just avoid puting a space between the selector and the opening brace. Cause it can give you some trouble. Reference:
