Theaming grid's checkbox with id="selectAllCheckbox"

Flow
1

Hi there.
Could you please advise how to style grid’s checkbox with id=“selectAllCheckbox”, i.e. the first checkbox in grid’s part=“cell header-cell” (1). All others (2) should stay by default or have another style, not the same as (1). Also how to remove ‘hover’ effect from first checkbox?

I tried with

:host [part="checkbox"]
 {
    background: white;
}

[part="checkbox"]
 {
    background: white;
}

but that changes all checkboxes, not just the first one in the header.

Cheers, Simon

I fixed it with ID selector.

#selectAllCheckbox {
    background: white;
}

Does the trick.
