How to change color for mat-divider?

Question

Is it possible to change mat-divider color? I tried the following, it didn't work

component.html

<mat-divider class="material-devider"></mat-divider>

component.scss

.material-devider {
    color: red
}

Answer 1

Yes, you can.

You need to overrule .mat-divider class styling in your own written CSS and change the border-top-color property.

.mat-divider {
    border-top-color: rgba(0, 0, 0, 0.12);
}

is the default styling by Angular Material.

.mat-divider {
    border-top-color: red;
}

This should be enough to change it (if your CSS gets rendered later than Material's). Otherwise adding increased specificity to your CSS class will help (f.e..mat-divider.mat-divider).

StackBlitz example for this case.
