Breadcrumbs CSS

I would like to change the breadcrumbs style.
I know where to change it normally in the default.css without TC CK
But of course it gets overwritten by template creator when copying the template

I cannot get it to change normally (Parameters, Block, Module in TC), so where do I put it?
In the custom css? I tried the above places, but no changes.

.breadcrumb {
margin-left: 0px;
margin-bottom: 10px;
}

Hi
you can use the custom.css file like shown in the video in the help tab of the component
