Do you want to hide it for specific categories or show it only in specific categories?
In common / CSS of a theme component:
Hide for a specific category where <category-slug-here> = the category slug:
.category-<category-slug-here> .welcome-link-banner-wrapper {
display: none;
}
Show only for a specific category:
.welcome-link-banner-wrapper {
display: none;
}
.category-<category-slug-here> .welcome-link-banner-wrapper {
display: block;
}
Hide for multiple categories:
$categories: 'general', 'site-feedback', 'staff';
@each $category in $categories {
.category-#{$category} .welcome-link-banner-wrapper {
display: none;
}
}
