How to change bootstrap 4 drop-down colors?

I know this is already answered, but since I'm bookmarking it, I want to give the solution that worked for me when theming Bootsrap using Sass and NPM.

Note that I include functions and variables above my custom ones because I need to access them otherwise the compilation will fail. Read more about it on this issue.

Suppose you have your _custom.scss like this:

@import "~bootstrap/scss/functions";
@import "~bootstrap/scss/variables";

// Add your custom variables here

@import "~bootstrap/scss/bootstrap";

Then you can go to Bootstrap's main variables file and copy over the ones you want to overwrite.

For example, if I want my dropdown background to be dark with white links I'd do it like:

$dropdown-bg:                       $dark;
$dropdown-link-color:               $light;

And my _custom.scss file after the changes would like like this:

@import "~bootstrap/scss/functions";
@import "~bootstrap/scss/variables";

// Add your custom variables here
$dropdown-bg:                       $dark;
$dropdown-link-color:               $light;

@import "~bootstrap/scss/bootstrap";

And this is an image of what it looks like after compiling Sass:

This way I don't overwrite CSS rules avoiding unnecessary clutter.


.dropdown {list-style: none; background: green; padding: 10px; display: inline-block;}
.dropdown .nav-link {color:#fff; text-decoration: none;}
.dropdown .dropdown-menu a{color: #000; text-decoration: none;}
.dropdown .btn {background: green; color:#fff;}
.dropdown .btn:hover {background: cyan; color:#000;}
.dropdown .btn:active {background: cyan; color:#000;}
.dropdown .btn:focus {background: cyan; color:#000;}
.dropdown-menu .dropdown-item {display: inline-block; width: 100%; padding: 10px 5px;}
.container .dropdown .dropdown-menu a:hover
{
  color: #fff;
  background-color: #b91773;
  border-color: #fff;
}

          aria-expanded="false">
  Dropdown link
</a>
        <div class="dropdown-menu" aria-labelledby="navbarDropdownMenuLink">
          <a class="dropdown-item" href="#">Action</a>
          <a class="dropdown-item" href="#">Another action</a>
          <a class="dropdown-item" href="#">Something else here</a>
        </div>
      </li>
</div>

</body>
</html>

Here is a some code, hope it will helps you.
