Solid button color style for use with the .btn base style.

<div class="mb1">
  <button class="btn btn-primary">Button</button>
  <a href="#!" class="btn btn-primary">Link Button</a>
  <input type="button" class="btn btn-primary" value="Input Button">
</div>

By default, .btn-primary has white text on a blue background.

Adjust the default colors using the --button-color and --button-background-color custom properties.

:root {
  --button-color: black;
  --button-background-color: silver;
}

Use other color utilities to handle one-off exceptions.
