Is it simple to customize the color of the close button in Bootstrap 5?

Bootstrap's v5 release brings updated styling to various components, including the close button. In previous versions, the close button had an "x" that could be easily styled with text properties, like inheriting color from its parent. However, in v5, the button is now styled using a background SVG image:

.btn-close {
  box-sizing: content-box;
  width: 1em;
  height: 1em;
  padding: .25em .25em;
  color: #000;
  background: transparent url(data:image/svg+xml,%3csvg xmlns='http://www.w3.org/2000/svg' viewBox='0 0 16 16' fill='%23000'%3e%3cpath d='M.293.293a1 1 0 011.414 0L8 6.586 14.293.293a1 1 0 111.414 1.414L9.414 8l6.293 6.293a1 1 0 01-1.414 1.414L8 9.414l-6.293 6.293a1 1 0 01-1.414-1.414L6.586 8 .293 1.707a1 1 0 010-1.414z'/%3e%3c/svg%3e) center/1em auto no-repeat;
  border: 0;
  border-radius: .25rem;
  opacity: .5;
}

To adjust the color, you can use the .btn-close-white variant which applies a CSS filter to invert the color. If you prefer a specific color and are unable to modify SCSS variables directly, there might be other methods available. Some suggestions include styling the background image with CSS filters or exploring alternative approaches to achieve your desired color customization. Feel free to explore different options and see what works best for your setup. Thank you!

Answer №1

If you're unsure if this has been addressed, consider implementing the following code snippet in accordance with Bootstrap guidelines:

<button type="button" class="btn-close btn-close-white" aria-label="Close"></button>

Answer №2

To customize the color filter, you have the option of utilizing a specialized tool like this one, or simply adjust the fill color directly within the SVG code...


.btn-close-yellow {
  background: transparent url("data:image/svg+xml,%3csvg xmlns='http://www.w3.org/2000/svg' viewBox='0 0 16 16' fill='%23fc0'%3e%3cpath d='M.293.293a1 1 0 011.414 0L8 6.586 14.293.293a1 1 0 111.414 1.414L9.414 8l6.293 6.293a1 1 0 01-1.414 1.414L8 9.414l-6.293 6.293a1 1 0 01-1.414-1.414L6.586 8 .293 1.707a1 1 0 010-1.414z'/%3e%3c/svg%3e") center/1em auto no-repeat;
}

If you're utilizing Bootstrap in a certain way, you have the option to directly adjust the variable, $btn-close-color: $primary (for instance)

Alternatively, if you prefer to use something like btn-close-primary in your HTML code, you can create a mixin.

@mixin button-close-color($color) {
     $btn-close-bg:  url("data:image/svg+xml,<svg xmlns='http://www.w3.org/2000/svg' viewBox='0 0 16 16' fill='#{$color}'><path d='M.293.293a1 1 0 011.414 0L8 6.586 14.293.293a1 1 0 111.414 1.414L9.414 8l6.293 6.293a1 1 0 01-1.414 1.414L8 9.414l-6.293 6.293a1 1 0 01-1.414-1.414L6.586 8 .293 1.707a1 1 0 010-1.414z'/></svg>");
     background: transparent escape-svg($btn-close-bg) center / $btn-close-width auto no-repeat;
    }

After that, iterate through the theme

@each $color, $value in $theme-colors {
  .btn-close-#{$color} {
    @include button-close-color($value);
  }
}
