Image replacement

Swap text for background images with the image replacement class.

Utilize the .text-hide class or mixin to help replace an element’s text content with a background image.

<h1 class="text-hide">Custom heading</h1>

// Usage as a mixin
.heading {
  @include text-hide;
}

Use the .text-hide class to maintain the accessibility and SEO benefits of heading tags, but want to utilize a background-image instead of text.

<h1 class="text-hide" style="background-image: url('/docs/4.0/assets/brand/bootstrap-solid.svg'); width: 50px; height: 50px;">Bootstrap</h1>
