+##### Warning
+
+The `text-hide()` class and mixin has been deprecated as of v4.1. It will be removed entirely in v5.
+{{< /callout >}}
+
+Utilize the `.text-hide` class or mixin to help replace an element's text content with a background image.
+
+```html
+<h1 class="text-hide">Custom heading</h1>
+```
+
+```scss
+// 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.
+
+<div class="bd-example">
+  <h1 class="text-hide" style="background-image: url('/docs/{{< param docs_version >}}/assets/brand/bootstrap-solid.svg'); width: 50px; height: 50px;">Bootstrap</h1>
+</div>
+
+```html
+<h1 class="text-hide" style="background-image: url('...');">Bootstrap</h1>
+```
