Placeholders

Use loading placeholders for your components or pages to indicate something may still be loading.

Example

...

Card title

Some quick example text to build on the card title and make up the bulk of the card's content.

 <!-- example -->
  <div class="card">
    <img src="../assets/images/placeholder/4by3.jpg" class="card-img-top" alt="...">
    <div class="card-body">
       <h5 class="card-title">Card title</h5>
       <p class="card-text">Some quick example text to build on the card title and make up the bulk of the card's content.</p>

    <div class="card-body">

Width

You can change the width through grid column classes, width utilities, or inline styles.

 <!-- width -->
<span class="placeholder col-6"></span>
<span class="placeholder w-75"></span>
<span class="placeholder" style="width: 25%;"></span>

Color

By default, the placeholder uses currentColor. This can be overridden with a custom color or utility class.

<!-- color -->
 <span class="placeholder col-12"></span>
 <span class="placeholder col-12 bg-primary"></span>
 <span class="placeholder col-12 bg-secondary"></span>
 <span class="placeholder col-12 bg-success"></span>
 <span class="placeholder col-12 bg-danger"></span>
 <span class="placeholder col-12 bg-warning"></span>
 <span class="placeholder col-12 bg-info"></span>
 <span class="placeholder col-12 bg-light"></span>
 <span class="placeholder col-12 bg-dark"></span>

Sizing

The size of .placeholders are based on the typographic style of the parent element. Customize them with sizing modifiers: .placeholder-lg, .placeholder-sm, or .placeholder-xs.

 <!-- sizing -->
 <span class="placeholder col-12 placeholder-lg"></span>
 <span class="placeholder col-12"></span>
 <span class="placeholder col-12 placeholder-sm"></span>
 <span class="placeholder col-12 placeholder-xs"></span>

Animation

Animate placeholders with .placeholder-glow or .placeholder-wave to better convey the perception of something being actively loaded.

 <!-- animation -->
 <p class="placeholder-glow">
 <span class="placeholder col-12"></span>
 </p>
 <p class="placeholder-wave">
 <span class="placeholder col-12"></span>
 </p>
