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

Placeholders on Bootstrap


In the example below, we take a typical card component and recreate it with placeholders applied to create a “loading card”. Size and proportions are the same between the two.

<div class="d-flex justify-content-center">
  <div class="card overflow-hidden" style="max-width: 20rem;">
    <div class="card-img-top jhj">
      <img class="img-fluid" src="../../assets/img/generic/1.jpg" alt="Card image cap" />
    <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>
      <a class="btn btn-primary btn-sm" href="#!">Go somewhere</a>
  <div class="card overflow-hidden ms-3" style="width: 20rem;" aria-hidden="true">
    <div class="card-img-top" style="width: 320px;height: 180px"><span class="placeholder w-100 h-100"></span></div>
    <div class="card-body">
      <h5 class="card-title placeholder-glow"><span class="placeholder col-6"></span></h5>
      <p class="card-text placeholder-glow">
        <span class="placeholder col-7"></span>
        <span class="placeholder col-4"></span>
        <span class="placeholder col-4"></span>
        <span class="placeholder col-6"></span>
        <span class="placeholder col-8"></span>
      <a class="btn btn-primary disabled placeholder col-6" href="#" tabindex="-1"></a>
Card image cap
Card title

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

Go somewhere


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

<span class="placeholder bg-500 col-6"></span>
<span class="placeholder bg-500 w-75"></span>
<span class="placeholder bg-500" style="width: 25%;"></span>


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

<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>


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.

<span class="placeholder bg-500 col-12 placeholder-lg"></span>
<span class="placeholder bg-500 col-12"></span>
<span class="placeholder bg-500 col-12 placeholder-sm"></span>
<span class="placeholder bg-500 col-12 placeholder-xs"></span>


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

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