Placeholder
Use loading placeholders for your components or pages to indicate something may still be loading
Placeholders on BootstrapExamples
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.

Card title
Some quick example text to build on the card title and make up the bulk of the card's content.
Go somewhere<div class="d-flex justify-content-center">
<div class="card overflow-hidden" style="width: 20rem;">
<div class="card-img-top"><img class="img-fluid" src="../../assets/img/generic/1.jpg" alt="Card image cap" /></div>
<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>
</div>
<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></p><a class="btn btn-primary disabled placeholder col-6" href="#" tabindex="-1"></a>
</div>
</div>
</div>
Width
You can change the width
through grid column classes, width utilities, or inline styles.
<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 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>
Sizing
The size of .placeholder
s 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 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 placehodlers 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>
