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.

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

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

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.

Create placeholders with the .placeholder class and a grid column class (e.g., .col-6) to set the width. They can replace the text inside an element or as be added as a modifier class to an existing component.

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