How to Add Bootstrap Image Captions in HTML

Want the caption on your page, not just on Instagram? Bootstrap’s figure component does it in three lines.

How to caption images in HTML? Wrap the image in a <figure> tag. Then add a <figcaption> right after it. Bootstrap adds the .figure, .figure-img and .figure-caption classes for clean, ready-made styles, as the official figure docs explain.

<figure class="figure">
  <img src="launch-day.jpg" class="figure-img img-fluid rounded" alt="Laptop showing a new website layout">
  <figcaption class="figure-caption text-end">Launch day. Fresh grid, clean look.</figcaption>
</figure>

Here is what each part does:

• img-fluid makes the image responsive. Per the docs, images in figures have no set size, so this class matters.
• rounded softens the corners.
• text-end moves the caption to the right in Bootstrap 5. In Bootstrap 4, use text-right.
• alt describes the image for screen readers. A caption is for everyone. Alt text is for people who can’t see the image.

What is a Bootstrap image? A Bootstrap image is a normal <img> tag with Bootstrap classes. W3Schools lists the classic ones for Bootstrap 3: img-rounded, img-circle, img-thumbnail and img-responsive. Bootstrap 4 and 5 use img-fluid for responsive images. Need a quick copy-paste? Bootstrap Shuffle and GeeksforGeeks both show working figure examples.

You can also tune the caption with Sass variables. Bootstrap 5 ships with $figure-caption-font-size and $figure-caption-color. Some themes add their own touches. Arizona Bootstrap, for example, adds a bottom border and extra padding to the caption.

For a photo gallery, place each figure inside a col-md-4 column. Add a modal if you want a bigger view on click. Keep each caption short so the grid stays tidy.
