Lightbox
Bootstrap 5 Lightbox component

MDB lightbox is a group of images combined in one responsive gallery. Elements are grouped in a thumbnail grid, which can be displayed as a slideshow.

Image optimization
To ensure the proper performance of the page, it is recommended to include thumbnails of
images in the src attribute. Then in the
data-mdb-img attribute add the path to the image with higher resolution. If the
data-mdb-img attribute is omitted, the lightbox will display the same image as in
the reduced size.
<img
src="https://mdbcdn.b-cdn.net/img/Photos/Thumbnails/Slides/1.webp"
data-mdb-img="https://mdbcdn.b-cdn.net/img/Photos/Slides/1.webp"
alt="Table Full of Spices"
class="w-100"
/>
Shadows and rounded corners
You can improve the look of the images by adding shadows and rounded corners.
