The reason being that the first one is optional and might contain more detailed text compared to the second one that is always good to exist for accessibility reasons. Note that we use a custom attribute instead of the default alt one for the image caption. If an image doesn’t need a caption on the lightbox, just don’t place such an attribute. Each slide will have an optional caption that will be determined by the data-caption attribute of the associated image.Set the width and height to 100 and absolutely position it to the top left.

Finally, width and height are set to 100% so the iframe takes up 100% of the containers’ space.Like with most absolute positioned elements, we need to set the top and left properties so the iframe get’s put in the right place.You can’t have more than 12 columns overall, but you can certainly. Using overflow: hidden is important because it ensures if any content does protrude outside of the container, it will be hidden and avoid screwing up the site’s layout.
