So, the figure element specifies self-contained content, such as illustrations & photos. This means that you"ll always be using the figure tag lớn house something else.

One common misconception is that figure can only be used for images. In fact, it can be used lớn group any number of different things together, including, but not limited to, images, video, audio, và code blocks.

Defining Page Structure

The figure is a sectioning root, which means that it effectively isolates its content from its ancestor"s structure. Whatever"s inside the figure doesn"t contribute khổng lồ the document outline outside it. It behaves as a structural element of the page and can therefore contain its own headings, beginning with an  and working down the hierarchy through

Multiple Images

Using just a series of img elements lớn display images together works fine, though each individual image would standalone as its own block of code, completely unrelated to any others.

Perhaps you want to group some inline code, along with a caption, in a tutorial for example, then you could use figure and figcaption in the following way:
