Day 11

 dt> Definition of a term in a description list. This element must be a child of the element <dl>, and is usually followed by an element <dd>; however, if there are <dt>multiple elements in a row, multiple terms will be defined, which will be explained by the <dd>next element.

<figcaption> A representation of a sign or explanation associated with a picture, drawing, or other thing that can be described through the element <figure>that must be the direct parent of this element.

<figure> A representation of content in its own right, usually used in conjunction with a banner (via element <figcaption>), and usually indicating an integral unit of information.

<hr> Representing a thematic break between paragraphs (e.g., a change of scene in a story, or a change of subject by creating a new section).

In previous versions of HTML, this element was displayed as a horizontal line, and it is still displayed that way in browsers, but it now has a structural meaning, rather than just being a formal element
