What tags are used to create definitions in HTML?

To create definitions in HTML, the appropriate tags include <dl>, <dt>, and <dd>. The <dl> tag defines a description list, which is a container for your terms and their descriptions. Within this list, the <dt> tag is used to specify a term or name, while the <dd> tag provides the definition or description of that term.

This structure allows you to organize content in a clear and semantic way, which is particularly beneficial for accessibility and improving the understanding of definitions. For instance, when a screen reader encounters these tags, it can convey the relationship between terms and their definitions, enhancing the user experience for individuals with disabilities.

The other options present tags that aren't valid for creating definitions. Tags such as <def> and <li> do not serve the purpose of defining terms in HTML, leading to confusion regarding the definition list concept. Therefore, the combination of <dl>, <dt>, and <dd> is essential for effectively structuring definition lists.
