HTML Description List OR HTML Definition List Example


Do not use this element (nor <ul> elements) to merely create indentation on a page. It is a bad practice and obscures the meaning of description lists. Each screen reader announces <dl> content differently. To change the indentation of a description term, use the CSS margin property.
