What are semantic html elements?

Question

Could somebody please explain? :(

Answer 1

Bitdegree.org writes “
A semantic element clearly defines its meaning both to the developer and the browser. For example, the <dd> tag does not tell much about its content. ... They are the HTML5 semantic tags.”
If you had never used html before you wouldnt know what <ul> did. That is a semantic tag. A non-semantic tag would be something like <title>

A good 5 min read with a list of semantic HTML elements.
