HTML dl, dt, and dd (maybe this is a tag you haven't used, but they are very useful), dtdd
I. About dl dt dd

Html <dl> <dt> <dd> is a combination of tags. When the outer layer of dt dd is used, the dl package must be used. This combination tag is also called a table tag, similar to a table combination label, we call it a dl table (Extended reading: table tr td, table tr th table layout ).

<Dl> <dt> </dt> <dd> </dl> is a common title + list tag. If no initial CSS style is set for the dl dt dd tag, the content of the default dd list will be indented. (Extended reading: ul li, ol li, and li lists)

Ii. dl dt dd list label syntax

<Dl>
<Dt> List title </dt>
<Dd> list content </dd>
<Dd> list content </dd>
...
</Dl>

Syntax explanation:
Dt and dd are placed in the dl tag, and the tag dt and dd are in the same level under the dl tag. That is, dt cannot be placed in dd, and dd cannot be placed in dt. In dl, dt and dd are at the same level. DD labels can be several. At the same time, the dt label or dd label cannot be used separately without adding dl.
