Li and UL Problems

Ul is unordered
OL is ordered
Li is their child Column
Ul ol Li is very useful.
Most of them use it now
However, those vertices and serial numbers in front of them are not so elegant.
So we need to define a CSS to remove it.
List-style-type: none; (remove the sequence number and the preceding vertex) margin: 0px; (blank page) Text-align: Left; (left-aligned text)
In this way, the point or serial number defined by Li can be removed and left aligned. Of course, you can center or right aligned.
