What is the html tag used to draw a vertical line?

Answer 1

You can't do that, it would just mess up the whole flow of the document. You can still imitate it with divs:

<div style = "width: 1px; height = 90%"></div> -> A vertical line with 1 px width and 90% screen height

Answer 2

Ebenye Martin you can draw vertical line with the <hr> tag
 <hr width="1" size="100">
Or you can use svg for draw vertical line

<svg id="1" width="100" height=200">
<line x1="20" y1="20" x2="20" y2="130"></line>
</svg>
