How to make a vertical line in HTML

How do you make a vertical line using HTML?

Solution 1:

Put a <div> around the markup where you want the line to appear to next, and use CSS to style it:

.verticalLine {
  border-left: thick solid #ff0000;
}

<div class="verticalLine">
  some other content
</div>

You can use the horizontal rule tag to create vertical lines.

<hr width="1" size="500">

By using minimal width and large size, horizontal rule becomes a vertical one.
