The Horizontal Rule tag, <hr>, is a line that runs horizontally
across your page. You can just add a plain <hr>, or define it more using
CSS.
<hr style="width: 70%">
I recommend using percent to define the width or the rule since your rule will not be too wide on lower resolutions, but you can use pixels.
<hr style="width: 200px">
Along with defining the width you can define the height using the
size="" attribute set with pixels.
<hr style="height: 5px">
All of these properties can be used together like this:
<hr style="width: 50%; height: 10px">
