Sometimes all you need to accent your HTML is a line across the page. To do this, you use the horizontal line tag:
<hr />.
While there are several deprecated attributes of the <hr/> tag, it is recommended that you avoid them and use CSS to style your lines. The advantage to using style sheets is that you can do so much more than just change the width or height of your lines.
<hr style="height:1.5em;width:25em;border:1px solid #000;" />
