I was using the <hr/> tag in an html page, and it was rendering fine when viewed in the browser. However, when I printed the page, nothing printed. The HR tag (the line itself) did not print. I was using CSS to style the HR tag.
It turns out the CSS syntax seems to be very picky. After playing around, I finally got this exact CSS code to work:
hr {
border-color: #000000;
border-style: solid;
border-width: 2px 0 0;
clear: both;
margin: 0 0 0px;
height: 0;
}
The line both viewed properly in the browser and it printed properly as well.
