Bar on the side of the heading - html

Question

I can't figure this one out. I have a heading (H1) and a colored bar on the right side of the heading. The bar should always cover the area between end of the heading and end of the content area. Something like that:
LOREM IPSUM ================================================
LOREM IPSUM DOLOR SIT AMET =================================
At this point, everything works fine. HTML:
<h1>LOREM IPSUM</h1><hr/>
<div class="clear"></div>
<p>Lorem ipsum dolor sit amet.</p>
and CSS:
h1 { float: left; margin: 0 10px 0 0; font-size: 18px; }
hr { display: block; border-top: 18px solid green; }
.clear { clear: both; }
See jsfiddle
Problem is that this approach doesn't work with multiline heading, it would be perfect to have something like this (so the colored bar appears on the last row):
LOREM IPSUM DOLOR SIT AMET, CONSECTETUR ADIPISCING ELIT.
PROIN SAGITTIS DICTUM RISUS A DAPIBUS ========================
Any ideas? :-)

What about this approach on jsfiddle
HTML:
<h1><span>LOREM IPSUM<br />TEST</span></h1>
<div class="clear"></div>
<p>Lorem ipsum dolor sit amet, consectetur adipiscing elit. Mauris odio magna, rhoncus sed leo et, dapibus adipiscing metus. Donec cursus dignissim ipsum sit amet suscipit.</p>
CSS:
h1 {
float: left;
margin: 0 10px 0 0;
font-size: 18px;
display:block;
background:green;
width:100%;
padding:0;
}
h1 span {
background:#FFF;
padding-right:10px;
display:inline-block;
}
.clear { clear: both; }
