HTML: Vertical line

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

<div class="verticalLine">

some other content

</div>
in CSS:

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

<hr width = "2" size="100" >

Simple, just place that HR, but make it very short, then very HIGH.
