Verticle Rules

As there is no dedicated verticle rule tag here are a few ways to create one using a Div.

Using only one of the verticle borders.
<div style="height:100px;border-right:6px inset blue"></div>

Using a thin verticle layer with background colour
<div style="width:6px;height:100px;border:2px solid blue;background-color:#ff0000"></div>

Using a thin verticle layer with a background image
<div style="width:6px;height:100px;border:0px solid blue;background-image:url(pic.jpg)"></div>
