Am using:

!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "">
<html xmlns="">

I want to draw a line across screen to divide one section of a certain page from another [i]without[i] having to make seperate pages out of it, and haven't been able to locate any info on how to do so. Is there such a command, and if so, what is it?
