Can you make vertical lines too, not just horizontal ones? And also, is there any way to adjust where on the screen your horizontal line is?

you can do all taht uisngr frames! a very thin colmun can look like a v line..

vertical lines may be simulated by using an image (easier) or a table (a bit harder). they don't really exist by themselves like the HR does.

i haven't tried it, but you can proably use css and absolute positioning to move and position an HR on your page like any other object. try asking your question about that in the css question section.

I asked about that a long time ago, and I was told you need to make an image :)

the best way is to either use tables and css or an image.

with the tables and css you'd have to make the layout using tables and css to make one side of the cell visible.
