I have discovered the good use of stylesheet_link_tag and
have to use the relative_url_root way.
Now I wonder how I can use that for other URLs. I want a background image
for a table cell so I have to write something like:
<td align='right' valign='bottom' style='width: 810px; height: 113px;
background: url(<% url_for('images/header.png')%>) no-repeat center center'
(Of course the css is going to a separate file but the problem stays the
same.) What method should I use instead of url_for to do the correct url
mapping? link_to does not seem appropriate either.
Sorry for all the beginner questions!
