Thanks for replying, I have found the solution in the form of a Joomla extension plugin which compiles my template.less file into a template.css file when the index.php page is loaded. So that is working great, but leads me on to another question which you may be able to answer if you are already using Less....
If I import specific LESS files (eg nav.less and footer.less - made up names here) by using the '@import' function in my template.less file, is the code from those files actually being added into my template.css file as it is compiled, or are these files merely being linked to my css file? Does that question make sense?
Im asking because I havent actually tried it yet.
