I've 'volunteered' to help out with a local charity website. I've used Paul's 3 col and 2 col examples from the sticky here(for which many thanks) and adapted them to suit my needs, but I have a couple of queries.
Firstly the lines:
@media all and (min-width: 0px){
#left a:hover span {

(lines 138 - 142 in the 3col.css file attached to the site link below)

I'm not sure what these do and whether I need them for my site. I'm especially confused by the extra }. Of course it's possibly a hangover from where I've deleted styles not needed.

And secondly in the linked page '2007 Programme' (the only link yet set up apart from 'home' on that page) the borders to the outer style don't reach to the bottom of the page in FireFox. I've tried wading through the above mentioned sticky (but there's an awful lot of it and if it's there I must be 'searching' for the wrong terminology, and I've sat and looked at the code, but I can't for the life of me see where the error is.

I would be grateful if anyone can help.
