I asked a colleague at work about the icon set that she used for a site so that I could use them on this site, she replied with ‘font awesome’ (thanks pam)
through that I found bootstrap.
what an awesome thing that is.
It contains a responsive, fluid and static grid
css for typograph, tables, forms, buttons, images, icons
css for awesome dropdown menus, navigation, breadcrumbs, buttons, alerts, modal windows, progress bars
