HTML5MO is a collection of free, Creative Commons-licensed, CSS3, HTML5, and responsive website templates, designed and built by Doni.
Besides giving us visible credit somewhere on the site, not really.
Our responsive stuff relies mostly on vanilla CSS, but we do use some features of Skel for convenience (eg. resets and breakpoint management). If you've never used it before, be sure to check out its documentation.
Because I'm a generous guy! But seriously, most of these are the results of me trying to keep my skills sharp. It's a win win, you get free stuff and I get practice.
Sure, just contact me and we'll work something out.
