Hi,
Just wanted to let everyone know that Silverstripe can work really well with the HTML5 Boilerplate framework: http://html5boilerplate.com/
I just used it to create this site: http://quintessentialcool.com which was recently added to the community showcase (thumb it if you like it!)
I simply started with a completely empty theme, then modelled my Page.ss on the index.html from HTML5 Boilerplate. Put the boilerplate style sheet into the theme's CSS folder, put the javascript libraries into the theme's javascript folder and built it up from there. No forms.css, typography.css or layout.css (although I could have split the HTML5 Boilerplate stylesheet into those components, for some reason I prefer keeping everything in one file as long as I'm reasonably neat).
I recommend this for anyone who really wants to feel like they're starting a Silverstripe project with a clean slate on which you can build a custom design.
Oh, I also make use of the media "screen" attribute in the link tags in the HTML head to achieve a somewhat responsive design optimised for iphone. Again I found this was also easier to do when the site started from a clean slate.
Let me know what you think.
Regards,
Adrian
