I know you ask for more beginner oriented websites but here are some that can also help, web design wise (those I use) :
- Ideas / inspiration :
http://tympanus.net/codrops/ (great site honestly, Mary Lou is just too good of a programmer)
- Ideas / inspiration :
http://www.designbombs.com/ (a good amount of sites are linked there, if you need some help design-wise)
- Basics :
http://www.w3schools.com/ (A go to site when you forget basic stuff, easy to navigate, also have a ton of tutorials)
- Color schemes :
http://colorschemedesigner.com/ (I'm more a monochromatic guy so this tool is great to me, but I also lke the analogic scheme
- Fonts :
http://www.fontsquirrel.com/ (Free fonts even for commercial use)
- Icons :
http://icomoon.io/app/#/select (Icons as fonts, great for all resolutions)
- Responsive design :
http://www.metaltoad.com/blog/simple-device-diagram-responsive-design-planning (A great piece about different resolutions and how to be efficient with media queries)
- Markup checking :
http://validator.w3.org/ (Mandatory IMO before finishing any site)
- Markup checking :
http://nibbler.silktide.com/ (It's a funny site where you can test your site, SEO wise, markup wise, social network wise and also see if you're doing everything possible to reach potential viewers
