I am aware of CSS and HTML5 and a little bit of jQuery.
I am testing around with SASS and Compass. Alongside tools such as Sublime Text 2 and Codekit.
However my CSS files (minified) are totaling 106KB. I have included the Foundation 3 framework, and my own Typekit fonts. The pre-compiled size is around 35kb..
Any ideas?
Your CSS depends on your site requirements. As long as it is lean and efficient in what it does you are doing it correctly, there can not possibly be a set size for CSS/HTML or JS files!
There is this good site speed tool by Google which will help you improve speed as I am guessing that is the aim?
