‘320 and Up’ is a lightweight, easy to use and content first responsive web design boilerplate.
This is the new ‘320 and Up’
A lot’s changed since I wrote the original ‘320 and Up’, my ‘tiny screen first’ responsive web design boilerplate. Back then we were just getting started with responsive web design and many sites, including mine, and frameworks and boilerplates like HTML5 Boilerplate, structured their CSS3 Media Queries from the desktop down, rather than for small screens up.
To put things right, I wrote ‘320 and Up’. It worked as an extension to HTML5 Boilerplate or a set of standalone files. ‘320 and Up’ has been used by designers and developers all over the web and I’ve used versions of it on every website I’ve worked on since I wrote it.
What’s in the new ‘320 and Up’?
- Five CSS3 Media Query increments: 480, 600, 768, 992 and 1382px
- Design ‘atmosphere’ (colour, texture and typography) separated from layout
- Bootstrap styles for buttons, forms and tables
- Modernizr, Selectivizr, responsive type tester and design tester
- LESS and Sass mixins and variables
- Upstarts for the things we build every day
