Starkers 320 is a mix of WordPress Starkers theme and 320 and Up mobile-first boilerplate. Quoting the original Starkers authors:

Starkers is a bare-bones WordPress theme created to act as a starting point for the theme designer. Free of all style, presentational elements, and non-semantic markup, Starkers is the perfect ‘blank slate’ for all your WordPress projects. Best of all: it’s free and fully GPL-licensed, so you can use it for whatever you like — even commercial work.

Download SASS utilities at sass-lang.com/download.html.

Update WordPress style.css with your latest changes:

make update

Tell SASS processor to rebuild style.css automagically when a SCSS file changes:

make watch

Remove the .sass-cache directory:

make clean

"Upstarts" are responsive design patterns for the things we build every day. They are included in Starkers 320 but turned off by default to save a few bytes.

To activate Upstarts uncomment these @import lines at the bottom of ./scss/style.scss:

//  11. UPSTARTS 			==============================

// Modules and panels
@import "upstarts/320andup-modules/upstart";
@import "upstarts/320andup-panels/upstart";

// Layout option using display:table for navigation positioning
@import "upstarts/320andup-display-table/upstart";

Then rebuild style.css with:

make update

There are some "Upstarts" demo files under ./scss/upstarts folder.

To activate Javascript files uncomment these lines in the "starkers_script_enqueuer" function found in functions.php file:

// Include site scripts
wp_register_script( 'site', get_template_directory_uri().'/javascripts/site.js', array( 'jquery' ) );
wp_enqueue_script( 'site' );

// Activate Modernizr, see: http://modernizr.com/
wp_register_script( 'modernizr', get_template_directory_uri().'/javascripts/modernizr-min.js' );
wp_enqueue_script( 'modernizr' );

// Include misc. helper scripts
wp_register_script( 'helper', get_template_directory_uri().'/javascripts/helper.js' );
wp_enqueue_script( 'helper' );

By enabling site.js the WordPress JQuery version is automatically included too.
