bootstrap-xxs

This project provides support for handling smaller screen sizes with Bootstrap 3 (CSS version only).
The new breakpoints are

• bootstrap-xxs.css: xxs at 480px
• bootstrap-xxs-tn.css: xxs at 480px and tn at 384px

New classes are:

• col-xxs-[1-12] with corresponding -pull-, -push- and -offset-
• hidden-xxs
• visible-xxs, visible-xxs-block, visible-xxs-inline, visible-xxs-inline-block
• Same for -tn- (only included in xxs-tn version)

Installation

1. Download the tarball or install with package managers (recommanded)

• bower install bootstrap-xxs
• or npm install bootstrap-xxs

2. Include bootstrap-xxs-tn.css or bootstrap-xxs.css in your project. This will handle all functions, but visible-xs* and hidden-xs classes.

3. For full support you need to patch your bootstrap.css with one of these methods OR use bootstrap-patched.css or bootstrap-patched.min.css

• Method 1: Use Regex to search and replace in bootstrap.css/bootstrap.min.css
  search for @media \(max-width: ?767px\)( ?\{\n? *.(visible|hidden))
  replace with @media (min-width: 480px) and (max-width: 767px)$1
  Should be 5 matches.
• Method 2: Apply bootstrap.css.patch (unminified only)

Usage

Same usage as for xs, sm, md or lg.

Testing

There is a small (and ugly) script, which shows the recognised device size, browser width and calculates the difference to the next breakpoints. It requires jQuery (tested only with v1.11.1). Include bsdebug.min.js in your project (after jQuery), reload.
Now resize your browser and watch the overlay.

Alternative: Use this bookmarklet. Create a new bookmark with target:

javascript:(function%20(){var%20n=document.createElement('script');n.setAttribute('language','JavaScript');n.setAttribute('src','http://manueltransfeld.de/js/bsdebug_bookmarklet.min.js');document.body.appendChild(n);})();
