Partial polyfill for Regions

This polyfill makes CSS3 Regions cross-browser and cross-platform. It uses binary search to find the position of the words, which makes it run really fast.

About CSS Regions

CSS regions allow content to flow across multiple areas called regions. These regions are not necessarily contiguous in the document order.

Basic setup

var reg = new Regions(document.getElementById('article'));
reg.flowTo(document.getElementById('part_2'));
reg.flowTo(document.getElementById('part_3'));
reg.flowTo(document.getElementById('part_4'));
reg.split();

Chaining

(new Regions(document.getElementById('article'))).
  flowTo(document.getElementById('part_2')).
  split();

Events

  var reg = new Regions(document.getElementById('article'));

    reg.requestNewRegion = function() {
      var region = document.createElement('div');
      region.className = 'region';
      document.body.appendChild(region);
      this.flowTo(region);
    }

    reg.requestRemoveRegion = function(region) {
      this.removeRegion(region);
      region.parentNode.removeChild(region);
    }

    reg.split();

  }

jQuery build-in plugin

$('.article').region('flowTo', $('.article_part'));

Checking native support for CSS3 Regions
