Semantic UI is almost an alternative to Bootstrap

Stumbled today on one interesting thing.
Semantic UI is a framework for creating portable interfaces that will help reuse UI elements in their projects. Such an alternative to Bootstrap.
A small example is if you want to add something like a button to your project.

just use the following elements:

semantic add button semantic add icon 

then add to html:

 <div class="red ui icon buttons"> <div class="ui button"> <i class="grid layout icon"></i> </div> <div class="ui button"> <i class="block layout icon"></i> </div> <div class="ui button"> <i class="list layout icon"></i> </div> </div> 

It turns out pretty nice. On the official website, everything is organized well, there are brief guides. One problem is the pre-release. Therefore, you can not download anything from offsite. To do this, go to GitHub . Already possible.
But right on the site there is a collection of basic interface elements - from buttons to simple registration forms.
The Semantic UI is just beginning to evolve, the author on the githabe even invites everyone to participate in the work on the Semantic. Contact e-mail jack@semantic-ui.com
