Launched on August 2011 by Mark Otto and Jacob with almost 235 contributors working on its developments. Twitter Bootstrap became one of the widely used framework on the internet today. This powerful front-end framework offers a wide variety of customization to suit your unique style. Bootstrap is also well-documented; you’ll never get lose track of all the developments and latest updates. You can start creating your project by downloading their framework from here: http://getbootstrap.com/2.3.2. There’s also this thing called FBootstrapp. This toolkit is designed for Facebook iframe apps and design. But it’s free to use under Apache License v2.0.
Created by Zurb, this Framework got plenty of attention (me included) because of its highly customizable interface. You can do almost anything! Zurb provided pre-made templates for quick prototyping and styling. You can also download its source code for free. This Framework has 237 contributing developers and is one of the most used framework by web designers and web developers. Foundation Framework works well with other customization too . You can play around its CSS. Just know the basics first and you’re good to go!
The web’s most popular front-end template would be the HTML5 Boilerplate. Paul Irish, the developer of HTML5 Boilerplate created this as a development tool (or styling tool, I should say). He said it is more of a template tool rather than a framework tool.
But even though if it’s not a framework, most developers still used it as such. Built under Multiple open-source licenses in April 2010, HTML5 Boilerplate is still the top HTML5 Framework choice. With its 157 contributing developers, Boilerplate delivers well-documented updates on all released versions.
