What is Responsive Web Design?
Responsive Web is a web version can only run on all devices such as personal computers, smartphones or tablets. Responsive Web has the ability to automatically resize text and images for a wide variety of different screen sizes to make sure that the website is accessible and easy efficiently on any device.

Benefits of Responsive Web
- The mobile devices are used increasingly more. The use of the web on mobile devices is growing at a very fast speed, it opens up a great opportunity for you if you use it up before your competitors. If you do Responsive Web ahead of your competitors, you will have the chance of winning is very high competition.
- Save time and costs. Responsive Web can significantly reduce the time and money for the development of the website. Rather than having to spend time and money for the development of individual sites to run different devices, then Responsive Web can help you optimize the development of Web sites developed by just one single web version to run on all devices.
- Better SEO for your websites on mobile devices

Here I'd like to introduce Best Responsive CSS Framework for 2014 and 2015

1. Gumby
Gumby Framework is a choice for those who need a framework is available on the UI defaults to the construction site in a snap without having to spend time on the UI design for each CSS. Some features that I liked Gumby Framework as following:

- Full support for UI toolset necessary as buttons, navigation, forms, Icon, Javascript, jQuery UI Plugin, ... .noi be sufficient to build one site according to modern technological standards.


2. Foundation
Foundation provides all the necessary class to your style interface built from Responsive Grid System, Block Grid, Javascript libraries to enhance support for mobile devices. And some other stuff will surely make you happy.
Basically, the default Foundation is not very good. Bootstrap can say is lost in terms of style built. Foundation focuses on the basic layout building was part of beauty is sure to be under their makeup back then, which is the main purpose of the Framework. And the Foundation has done as well.


3. Skeleton
Skeleton pretty lightweight, easy to use which is good for a Framework can beat the competitions, It has the same features with others.
It only includes grid system, simple style for buttons and forms. However, you can easily develop it according your ways.


4. The Responsive Grid System
This Framework will give you a 100% grid system and responsive. Also Grid Framework System was built with the design elements such as buttons, drop down menus,...etc. You have to design. Responsive Grid System can be similar as the foundation and suits to you to start building responsive web layouts.

Base CSS Framework is super simple and it was build for all web layouts to display as well on all devices small or big in every screen sizes

This frameWork gives you more opportunities to get more orders from freelancer sites because your customers liked this framework.


What about you? which Responsive CSS Framework are you using and why?
I'd like to hear your ideas

I'm using Skeleton on one of my wordpress theme, it's easy to control and using. All elements from Skeleton can be easy for users to make a new website theme from scratch without spending more time for learning it.

In other words, I will try other Responsive CSS Framework, I think each one will have its advantages and I will find best one to select right one for me.

I will give it to Bootstrap

For some small web projects I would go with Skeleton but for large projects, maybe I will choose Bootstrap because I heard more good features from it and it is used by more big websites today.

Good information you have shared nice.
Personally i prefer bootstrap frame work to design responsive websites with HTML5 and CSS3. But there are awesome alternatives to bootstrap which can reduces our work and speed up the quality. Following are the alternatives to bootstrap frame work:
Semantic is attracted me very much with best UI and jquery features.
Zimit, InK, HTML KickStart, YUI are also becoming popular these days.
Popular restaurants search website zomato is designed and developed with YUI frame work. YUI frame work is getting great demand these days. You can learn and work on Semantic and YUI frame works to get good salaries in the present Web job market.
