Bootstrap responsive

Responsive web design (RWD) is a web design technique for creating websites adaptable to the screen resolution of various devices such as desktop computers, laptops, smartphones, tablets and web TVs.

We have all navigated using mobile phones on sites that do not adopt the RWD (responsive web design) having to scroll and resize the web page to be able to view its contents, an operation that is annoying and not very usable.

Fortunately, starting in 2011 new tags were born for HTML5 and CSS3 that with the help of special JavaScript allows adaptability for every type of device resolution to access web pages.

There are various types of responsive bootstrap such as Twitter and Getbootstrap which, with the use of JavaScript, html5 and CSS3 style sheets, allow to obtain a resolution suitable for all types of devices; to test the virtual resolution of a website you can use the keyboard combination ctrl shift m for Firefox or ctrl shift i for Chrome.
