Features of Bootstrap3. What is responsive design?
This framework was created by designer and engineer of Twitter company, so it is often used name «Twitter Bootstrap». Today Bootstrap third version has the following characteristics:
- It was originally designed for mobile devices, which usage becomes more frequent. Layout of new framework is designed suchwise, that you firstly customize design for small screens and then scale it by a widescreen device.
In Bootstrap 3 there is only one grid system – responsive (there were two before: responsive and adaptive). But its functionality has been significantly expanded to a larger number of grids of different sizes.
- Today, included fonts can be used as icons. Earlier kit included Bootstrap sprites in the format PNG. The problem was that the PNG is a bitmap, and therefore it was impossible to change the size without distortion or color. Well, in Bootstrap 3, we will have to deal with vector images (fonts) and change colors or sizes.
What is responsive design? Situation when the user visits the site only via desktop and laptop computers, have sunk into oblivion. Now, depending on the subject, traffic from mobile devices can vary from a few to tens percent from the total. Ignoring the visitors’ convenience is no longer possible.
It is not enough to simply have a website looking great and functioning only on large screens. It is necessary that it doesn’t lose its properties on the screens of various tablets and smartphones. Creating a separate site for mobile displays not the best idea (difficulty synchronizing information, the complexity of recognition, etc.).
Step in the right direction was the concept of “psd bootstrap” – where the site is able to properly adjust (respond) to the size of the user’s screen. This is done by uploading different CSS styles when viewing site on the screens of various devices. For example, on the monitor site will be displayed in three columns, in the case of the tablet – in two columns, and when from the smartphone – single column layout.
The actual content and the color scheme of the site does not change, and the only change is a way to group information units (whether on the left of the main content or, say, from the bottom). Responsive design requires more efforts from the developer, but thanks to the framework’s Bootstrap, psd-bootsrap problem will be solved.
