Bootstrap is a free, open-source front-end framework. It’s the most famous and powerful front-end framework for web projects today. It was born at Twitter as a responsive solution with standard elements that help developers create mobile-first, front-end interfaces quickly and intelligently.It is the most popular HTML, CSS, and JS framework for developing responsive, mobile first projects on the web.
Originally called Twitter “Blueprint,” it was in fact a library. The team at Twitter created it for internal company tasks and to standardize UI components, but after receiving positive feedback from their colleagues, Mark Otto and Jacob Thornton decided to make the project public and open-source by putting the Bootstrap code on GitHub. That was four years ago and since then, there have been over 11,777 commits to its official repository (based on its GitHub bio).
Mobile-friendly, responsive websites are no longer good-to-haves—they’re must-haves. With more people than ever before opening email, browsing the web, and shopping on their mobile devices, it’s imperative to have a mobile-first mindset. If your site isn’t responsive and optimized for mobile browsing, your bounce rates will rise and your site ranking will drop.The most popular way to build responsive sites right now is with the Bootstrap framework. It’s lightweight, fast, and easy to use.
Responsive design creates websites that automatically adjust to look good and function well on any size screen. From navigation and the way content is organized, to buttons and image scalability, responsive sites are not only designed to optimize the way people see a site, but also to prioritize what information mobile users are there to get. For example, for a large retailer, prioritizing information about finding nearby stores makes sense for mobile users vs. desktop users.
you know you need a responsive mobile site. If your site wasn’t designed to be responsive, you’ll need to redesign or retrofit it. But if you’re planning to build a responsive mobile website or application from scratch, the Bootstrap framework is an excellent choice for a few reasons.
A mobile-first, ground-up grid approach. If a site looks good on a small screen, it’s easy to scale it up from there, without things getting cluttered. A top-down approach in mobile design is counterintuitive; Bootstrap reinforces that, so sites stay clean and logical on the smallest screens. Bootstrap forces designers to build sites with small screens in mind, then go from there.
Bootstrap easily and efficiently scales your websites and applications with a single code base, from phones to tablets to desktops with CSS media queries.
create transition effects, image galleries, image carousels, alert messages, tooltips, dashboards, sticky footers, buttons, progress bars, popovers, pagination, drop-down menus, cover pages, and the ScrollSpy plug-in, which automatically updates a nav bar for the user, depending on where they are on the page.
Bootstrap design templates include features like typography, forms, buttons, tables, different navigation styles, modals, and more.
It’s compatible with Chrome, Firefox, Internet Explorer 8 and up, Safari, and Opera. Note: Bootstrap will degrade some of its features by default to work on older browsers.
