Bootstrap 3: Most Popular Framework for Responsive Websites


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. Case in point: Google’s recent algorithmic shift to favor mobile-friendly sites.

The most popular way to build responsive sites right now is with the Bootstrap framework. It’s lightweight, fast, and easy to use, but beyond that what is Bootstrap, and why should you choose it as your front-end framework? In this article, we’ll look at responsive design and some of Bootstrap’s key features.

What is Responsive Design?

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.

Why Should I Choose The Bootstrap Framework For My Website?

So, 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.

Just enough customization. Not all Bootstrap sites look like Bootstrap sites meaning, how customized your site gets is up to you. On the spectrum of front-end design, with completely coded-from-scratch sites on one end and CMS-powered sites with dropped-in templates on the other end, Bootstrap falls right in the middle. It’s the best of both worlds: A lot of the work is already done in advance, with the grid system and lots of helpful components. And with JavaScript effects and customizable Bootstrap CSS, it’s as unique as you want it to be.

A mobile-first, ground-up grid approach. Bootstrap gets designers to start small. 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’s grid-based layout approach is the key: you can use up to 12 columns in a layout, combining them for wider columns, which are organized in layout classes extra small, small, medium, and large for phone, tablet, and desktop-sized screens.

It’s fast and easy to use. Bootstrap lets developers (even back-end developers) build front ends without a ton of HTML or CSS knowledge. Whether you’re applying Bootstrap to a static HTML site, a custom PHP-coded site, or a content management system (CMS), it’s flexible. Plus, it’s downloadable right from GitHub and lets developers get a lot of work done quickly.
