Bootstrap Responsive Layout

In this tutorial you will learn how to create responsive websites with Bootstrap framework.

What is Responsive Web Design

Responsive web design is a process of designing and building websites to provide better accessibility and optimal viewing experience to the user by optimizing it for different devices.

With the growing trend of smart phones and tablets, it has become almost unavoidable to ignore the optimization of sites for mobile devices. Responsive web design is a preferable alternative and an efficient way to target a wide range of devices with much less efforts.

Responsive layouts automatically adjust and adapts to any device screen size, whether it is a desktop, a laptop, a tablet, or a mobile phone. See the following Illustration.

Creating Responsive Layout with Bootstrap

With the Bootstrap 4 powerful mobile first flexbox grid system creating the responsive and mobile friendly websites and applications has become much easier.

Bootstrap 4 is responsive and mobile friendly from the start. Its five tier grid classes provides better control over the layout as well as how it will be rendered on different types of devices like mobile phones, tablets, laptops and desktops, large screen devices, and so on.

The following example will create a responsive layout that is rendered as 4 column layout in extra-large devices (viewport ≥ 1200px), and 3 column layout in large devices (992px ≤ viewport < 1200px), whereas 2 column layout in medium devices (768px ≤ viewport < 992px), and 1 column layout in small and extra-small devices (viewport < 768px). Let's see how this works:
