What is Responsive Web Design? Responsive web design makes your website look great on all devices no matter which device your customers are using to browse it. Responsive website design is simply this: a website which is designed to adjust smoothly to fit on desktop browsers, tablets and smartphone browsers. Have you ever opened a website on your tablet or smartphone and it was just a very small version with cluttered navigation and information of what you would see on your computer screen, so you zoomed it and then shrunk and enlarged the pages needed to click on things and read text? Well, that wasn’t a responsive website. A responsive website design looks great on desktop, smartphone and tablets, no matter which device you are using to browse it.
