Responsive web design is a web development approach that creates dynamic changes to the appearance of a website, depending on the screen size For example, on a phone, users would see content shown in a single column view; a tablet might show the same content in two columns.

Today, many people access websites from mobile devices, rather than desktop computers or laptops. While most smartphones can display regular websites, the content is difficult to read and even harder to navigate. Therefore, many web developers now use responsive web design to provide a better web browsing experience on small screens.

There are several ways to implement responsive web design. One method is to dynamically detect the user's platform (such as an iPad or iPhone) and load specific HTML and CSS for the corresponding device. Another option is to use media queries, which automatically load different CSS styles depending on the size of the browser window. The Bootstrap package, which contains several prewritten JavaScript and CSS files, is based on media queries and is commonly used in responsive web design.

Responsive design will optimize your browsing experience by creating a responsive and flexible web page, optimized for the device that is accessing it. There are many advantages of having a responsive website in today’s digital business. Some of these advantages are as illustrated below:

• Increase your visibility in the search engines
• Save time and cost on mobile development
• Save cost and time on website management
