An application is always judged by how it looks. Now that we know how to make it perform, we need to learn how to make it look good. Nowadays, it is common practice to build the frontend while keeping the following two things in mind:

Responsive: This style of programming makes your site usable everywhere, no matter how big the screen is. The HTML markup will always adapt depending on the width of the screen.
