The foundation of front-end development is HTML and CSS. Every web page on the Internet is written in one of these languages. You will learn all you need to know about HTML and CSS in our curriculum, from the very fundamentals to more complex ideas. There are two components to every online or mobile application: a front-end and a back-end. The user interacts with and sees the front-end. Your phone's app or the website you go to are examples. Therefore, creating stunning, dynamic user interfaces is the responsibility of front-end engineers.
