This is how your end users interact with the design itself. It works with the Backend to make the website look a specific way. It’s built using coding languages such as HTML, CSS, JavaScript and jQuery. An easier way to imagine it is as if your website was a brick and mortar shop - the front of the shop (outside) is front end design, then you have inside the shop with the counter and till directing users to it (as front end development) and finally the back of the shop where all the products sit is the backend.
