Back end and front end describe website program interfaces relative to the user.
The front end of your website is how it looks and how a user interacts with it: the graphic design and HTML portionâ€”some people call this the user interface or UI.
In contrast, the back end handles the dynamic parts of the site, that your website visitors generally donâ€™t see or interact with such as a newsletter, an administration page, a registration database, a contact page or more complicated web applications.
Your back end interfaces with your UI and makes your website work. If youâ€™re looking for more on how to create your small business or startupâ€™s first website, start with this guide.
