A full stack developer is someone who works with both the front end and back end of a web application. The front end is responsible for the visual look and feel of the website, while back end is responsible for the behind the scenes logic and infrastructure of the site.

Front end Development (Client side)

Everything on a web page from the logo, to the search bar, buttons, overall layout and how the user interacts with the page was created by a front end developer. Front end developers are in charge of the look and feel of the website.

Front end developers also have to make sure the website looks good on all devices (phones, tablets, and computer screens). This is called Responsive Web Design.

Back end Development (Server side)

Back end development refers to the part of the application that the user does not see. Back end developers focus on the logic of the site, creating servers, and working with databases and API's (Application Programming Interfaces).

For example, the content and layout for a form would be created on the client side, but when the users submits their information it gets processed on the server side (back end).

HTML

HTML stands for HyperText Markup Language. HTML displays the content on the page like buttons, links, headings, paragraphs, and lists.

CSS

CSS stands for Cascading Style Sheets. CSS is responsible for the style of your web page including colors, layouts, and animations.

JavaScript

You use JavaScript with HTML and CSS to create dynamic and interactive web pages and mobile applications
