CSS applies to any career that involves web development. Web designers create the templates, mockups, and styles for a website using HTML and CSS that web developers use to build websites. Front-end web developers use CSS with HTML and JavaScript to build front-end web applications that run in the browser. Fullstack web developers create both the part of a web application that runs in the browser and on the server and need to know CSS to make the front-end look good. Content managers may need to know CSS to apply custom styles to articles they publish through a content management system like WordPress. Other job titles that may require you to know CSS include junior web developer, social media manager, website editor, content editor, website project manager, website support specialist, and webmaster.
