The duties of an entry-level HTML developer involve creating websites or website content and performing user-facing design tasks using hypertext markup language (HTML). As an HTML developer, you may also use CSS or other web-centered design languages, such as JavaScript. Your responsibilities in this role often include testing existing HTML code for accuracy and quality or creating specific aspects of a website or user interface, such as dropdown menus or other interactive user-facing elements. Some employers refer to jobs that use HTML for web development as front-end developer jobs. Many entry-level jobs in other fields use basic HTML coding, but this title refers to jobs in which coding is your primary duty.
