HTML is the foundation of every website on the internet. Whether you’re applying for a front-end developer position, a full-stack development role, or an internship, understanding HTML fundamentals is essential. Employers frequently include HTML interview questions to evaluate a candidate’s knowledge of webpage structure, semantic markup, accessibility, and best coding practices.
Although HTML is considered one of the easiest web technologies to learn, interviewers often ask practical and conceptual questions to determine whether candidates understand how HTML works beyond basic syntax.
This guide covers common HTML interview questions, explains key concepts, and provides useful preparation tips for beginners and experienced developers.
