When you’re building a webpage, understanding the purpose of different HTML elements can make a huge difference. Elements like <header>, <footer>, <nav>, <section>, and <article> aren’t just there to hold content—they each have a specific meaning and purpose. But how do these elements differ from the general-purpose <div> tag. The <header> element represents the top section of a webpage or section of content. Think of it as the introduction. It typically contains navigation menus, logos, titles, or a search bar. Using a <header> tag makes it clear that this part of the page is an introduction or top section. This helps both search engines and screen readers understand the structure of your page.
A <div> could also be used to wrap this content, but a <div> doesn’t tell anyone (or anything) that this is an introductory section. It’s just a generic container. So, <header> is more meaningful.
