A section is an element of design layout that divides a web page into visually distinct segments. HTML uses <section> tags to create them. Each segment forms a distinct block that helps establish a visual hierarchy and organizes content on the site. This approach makes the site’s structure more intuitive and user-friendly, effectively guiding visitors through the content.
For example, a hotel chain's home page might contain different sections, such as a header with the hotel's logo, the website menu, and a booking button. Below the header will likely be a section with room types, images, and descriptions. Further down the page, another section highlights testimonials and customer reviews.
Each website section serves a unique purpose and houses related content. Dividing pages into sections helps users find what they’re looking for by improving the site's appearance and usability.
