HTML layout elements help organize the structure of a webpage, making it easier to read, maintain, and style with CSS. Modern HTML uses semantic elements, which describe the purpose of each section.
Common HTML Layout Elements
| Element | Purpose |
|---|---|
<header> | Contains the page or section heading, logo, or navigation. |
<nav> | Holds navigation links. |
<main> | Contains the primary content of the page. |
<section> | Groups related content together. |
<article> | Represents independent content, such as a blog post or news article. |
<aside> | Contains side content like advertisements or related links. |
<footer> | Displays footer information such as copyright or contact details. |
<div> | A generic container used for grouping elements when no semantic element fits. |
