HTML Div Tag
The HTML Div Tag <div> is a generic container used to group HTML elements. It is invisible by itself but becomes a powerful styling and layout tool when combined with CSS. The <div> tag is the most commonly used element for organizing web pages.
What is the Div Tag?
- The
<div>tag is a block-level generic container. - It has no visual style by default — only structure.
- Used to group elements and apply common CSS styles.
- Can be nested to create complex layouts.
