Div Block
The 'div' element in HTML is a block-level container used to group together and structure other HTML elements. It does not inherently represent anything, but it can be used alongside CSS to style or layout a section of a webpage. Div blocks are extremely versatile and are often used to create grids, columns, or sections within a page. They can be styled using CSS to have specific sizes, colors, backgrounds, and positioning. The 'div' element is a fundamental part of web design and development, providing a way to organize and manipulate content on a webpage effectively.
