*HTML Block-Level Elements*



HTML elements are categorized into two main types: block-level elements and inline elements. Block-level elements create a new block or section on the page, typically starting on a new line and taking up the full width available.

Characteristics of Block-Level Elements

  • Start on a new line.
  • Stretch to take up the full width of their parent container.
  • Can contain other block-level and inline elements.
  • Help structure the webpage into meaningful sections.
