HTML Block Elements

What is a Block Element?

In the realm of HTML (HyperText Markup Language), understanding the difference between various types of elements is crucial. One fundamental classification is block elements. A block element starts on a new line and takes up the full width available, forming a “block” on the page. They are essential for structuring the layout of web pages.

A. Definition of Block Elements

A block element is defined as an HTML element that generates a new line before and after itself when rendered in a browser. This characteristic allows block elements to stack vertically, forming the layout foundation of a webpage.

B. Characteristics of Block Elements

• Starts on a new line: Block elements do not sit next to other elements.
• Full width: By default, they take up the entire width of their parent container, although this can be changed with CSS.
• Contain inline elements: Block elements can contain other block elements as well as inline elements.
