Difference Between Inline and Block-level Elements in HTML

Inline elements in HTML are displayed within the flow of the document, with no line breaks before or after the element. They only take up as much width as necessary and cannot have height or width set. Examples of inline elements include <span>, <a>, and <img>.

Block-level elements in HTML, on the other hand, create a line break before and after the element and take up the full width available. They can have height and width set and can contain other block-level or inline elements. Examples of block-level elements include <div>, <h1> - <h6>, and <p>.

When to use each type of element depends on the desired layout and structure of the webpage. Inline elements are useful for small pieces of content like text or links within a paragraph, while block-level elements are used to create sections of content that need to be visually separated or styled differently.
