Which HTML tag is commonly used to create a line break?

The tag used to create a line break in HTML is the <br> tag. This tag is an empty element that does not have a closing counterpart and is used specifically to insert a line break in the text. For example, if you want to space out lines of text within a paragraph or ensure that content appears on a new line without starting a new paragraph, the <br> tag is the appropriate choice.

In contrast, the <p> tag is designed to define entire paragraphs of text, adding space above and below the paragraph, rather than just creating a simple line break. The <hr> tag is used to create thematic breaks in content, typically represented as a horizontal line, while the <div> tag is a block-level element used for grouping and structuring larger sections of HTML, often accompanied by styling or scripting rather than for creating line breaks.
