Using the HTML `<hr>` Element to Create Thematic Breaks
Understanding Thematic Breaks
The HTML `<hr>` (horizontal rule) element is used to create a thematic break in a webpage. It signifies a shift in topic or section. While visually it’s often rendered as a horizontal line, its primary purpose is to add semantic meaning and structure to the webpage, improving readability and user experience. It is not just about visual appearance; it's about logically separating blocks of content.
Using the `<hr>` Element
The `<hr>` element is an empty element (it has no closing tag). It's typically placed between paragraphs or sections to visually separate content. Here’s a simple example:
