HR Element: Thematic Break in Content
The <hr> HTML element is used to insert a thematic break or horizontal rule in a webpage, typically representing a shift in topic or a division between sections of content. It is a void element, meaning it does not have a closing tag, and is often rendered as a horizontal line across the page. The <hr> element provides a visual cue to users that there is a separation in content, making it easier to distinguish between different sections or topics.
Usage and Characteristics
The <hr> element is useful for enhancing the readability and organization of content on a webpage. It can be styled using CSS to change its appearance, such as altering its width, height, color, or style (e.g., solid, dashed, or dotted). Here is an example of how the <hr> tag can be used:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Horizontal Rule Example</title>
<style>
hr {
border: 0;
height: 2px;
background-color: #ccc;
}
</style>
</head>
