Basic Method: Using the <hr> Tag
One of the easiest ways to add a line is with the <hr> tag. This tag is built into HTML and creates a horizontal rule (a horizontal line) where you place it. It does not need a closing tag. In HTML5, you can write either <hr> or <hr />.
Here is a simple example:
<p>Text above the line.</p>
<hr>
<p>Text below the line.</p>That will display a line between the two paragraphs. The line spans the width of its container by default.
The <hr> tag originally had more decorative attributes (like size, color, align), but those are now deprecated. Instead, CSS styling is recommended.
Customizing the Line with CSS
If you want your line to look unique, you can style it with CSS. This gives you full control over color, thickness, width, and style.
Example CSS styling
hr {
border: none; /* remove default border */
border-top: 2px solid #555; /* make a solid line */
width: 80%; /* line width 80% of container */
margin: 20px auto; /* vertical margin, centered */
}
You can also create dashed or dotted lines:
hr.dashed {
border-top: 1px dashed #888;
}
Or make a thick line:
hr.thick {
border-top: 5px solid #333;
}
If you want a shorter line (not full width):
<hr style="width: 50%; margin-left: 0;">
This places the line aligned to the left.
Alternative Method: Using a <div> or Other Element
Sometimes designers prefer using a <div> or another element as a line, especially when more control is needed (like gradients, animations, or special shapes). Here's how:
<div class="my-line"></div>
.my-line {
height: 2px;
background-color: #444;
width: 100%;
margin: 30px 0;
}This method is more flexible for creative designs, though the <hr> tag is more semantic for a simple visual break.
When to Use Which Method
| Method | Best Use Case | Advantages | Notes / Limitations |
| <hr> tag | Simple visual breaks in content | Built-in, semantic, easy to use | Styling less flexible by itself |
| <hr> + CSS styling | When you want control over color, size, etc. | Combines semantic tag with visual design | Requires CSS understanding |
| <div> with CSS | For advanced styling, animations, or effects | Full control over style, shape, behavior | Not semantic as a line tag |
Tips and Best Practices
- Do not use <hr> just for spacing or layout. It’s meant to represent a thematic break or separation in content.
- Use CSS for styling, not deprecated HTML attributes.
- Keep your lines consistent in your design (same color, thickness) to maintain visual harmony.
- Use responsive units (%, em, rem) for width so the line adapts to different screen sizes.
- If you need animated or decorative lines (gradient, fade-in, etc.), use CSS or CSS + JavaScript on a <div> or styled <hr>.
- Test your lines on different screen sizes (desktop, tablet, mobile) to ensure they look good everywhere.
Sample Full HTML Page
Here’s a simple example combining methods:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1">
<title>Line Example</title>
<style>
.custom-line {
border: none;
border-top: 3px solid #0066cc;
width: 60%;
margin: 30px auto;
}
.my-div-line {
height: 4px;
background: linear-gradient(to right, #0066cc, #00ccff);
width: 50%;
margin: 40px auto;
}
</style>
</head>
<body>
<h1>Hello World</h1>
<p>Intro text above the first line.</p>
<hr>
<p>Some middle content.</p>
<hr class="custom-line">
<div class="my-div-line"></div>
<p>More content after the decorative line.</p>
</body>
</html>This shows a default line, a styled <hr>, and a <div> line together.
