How Can I Effectively Change the Color of an HR Element in CSS?

Customizing the Appearance of an hr Element with CSS

CSS offers a variety of properties to control the appearance of an hr element. One common adjustment is to change its line color, but simply applying the color property may not yield the desired result.

The Challenge of Changing Line Color with 'color' Property

The example code attempting to set hr { color: #123455; } faces a limitation. While color specifies the text color, it does not affect the line produced by the hr tag.

Solution: Utilizing 'border-color' Property

To change the line color effectively, you should employ the border-color property. This targets the border of the line, allowing for customization.

Importance of Specifying Background Color

However, if you adjust the line's size, the border may exceed it, revealing the default background color. To prevent this, consider also setting the background-color property.

Reference Examples

The HTML 5 Boilerplate project includes the following default rule:

hr {
  border-top: 1px solid #ccc;
}

SitePoint's article "12 Little-Known CSS Facts" suggests using border-color: inherit; to match the line color with the parent element.
