Template:Hr/doc

{{Hr}} displays a horizontal rule (horizontal line) which by default looks like this:

---

and whose height can be adjusted if desired. The rule appears on a line of its own, creating a line break if used mid-paragraph.

Usage

For the default appearance, insert {{hr}} where you want the horizontal rule to appear. Text before {{hr}} will appear above the rule, and text after it below.

To change the rule's height, use {{hr|height}}, where height is the thickness in pixels: for example {{hr|2}} creates a rule two pixels high.

• The height value need not be a whole number.
• To make the rule thicker (taller) than the default, use a value greater than 1.
• To make it thinner than the default, use a value between 0 and 1, exclusive.
• On lower-resolution displays:
  • Small height differences might render the same.
  • A height less than 1 might render nothing (an "invisible line").
    • For any given device, a visible line might become invisible, or vice versa, depending on what precedes it on the page. Thus, unrelated edits can affect the rendering.
  • All of these effects were seen on a Windows laptop display, at 1366x768 resolution, in AD 2025. For these reasons, a height less than 1 is not recommended. See Examples and testing for the current renderings on your particular device.
• Enter just the number; don't add a unit such as px or em after it.
• Placing the template within a line of text,

like {{hr}} this,

will split the text at the rule,

like

this

Examples and testing

Rendering varies slightly depending on display resolution; see Usage.

Coding	Resulting line height on your display, today
{{hr|0.5}}
{{hr|1}} or {{hr}}
{{hr|1.5}}
{{hr|2}}
{{hr|2.5}}
{{hr|3}}
{{hr|4}}
{{hr|5}}
{{hr|10}}

(At this point, we have a horizontal bar, not a horizontal rule. Some judicious restraint is recommended, making the line height proportional to [not equal to] that of the nearby text. {{hr|10}} is excessive for most uses.)

Alternatives

A horizontal rule with the default appearance can also be produced by

• typing four hyphens ---- on a new line, or by
• using an HTML <hr /> tag.

The template inserts the HTML tag and gives it a style= attribute if the height is specified. For example, {{hr|3}} adds <hr style="height:3px" /> to the HTML for the page.
