String.prototype.fixed()

{{Deprecated_Header}}

The fixed() method of {{jsxref("String")}} values creates a string that embeds this string in a {{HTMLElement("tt")}} element (<tt>str</tt>), which causes this string to be displayed in a fixed-width font.

[!NOTE] All HTML wrapper methods are deprecated and only standardized for compatibility purposes. For the case of fixed(), the <tt> element itself has been removed from the HTML specification and shouldn't be used anymore. Web developers should use CSS properties instead.

Syntax#

fixed()

Parameters#

None.

Return value#

A string beginning with a <tt> start tag, then the text str, and then a </tt> end tag.

Examples#

Using fixed()#

The code below creates an HTML string and then replaces the document's body with it:

const contentString = "Hello, world";

document.body.innerHTML = contentString.fixed();

This will create the following HTML:

<tt>Hello, world</tt>

[!WARNING] This markup is invalid, because tt is no longer a valid element.

Instead of using fixed() and creating HTML text directly, you should use CSS to manipulate fonts. For example, you can manipulate {{cssxref("font-family")}} through the {{domxref("HTMLElement/style", "element.style")}} attribute:

document.getElementById("yourElemId").style.fontFamily = "monospace";
