String.prototype.fixed()

Thefixed() method ofString values creates a string that embeds this string in a<tt> element (<tt>str</tt>), which causes this string to be displayed in a fixed-width font.

Note:AllHTML wrapper methods are deprecated and only standardized for compatibility purposes. For the case offixed(), the<tt> element itself has been removed from the HTML specification and shouldn't be used anymore. Web developers should useCSS properties instead.

Syntax

js
fixed()

Parameters

None.

Return value

A string beginning with a<tt> start tag, then the textstr, 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:

js
const contentString = "Hello, world";document.body.innerHTML = contentString.fixed();

This will create the following HTML:

html
<tt>Hello, world</tt>

Warning:This markup is invalid, becausett is no longer a valid element.

Instead of usingfixed() and creating HTML text directly, you should use CSS to manipulate fonts. For example, you can manipulatefont-family through theelement.style attribute:

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