String.prototype.big()

{{Deprecated_Header}}

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

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

Syntax#

big()

Parameters#

None.

Return value#

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

Examples#

Using big()#

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

const contentString = "Hello, world";

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

This will create the following HTML:

<big>Hello, world</big>

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

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

document.getElementById("yourElemId").style.fontSize = "2em";
