String.prototype.big()

Deprecated

Avoid using this feature in new projects. HTML wrapper methods exist only for backwards compatibility. Use DOM APIs to create elements instead. This feature may be a candidate for removal from web standards or browsers.

Consider using the following features instead: DOM.

The big() method of String values creates a string that embeds this string in a <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

js
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:

js
const contentString = "Hello, world";

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

This will create the following HTML:

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 font-size through the element.style attribute:

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