javascript instance method
String.prototype.big()
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
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
bigis 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:
document.getElementById("yourElemId").style.fontSize = "2em";
