HTMLFontElement.size

Deprecated: This feature is no longer recommended. Though some browsers might still support it, it may have already been removed from the relevant web standards, may be in the process of being dropped, or may only be kept for compatibility purposes. Avoid using it, and update existing code if possible; see the compatibility table at the bottom of this page to guide your decision. Be aware that this feature may cease to work at any time.

The obsolete HTMLFontElement.size property is a DOMString that reflects the size HTML attribute. It contains either an integer number in the range of 1-7 or a relative value to increase/decrease the value of the size attribute of the <basefont> element.

The format of the string must follow one of the following HTML microsyntaxes:

Microsyntax	Description	Examples
Valid size number string	integer number in the range of 1-7	`6`
Relative size string	+x or -x, where x is the number relative to the value of the `size` attribute of the `<basefont>` element (the result should be in the same range of 1-7)	`+2 -1`

Syntax

sizeString = fontObj.size;
fontObj.size = sizeString;

Examples

// Assumes there is <font id="f"> element in the HTML

var f = document.getElementById("f");
f.size = "6";

Specifications

The <font> tag is not supported in HTML5 and as a result neither is <font>.size.
