过时
This feature is obsolete. Although it may still work in some browsers, its use is discouraged since it could be removed at any time. Try to avoid using it.

过时 HTMLFontElement.size 特性为 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 属性在 <basefont> 元素。

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

Microsyntax	描述	范例
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` 属性在 `<basefont>` element (the result should be in the same range of 1-7)	`+2 -1`

句法

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

范例

// Assumes there is <font id="f"> element in the HTML
var f = document.getElementById("f");
f.size = "6";

规范

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


								<font>.size
