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 |
