An integer between 1 and 7, or a string representing a signed integer between 1 and 7.
A string beginning with a
<font size="size"> start tag (double quotes in
size are replaced with
"), then the text
str, and then a
</font> end tag.
fontsize() method itself simply joins the string parts together without any validation or normalization. However, to create valid
<font> elements, When you specify size as an integer, you set the font size of
str to one of the 7 defined sizes. You can specify
size as a string such as
"+3" to adjust the font size of
str relative to 3, the default value.
The code below creates an HTML string and then replaces the document's body with it:
const contentString = "Hello, world"; document.body.innerHTML = contentString.fontsize(7);
This will create the following HTML:
<font size="7">Hello, world</font>
Warning: This markup is invalid, because
font is no longer a valid element.
document.getElementById("yourElemId").style.fontSize = "7pt";
