color

A string expressing the color as a hexadecimal RGB triplet or as a string literal. String literals for color names are listed in the CSS color reference.

A string beginning with a <font color="color"> start tag (double quotes in color are replaced with "), then the text str, and then a </font> end tag.

The fontcolor() method itself simply joins the string parts together without any validation or normalization. However, to create valid <font> elements, if you express color as a hexadecimal RGB triplet, you must use the format rrggbb. For example, the hexadecimal RGB values for salmon are red=FA, green=80, and blue=72, so the RGB triplet for salmon is "FA8072".

The code below creates an HTML string and then replaces the document's body with it:

const contentString = "Hello, world";

document.body.innerHTML = contentString.fontcolor("red");

This will create the following HTML:

<font color="red">Hello, world</font>

Instead of using fontcolor() and creating HTML text directly, you should use CSS to manipulate fonts. For example, you can manipulate color through the element.style attribute:

document.getElementById("yourElemId").style.color = "red";
