Is background-color:none valid in CSS?

One of the most commonly used properties in CSS is the background-color property, which allows you to set the background color for any element on your page.

But did you know none is a valid value for this property or not?

In this blog post, we’ll explore why background-color: none is not valid and what we can use instead.

The none is not a valid value for background-color. According to the CSS 2.1 specification, the background-color property can take either a color keyword, a numerical color value, or the keywords transparent or inherit. Valid color keywords are aqua, black, blue, fuchsia, gray, green, lime, maroon, navy, olive, orange, purple, red, silver, teal, white, and yellow.

Incorrect :

#div {
    background-color: none;
}

Correct :

#div {
    background-color: transparent;
}

Correct :

#div {
    background: none;
}

The CSS property background: none sets the background image to none and the background color to transparent. It is essentially a shorthand property that allows you to set multiple background properties at once.

When you use background: none, you are instructing the browser to not display any background image on the selected element and to set its background color to transparent.

This is different from setting background-color: transparent, which only sets the background color to transparent, while the background image (if any) will still be displayed.
