Is `background-color: none` a valid CSS property?

Validity of background-color:none in CSS

The question arises regarding the validity of the following CSS code:

<code class="css">.class {
    background-color:none;
}</code>
Copy after login

To resolve this, it is necessary to consult the CSS 2.1 specification, which defines the permissible values for the background-color property as:

  • transparent
  • inherit

can be represented by a keyword (e.g., blue, red) or a numerical color code. The valid color keywords are:

aqua, black, blue, fuchsia, gray, green, lime, maroon, navy, olive,
orange, purple, red, silver, teal, white, and yellow
Copy after login

Therefore, as none is not included in these lists, it is not a valid value for the background-color property. The intended effect, a transparent background, can be achieved by using the transparent keyword instead.
