There is not a Transparent color code, but there is an Opacity styling. Check out the documentation about it over at developer.mozilla.org. You will probably want to set the color of the element and then apply the opacity to it. background-color: #ffffff; opacity: .4;

You can't code transparency as pure RGB (which stands for red-green-blue channels), but you can use the RGBA notation, in which you define the color + alpha channel together: color: rgba(255, 0, 0, 0.5); /* red at 50% opacity */. If you want "transparent", just set the last number to 0, regardless of the color.
Apr 21, 2014 · Maximal value (255 dec, FF hex) means fully opaque. Minimum value (0 dec, 00 hex) means fully transparent.

Given a transparency percentage, for example 20%, you know the opaque percentage value is 80% (this is 100-20=80) The range for the alpha channel is 8 bits (2^8=256), meaning the range goes from 0 to 255. Project the opaque percentage into the alpha range, that is, multiply the range (255) by the percentage. In this example 255 * 0.8 = 204.
Dec 8, 2016 · Here's an example showing that the alpha value is genuinely correct in the returned color: static Color SetTransparency(int A, Color color) return Color.FromArgb(A, color.R, color.G, color.B); static void Main() Color halfTransparent = SetTransparency(127, Colors.Black);
