CSS 3.0 Valid Color Property

marcel ethan177002-Apr-2013

Hi All!

Visual Studio 2012 (Ultimate) states (with a red squiggly) that

rgba(255, 255, 255, 0.4) is not a valid color property value

But the W3C says it is. Is this a bug, or am I missing something?

Thanks in advance!

Hi Marcel!

Try this way

It is a valid color property as per CSS3 standards;

rgba(255, 255, 255, 0.4)

The fourth parameter 0.4 refers to the opacity which is a CSS3 feature, and a in rgba means alpha

You could also try this in Visual Studio to see that it doesn't flag an error;

rgb(255, 255, 255);
