I'm customizing a plugin that uses css3's rgba throughout, i'm trying to figure out how to toggle it for it to render white with the opacity. At default it's near the shade of #333 , and my attempts area leading it to blue or brown. Why are there white customization numbers? below is what I'm using?

background:rgba(255,255,255, 0.3);

The code you have is white with low opacity

If something white with a low opacity is above something black, you end up with a lighter shade of gray. Is there a red above it? Lighter red, etc. That's how opacity works

Here is a simple demo .

If you want to make this more white make it less opaque

background:rgba(255,255,255, 0.9);
