CSS: text-shadow und box-shadow
Nett:
All browsers that support the CSS text-shadow and box-shadow properties also support the new CSS3 RGBa syntax. Which means you can safely combine them today.
That’s handy, because it means no worrying about matching a precise hex colour shadow to a specific hex colour background. Instead just let the browser blend. An example:
p {
text-shadow: rgba(0, 0, 0, 0.2) 0 1px 0;
}
