Is there a color code for transparent in HTML?

Question

I\'m building a new website, and I\'m looking for a transparent navigation bar so the background is visible.

Answer 1

You can specify value to background-color using rgba(), as:

.style{
        background-color: rgba(100, 100, 100, 0.5);
}

0.5 is the transparency value

0.5 is more like semi-transparent, changing the value from 0.5 to 0 gave me true transparency.
