The alpha channel is a color component that represents the degree of transparency (or opacity) of a color (i.e., the red, green and blue channels). It is used to determine how a pixel is rendered when blended with another.

How do I make Rgba transparent?

Changing the opacity of the background color only To achieve this, use a color value which has an alpha channel—such as rgba. As with opacity , a value of 1 for the alpha channel value makes the color fully opaque. Therefore background-color: rgba(0,0,0,. 5); will set the background color to 50% opacity.
