Explanation
The value rgba(255, 255, 255, 0.0) represents a color in the RGBA color model. Let's break down the components:
'255, 255, 255': The first three values (red, green, and blue) represent the RGB components of the color. In this case, all three components are set to their maximum value of 255, resulting in the color white.
'0.0': The fourth value represents the alpha channel, which controls the transparency of the color. The alpha channel ranges from 0.0 (completely transparent) to 1.0 (completely opaque). In this case, the alpha channel is set to 0.0, indicating that the color is fully transparent
