Welcome to The Coding College, your ultimate destination for learning web development concepts. In this post, we’ll explore RGB and RGBA Colors in HTML, explaining how to use them effectively to create stunning designs.
What Are RGB and RGBA Colors?
- RGB (Red, Green, Blue) colors represent the intensity of red, green, and blue light, ranging from 0 to 255 for each color.
- RGBA is an extension of RGB that includes an alpha channel to control transparency (opacity), with values ranging from 0.0 (fully transparent) to 1.0 (fully opaque).
