CSS relative color syntax

CSS relative color syntax is a powerful feature that allows you to create new colors based on the channels and values of another color. It uses the "from" keyword to indicate the originating color and then converts it to the specified color space. The resulting color can be modified by adjusting the variables, such as lightening or darkening the color, saturating or desaturating it, adjusting opacity, inverting or complimenting it, and more.

Some use cases and demonstrations of CSS relative color syntax include lightening a color by increasing the lightness channel, darkening a color by decreasing the lightness channel, saturating a color by increasing the saturation channel, desaturating a color by decreasing the saturation channel, adjusting the opacity of a color by modifying the alpha channel, inverting a color by inverting all the channels, and complimenting a color by rotating the hue.

Overall, CSS relative color syntax provides a flexible and efficient way to create new colors based on existing ones, offering a wide range of possibilities for color adjustments and customization in web design.
