}

Features

• Automatic Conversion: Automatically recognizes and converts color values to rgb(red green blue[ / alpha]) format.
• Named Colors: Converts color values that are equal to CSS named colors (e.g., red, blue, transparent) to their respective RGB values.

Example

Here's an example of how the plugin transforms CSS color values:

/* input */
:root {
    background-color: #ffe;
    color: rgb(0, 0, 0);
    border-color: rgb(240, 240, 240);
    box-shadow: 0 0 0 rgb(114 114 114 / 0%);
}

/* output */
:root {
    background-color: rgb(255 255 238);
    color: black;
    border-color: rgb(240 240 240);
    box-shadow: 0 0 0 transparent;
}
