Make sure the color property matches the browser colors, hex codes, and RGB values, as well as any color

Hey there, I've been putting together a custom vue component that includes a color prop.

I want to ensure this color can be matched to all different scenarios it may encounter. The main cases I'm considering include:

  • Standard browser colors like white, black, etc.
  • Hex/RGB color codes (or any other formats browsers can interpret).
  • Custom color variables (for example: var(--pa-primary-accent)

For the first two situations, simply passing the color and utilizing it should suffice. However, for the third case, if a user only provides pa-primary-accent, then I need to append it with var(--${color}). How can I create a solution that accommodates both scenarios seamlessly?

Here's a snippet of the code in question:

// Current implementation, breaks if user passes `white` for example.
computed: {
    style () {
      return `
      background-color: var(--${this.bgColor});
      `
    },

Answer №1

To address this issue, @vrugtehagel suggested a solution involving fallbacks, which I have implemented for all my CSS color properties with success.

For instance:

background-color: var(--${this.bgColor}, ${this.bgColor});

It's important to note that custom -- prefixed values will take precedence over regular values if they have the same name.
