Question

Is there a way to create a linear-gradient background using variables for color names, angles, and other properties?

I've been encountering a recurring issue where I need to dynamically set the background of different elements within my component as linear gradients. Specifically, I'm working on creating a grid background that adjusts and scales based on various inputs.

What I'm aiming to do is construct my CSS linear-gradient background property in a function. Here's a simplified example of what I'm attempting:

createBackgroundString(){
    return 'linear-gradient(' + this.angle + 'deg, ' + this.color1 + ', ' + this.color2 + ')';
}

Once I have this string, my goal is to insert it into the :style attribute so that Vue can apply it dynamically:

v-bind:style="{ background: createBackgroundString() }"

Unfortunately, Vue doesn't accept this approach and simply ignores it. It seems that the resulting string is too complex for the template property which expects simple strings like 'red' or '#FF0000'.

Is there any clever workaround or hack to achieve this functionality in Vue? Currently, I'm forced to fall back on using jQuery for this task, which is less than ideal.

Here is one way to make it work:

<div :style="{ backgroundImage: createBackgroundString }" />

Also, you can create a computed property like this:

data() {
    return {
      angle: '50',
      color1: 'red',
      color2: 'blue'
    }
  },
  computed: {
    createBackgroundString() {
      return `linear-gradient(${this.angle}deg, ${this.color1}, ${this.color2})`;
    }
  }

If you prefer not to use backticks (`), that's totally fine too.

Just a small note: I changed createBackgroundString() to createBackgroundString
