How do I put gradient on thin icons?

Hi,

From what I read in Gradients in SVG - SVG: Scalable Vector Graphics | MDN, you must add <linearGradient> to the SVG.

Others resources:

What you can do is create a hidden SVG in your theme/component to define your gradients:

<svg aria-hidden="true" focusable="false" style="width:0; height:0; position:absolute;">
  <linearGradient id="my-gradient-1" x2="0" y2="1">
    <stop offset="0%" stop-color="var(--color-stop-1)" />
    <stop offset="50%" stop-color="var(--color-stop-2)" />
  </linearGradient>
  
  <linearGradient id="my-gradient-2">
    <stop offset="0%" stop-color="var(--color-stop-1)" />
    <stop offset="50%" stop-color="var(--color-stop-2)" />
    <stop offset="100%" stop-color="var(--color-stop-3)" />
  </linearGradient>

  <!-- Define specific gradient as needed with a unique ID -->
</svg>

Then, in your CSS, you define the color, and you target what SVG elements you want to fill:

/* defines gradients color */
#my-gradient-1 {
    --color-stop-1: #a770ef;
    --color-stop-2: #eda58b;
}

#my-gradient-2 {
    --color-stop-1: #2980b9;
    --color-stop-2: #6dd5fa;
    --color-stop-3: #ffffff;
}

.svg-icon, .svg-icon-title {
    /* targets all svg icons */
    fill: url(#my-gradient-1) var(--header_primary-low-mid);
    
    /* targets only chat icon */
    &.d-icon-d-chat {
        fill: url(#my-gradient-2) var(--header_primary-low-mid);
    }
}

Note: the second value of fill is a fallback color.

I did not test extensively; this is an example of how you can customize.
Feel free to check the documentation to make more complex gradients.

I hope that helps!
