 ### Make an icon responsive to theme switch
 
-To make an icon responsive to theme switching, override its
-[`filter` CSS property](https://developer.mozilla.org/en-US/docs/Web/CSS/filter). In this example, we use the
-`--fill-icon-image-card` CSS variable from the `vizro-bootstrap` CSS file. It leverages the `invert()` function to
-flip the icon's color during a theme switch.

 This approach works if your icon initially has a white fill color. If not, modify the SVG code by adding `fill="white"`.
