I was using Heroicons in a Next.js app and they conveniently package the icons as React components.

One thing I wanted to do was customize the stroke width, so they rendered thinner.

I looked how to do that within the JSX, maybe with a prop, but I couldn’t find a way.

I could import the SVG directly from the site, but I liked the React components approach.

For some reason I assumed setting a global CSS property directly didn’t work, as it was hardcoded in the SVG, but it actually worked:

svg path {
  stroke-width: 1;
}
