attr

The attr CSS function is supported in a basic capacity. I will be adding more features, but PRs are welcome.

/* get value from `width` prop */
width: attr(width vw);

/* specify type or unit to apply to value */
width: attr(width vw);

/* fallback value if props.width is falsey */
width: attr(width vw, 50);

const H1 = styled.h1`
  font-size: attr(fontSize px);
  margin: attr(margin rem, 4);
  font-family: sans-serif;
  color: ${colors.pink[5]};
  @media (min-width: 680px) {
    color: attr(desktopColor);
  }
`

const Title = ({ title, scale }) => {
  return (
    <H1 fontSize={16 * scale} desktopColor={colors.gray[5]}>
      {title}
    </H1>
  )
}
