Target another styled component on hover

Similarly to mxstbr's answer, you can also use interpolation to reference a parent component. I like this route because it encapsulates a component's styling a little better than referencing the child component in the parent.

const Button = styled.button`
  ${Wrapper}:hover & {
    display: none;
  }
`;

I couldn't tell you when this feature was introduced but this works as of v3.

Relevant link: https://www.styled-components.com/docs/advanced#referring-to-other-components

const ConnectButton = styled(WalletDialogButton)`
  background-color: #105b72;
  border: none;
  margin: 10vh auto;
  width: 250px;

  &:hover {
    background-color: #105b72c2;
  }
  `;

This worked for me as Marcos said. I'm using styled() instead of styled.something

I don't really know why, but I'm referencing a node_modules package where WalletDialogButton exists.

As of styled-components v2 you can interpolate other styled components to refer to their automatically generated class names. In your case you'll probably want to do something like this:

const Wrapper = styled.div`
  &:hover ${Button} {
    display: none;
  }
`

See the documentation for more information!

The order of components is important. It will only work if Button is defined above/before Wrapper.

If you're using v1 and you need to do this you can work around it by using a custom class name:

const Wrapper = styled.div`
  &:hover .my__unique__button__class-asdf123 {
    display: none;
  }
`

<Wrapper>
  <Button className="my__unique__button__class-asdf123" />
</Wrapper>

Since v2 is a drop-in upgrade from v1 I'd recommend updating, but if that's not in the cards this is a fine workaround.
