target child element styled components - reactjs

Question

I'm trying to change the nth-child(2) background color of the ColorBox element by targeting it as a child of ImgGrid but I just can't seem to get it to work, I have tried multiple variations with different elements and nothing seems to be working
This will change the background color if I don't try to target an nth-child element
const ImgGrid = styled.div`
display: flex;
flex-wrap: wrap;
flex-direction: row;
${ColorBox} {
background: #ff00ff;
}
`
How can I target the nth-child(2) of the ColorBox element?
import React from 'react'
import styled from 'styled-components'
// import Img from '../../atoms/Img'
import { array, bool } from 'prop-types'
const Wrap = styled.div`
padding: 20px 0;
`
const BoxWrap = styled.div`
position: relative;
border: 1px solid #000;
height: auto;
padding: 20px;
`
const Title = styled.div`
position: absolute;
display: flex;
align-items: center;
top: -20px;
left: 50%;
-webkit-transform: translateX(-50%);
transform: translateX(-50%);
height: 40px;
background: #f6f6f6;
padding: 10px;
`
const BoxInner = styled.div`
width: 100%;
height: 100%;
`
const ColorBox = styled.div`
height: 60px;
width: 100%;
background: #FFD700;
`
const ImgCell = styled.div`
flex: 0 0 25%;
padding: 5px;
`
const ImgGrid = styled.div`
display: flex;
flex-wrap: wrap;
flex-direction: row;
&:nth-child(2) ${ColorBox} {
background: #ff00ff;
}
`
const ImgCellInner = styled.div`
position: relative;
`
// const ImgText = styled.div`
// position: absolute;
// bottom: 0;
// left: 0;
// padding: 5px;
// width: 100%;
// background: rgba(0,0,0,0.7);
// color: #fff;
// `
const ImgWrap = styled.div`
width: 100%;
`
const ColorWrap = styled.div`
`
const Filter = ({ filterData, color }) => (
<Wrap>

I can assume your code is not working because &:nth-child(2) means you are selecting ImgGrid which is second child itself. Try to specify ImgCell as nth-child(2):
const ImgGrid = styled.div`
display: flex;
flex-wrap: wrap;
flex-direction: row;
${ImgCell}:nth-child(2) ${ColorBox} {
background: #ff00ff;
}
`
I'm not sure about scoping, so probably you need to use & before:
const ImgGrid = styled.div`
display: flex;
flex-wrap: wrap;
flex-direction: row;
& ${ImgCell}:nth-child(2) ${ColorBox} {
background: #ff00ff;
}
`

If you stumble on this question looking for how to target all children elements, here is how;
const ParentDiv = styled.div`
>* {
background: white;
padding: 5px;
};
/* ...etc */
`;

I had the same problem. :focus-within in parent element worked for me, could solve your problem too.
Eg:
export const Parent = styled.div`
display: flex;
align-items: center;
border: 1px solid #000;
&:focus-within {
border: 1px solid #2ADCC6;
}
`;
export const Child = styled.input`
flex: 1;
border: none;
`;
