CSS Styles Not Applying to Custom Checkbox Input in React with Styled Components

I'm sure I'm missing something obvious here, but I'm currently working on a React application using Styled Components, and I've run into a perplexing scenario. I'm trying to style a custom checkbox input, but the styles seem to be ignored when the input is checked. The checkbox input has a default appearance that doesn't change even though I'm applying styles based on the state. Here's a simplified version of my code: ```javascript import styled from 'styled-components'; const Checkbox = styled.input` display: none; `; const CustomCheckbox = styled.label` display: inline-block; width: 20px; height: 20px; background-color: #f0f0f0; border: 2px solid #ccc; cursor: pointer; ${Checkbox}:checked + & { background-color: #007bff; border-color: #0056b3; } `; function App() { return ( <div> <Checkbox type="checkbox" id="custom-checkbox" /> <CustomCheckbox htmlFor="custom-checkbox" /> </div> ); } ``` When I check the checkbox, I expected the background color of the `CustomCheckbox` to change, but it doesn’t seem to reflect the checked state. I’ve verified that the checkbox is indeed being checked, as I can see it in the inspector. I've also tried debugging by adding `!important` to the styles, but that has not resolved the scenario. My Styled Components version is 5.3.0, and I’m using React 17.0.2. Has anyone encountered a similar scenario or know why the styles for the checked state are not applying correctly? This is part of a larger API I'm building. What am I doing wrong?
