Building a custom checkbox in React

The guide provides a comprehensive tutorial on creating a custom checkbox in React while maintaining accessibility for assistive technology. It explains the difference between default and custom checkboxes, the importance of using controlled inputs in React to manage form controls, and the steps to create a checkbox component. The tutorial emphasizes making the checkbox a controlled input by using React's `useState` hook to manage its state, thereby ensuring the state is the only source of truth. It details styling techniques for checkboxes using modern CSS properties like `appearance: none;` to remove default browser styles and create a consistent look across different browsers. The guide also covers handling multiple checkboxes, managing their state, and ensuring accessibility by using ARIA attributes if replacing native inputs. The tutorial culminates in a practical example of a to-do list application, demonstrating how to render and manage multiple checkboxes interactively.
