Accessing DOM Nodes, Measuring & Focusing
Use refs to access DOM nodes, focus inputs after render, and measure element size in a simple, beginner-friendly way.
Why access the DOM?
Goal: Use useRef to reach DOM nodes safely after render.
- Attach ref to a JSX element
- Read ref.current inside effects
- Focus or measure elements
Post-render actions
DOM is available after render. Use useEffect for actions like focus() or measuring size. Keep render pure.
