CSS specificity hierarchy

CSS specificity hierarchy listed from highest to lowest priority:

  1. Inline Styles: These are styles applied directly to an element using the style attribute.

    • Example: <div style="color: red;">

  2. ID Selectors: These are styles applied using the ID of an element, which is unique within a page.

    • Example: #header { color: blue; }

  3. Class Selectors, Attribute Selectors, and Pseudo-classes: These include styles applied using class names, attributes, and pseudo-classes.

    • Examples:
      • Class: .main { color: green; }
      • Attribute: [type="text"] { color: yellow; }
      • Pseudo-class: :hover { color: purple; }

  4. Element Selectors and Pseudo-elements: These are styles applied directly to HTML elements and pseudo-elements.

    • Examples:
      • Element: p { color: black; }
      • Pseudo-element: ::after { content: ""; }

  5. Universal Selector and Inherited Styles: These styles have the lowest specificity and include the universal selector * and inherited styles from parent elements.

    • Examples:
      • Universal: * { color: gray; }
      • Inherited styles are those passed from parent elements to their children.

Understanding this hierarchy helps in determining which styles will be applied when there are conflicting rules.

useCallback hook in React

`useCallback` is a useful hook for optimizing performance in React applications by preventing unnecessary re-creations of functions. However, you should use it wisely, as it can add complexity and may not always offer a performance improvement in every case. ### 1. **What does `useCallback` do?** `useCallback` returns a memoized version of the callback function that only changes if one of the dependencies has changed. It’s primarily used when passing a function as a prop to child components or using it in an effect (like `useEffect`), where unnecessary re-creations of the function can lead to performance problems. ### 2. **Syntax:** ```javascript const memoizedCallback = useCallback(() => {   // Your callback code }, [dependencies]); ``` - The first argument is the function you want to memoize. - The second argument is an array of dependencies (like `useEffect`). The function will only be re-created if any of these dependencies change. ### 3. **When to use `useCallback`?** You shoul
