<h2>Understanding Core Web Vitals</h2><p>Google's Core Web Vitals are essential metrics that measure real-world user experience on your website. These three metrics are:</p><h3>1. Largest Contentful Paint (LCP)</h3><p>LCP measures the time it takes for the largest content element to become visible. Aim for 2.5 seconds or less.</p><h3>2. First Input Delay (FID)</h3><p>FID measures the responsiveness of your page to user interactions. Keep it below 100 milliseconds.</p><h3>3. Cumulative Layout Shift (CLS)</h3><p>CLS measures visual stability. Maintain a CLS score below 0.1 to avoid unexpected layout changes.</p><h2>Optimization Techniques</h2><p>Implement lazy loading, code splitting, image optimization, and caching strategies to improve these metrics significantly.</p>

<h2>What Are React Hooks?</h2><p>React Hooks are functions that let you use state and other React features in functional components. Before Hooks, you had to use class components to access state management.</p><h2>The useState Hook</h2><p>The useState Hook lets you add state to functional components. Here's a basic example:</p><pre><code>const [count, setCount] = useState(0);</code></pre><h2>The useEffect Hook</h2><p>The useEffect Hook lets you perform side effects in functional components. It runs after the component renders:</p><pre><code>useEffect(() => { /* effect logic */ }, [dependencies]);</code></pre><h2>Best Practices</h2><p>Always list all dependencies in the dependency array, keep effects focused on a single concern, and use cleanup functions to prevent memory leaks.</p>

<h2>Flexbox: One-Dimensional Layout</h2><p>Flexbox is designed for distributing items in one dimension (rows or columns). It's perfect for navigation bars, button groups, and linear layouts.</p><h2>CSS Grid: Two-Dimensional Layout</h2><p>CSS Grid handles two-dimensional layouts, making it ideal for page layouts with multiple rows and columns. Use Grid for overall page structure.</p><h2>When to Use Flexbox</h2><ul><li>Navigation menus</li><li>Centering content</li><li>Creating responsive rows</li><li>Aligning items in a single direction</li></ul><h2>When to Use Grid</h2><ul><li>Page layouts</li><li>Complex card layouts</li><li>Multi-column designs</li><li>Two-dimensional control needed</li></ul><h2>Combining Both</h2><p>Use Grid for the overall page layout and Flexbox for components within Grid cells. This combination gives you flexibility and powerful layout control.</p>
