• Element: The basic building blocks of HTML, represented by tags like
<div>, <p>, <img>.• Attribute: Additional information attached to HTML elements, such as

Git for tracking changes in code.• Browser DevTools: Tools for debugging and inspecting web pages.
▎⚡️ Performance & Optimization Techniques
• Lazy Loading: Loading resources only when they are needed.
• Minification: Reducing file sizes by removing unnecessary code.
• Code Splitting: Dividing large code into smaller chunks for faster loading times.
• Caching: Storing resources locally to enhance performance.
▎🌐 Web Development Concepts
