Core Building Blocks

Every web application relies on three foundational technologies: HTML5 for structure, CSS3 for styling, and JavaScript ES6+ for client-side interactivity.

// Example: Lightweight ES6+ DOM Manipulation
document.addEventListener("DOMContentLoaded", () => {
  const calcBtn = document.getElementById("calc-btn");
  calcBtn?.addEventListener("click", () => {
    console.log("Interactive tool initialized!");
  });
});
