Lesson Overview

Simple Explanation

Positioning se element ki exact placement control hoti hai: static, relative, absolute, fixed aur sticky. z-index overlapping order decide karta hai.

Code Explanation

Relative parent ke andar absolute child position hota hai aur sticky header scroll par top pe stick hota hai.

Output Description

Badge corner par dikhega aur header scroll ke dauran top pe rahega.

Practice Exercise

Ek sticky navbar aur image card par top-right absolute badge implement karo.

Extra Explanation

Why This Matters

CSS Positioning and z-index helps you build visual consistency. Reusable classes and a predictable spacing system make interfaces faster and cleaner to build.

Real-World Workflow

Teams usually begin with design tokens for colors, spacing, and type scale. This keeps new components consistent and avoids random values.

Common Mistakes to Avoid

Over-specific selectors, excessive !important use, and mixed units create avoidable bugs. Mobile-first CSS keeps responsive behavior more stable.

Example + Live Practice

.wrapper {
  position: relative;
}

.badge {
  position: absolute;
  top: 8px;
  right: 8px;
  z-index: 2;
}

.header {
  position: sticky;
  top: 0;
  z-index: 10;
}
