Flexible Images - Media yang scale automatically
CSS Media Queries - Conditional styling based on screen size
Viewport Meta Tags - Proper mobile rendering control

Cara Membuat Website Responsif: Step-by-Step Guide

Step 1: Set Viewport Meta Tag

Viewport meta tag adalah foundation dari responsive design:

<meta name="viewport" content="width=device-width, initial-scale=1.0">

Tag ini instructs browser untuk:

Set page width sama dengan device width
Set initial zoom level ke 100%
Control scaling behavior di mobile devices

Step 2: Implement Fluid Grid System

Fluid grid menggunakan relative units instead of fixed pixels:

.container {
  width: 100%;
  max-width: 1200px;
  margin: 0 auto;
}

.column {
  width: 100%;
  float: left;
}

@media (min-width: 768px) {
  .column {
    width: 50%;
  }
}

@media (min-width: 1024px) {
  .column {
    width: 33.33%;
  }
}

Step 3: Create Responsive Images

Responsive images adapt ke screen sizes untuk optimal loading:

img {
  max-width: 100%;
  height: auto;
}

/* Advanced responsive images */
.responsive-img {
  width: 100%;
  height: auto;
  object-fit: cover;
}

Step 4: Implement CSS Media Queries

Media queries enable conditional styling based pada device characteristics:

/* Mobile First Approach */
/* Base styles for mobile */
.navigation {
  display: block;
  width: 100%;
}

/* Tablet styles */
@media (min-width: 768px) {
  .navigation {
    display: flex;
    justify-content: space-between;
  }
}

/* Desktop styles */
@media (min-width: 1024px) {
  .navigation {
    max-width: 1200px;
    margin: 0 auto;
  }
}

Step 5: Optimize Typography

Responsive typography ensures readability across all devices:

/* Fluid typography */
body {
  font-size: 16px;
  line-height: 1.6;
}

h1 {
  font-size: clamp(1.5rem, 4vw, 3rem);
}

@media (min-width: 768px) {
  body {
    font-size: 18px;
  }
}
