Load Time Impact

The Viewport Meta Tag

The viewport meta tag is essential for responsive design. It tells browsers how to control the page's dimensions and scaling on different devices.

Without this tag, mobile browsers render pages at desktop widths, then scale down—resulting in tiny, unreadable text.

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

<!-- Full recommended settings -->
<meta 
  name="viewport"
  content="width=device-width, 
           initial-scale=1.0,
           maximum-scale=5.0,
           user-scalable=yes"
/>

CSS Media Queries

Mobile-First Approach

/* Base styles for mobile */
.container {
  padding: 16px;
  width: 100%;
}

/* Tablet and up */
@media (min-width: 768px) {
  .container {
    padding: 32px;
    max-width: 720px;
  }
}

/* Desktop */
@media (min-width: 1024px) {
  .container {
    max-width: 1200px;
  }
}

Responsive Grid Example

/* Mobile: Single column */
.grid {
  display: grid;
  gap: 20px;
  grid-template-columns: 1fr;
}

/* Tablet: Two columns */
@media (min-width: 768px) {
  .grid {
    grid-template-columns: 
      repeat(2, 1fr);
  }
}

/* Desktop: Four columns */
@media (min-width: 1024px) {
  .grid {
    grid-template-columns: 
      repeat(4, 1fr);
  }
}
