Mobile Responsive Test

Layout Breakdowns

• •Horizontal scrolling caused by fixed-width elements wider than the viewport
• •Two-column layouts that don't stack to single column on narrow screens
• •Absolute positioned elements overlapping content unexpectedly
• •Modals and popups that extend beyond screen boundaries

Touch Interaction Problems

• •Buttons under 44px that are difficult to tap accurately
• •Dropdown menus designed for hover that don't open on touch
• •Links placed too close together causing accidental taps
• •Forms with inputs that trigger unwanted zoom on iOS (font-size under 16px)

Typography Issues

• •Text too small to read without zooming
• •Long words or URLs breaking layout on narrow viewports
• •Headings that don't scale down proportionally
• •Insufficient line spacing making text blocks hard to scan

Navigation Failures

• •Desktop hamburger menus that don't open or close correctly
• •Fixed navigation bars consuming too much vertical space
• •Sticky elements that cover page content on scroll
• •Back button behavior breaking due to JavaScript routing

Fix Horizontal Overflow

The most common mobile layout issue is content wider than the viewport. Add this CSS to catch all overflowing elements and identify the culprit:

/* Temporarily add to find overflow source */
* { outline: 1px solid red; }

/* Permanent fix to prevent overflow */
html, body {
  overflow-x: hidden;
  max-width: 100%;
}

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

Fix Input Zoom on iOS

iOS Safari automatically zooms into inputs with font-size under 16px. This disrupts the layout and frustrates users. The fix is simple:

/* Prevent iOS zoom on input focus */
input, select, textarea {
  font-size: 16px; /* Never below 16px */
}

/* Or use rem equivalent */
input {
  font-size: 1rem;
}

Ensure Touch Targets Are Large Enough

Small buttons are the number one cause of mobile usability complaints. Use padding rather than fixed height to create larger tap areas:

/* Minimum touch target sizes */
button, a, [role="button"] {
  min-height: 44px;
  min-width: 44px;
  padding: 12px 16px;
}

/* Increase spacing between adjacent targets */
nav a + a {
  margin-left: 8px;
}

Responsive Typography with clamp()

Instead of different font sizes at each breakpoint, use CSS clamp() for fluid typography that scales smoothly between screen sizes:

/* Fluid typography — no media queries needed */
h1 {
  font-size: clamp(1.75rem, 5vw, 3rem);
}

h2 {
  font-size: clamp(1.25rem, 3.5vw, 2rem);
}

body {
  font-size: clamp(1rem, 2.5vw, 1.125rem);
}
