Building a Responsive Mobile Travel Homepage with CSS Flexbox

Project Setup

Project Structure

We’ll use a minimal structrue with root HTML, a css folder for styles, and an images folder for assets like sprite sheets and banner images.

index.html

<!DOCTYPE html>
<html lang="en">
<head>
  <meta charset="UTF-8">
  <meta http-equiv="X-UA-Compatible" content="IE=edge">
  <meta name="viewport" content="width=device-width, initial-scale=1.0">
  <link rel="stylesheet" href="./css/normalize.css">
  <link rel="stylesheet" href="./css/index.css">
  <title>Travel App - Explore Anywhere</title>
</head>
<body>
  <header class="header-bar">
    <div class="search-field">Search: Destinations, Hotels, Attractions...</div>
    <a href="#" class="profile-link">Profile</a>
  </header>
  <section class="hero-banner">
    <img src="./upload/hero-banner.jpg" alt="Featured Travel Destination">
  </section>
</body>
</html>

Base CSS (index.css)

body {
  max-width: 540px;
  min-width: 320px;
  margin: 0 auto;
  font: normal 14px/1.5 "Segoe UI", Roboto, Helvetica, Arial, sans-serif;
  color: #333;
  background-color: #f5f5f5;
  overflow-x: hidden;
  -webkit-tap-highlight-color: transparent;
  box-sizing: border-box;
}

* {
  box-sizing: inherit;
}

Fixed Header with Flexbox

Create a responsive, fixed header that remains centerde across all device widths. Use flexbox to allocate space between the search field and profile link.

.header-bar {
  display: flex;
  position: fixed;
  top: 0;
  left: 50%;
  transform: translateX(-50%);
  width: 100%;
  min-width: 320px;
  max-width: 540px;
  height: 44px;
  background-color: #f8f8f8;
  border-top: 1px solid #e0e0e0;
  border-bottom: 1px solid #e0e0e0;
  z-index: 100;
}

.search-field {
  flex: 1;
  position: relative;
  height: 28px;
  line-height: 26px;
  border: 1px solid #ddd;
  font-size: 12px;
  color: #666;
  margin: 8px 12px;
  padding-left: 28px;
  border-radius: 6px;
  box-shadow: 0 1px 3px rgba(0, 0, 0, 0.1);
  background-color: #fff;
}

.profile-link {
  width: 44px;
  height: 44px;
  font-size: 12px;
  text-align: center;
  color: #2da4e0;
  text-decoration: none;
}

Profile Link Styling

Add an icon using a 2x resolution sprite sheet for sharp display on high-DPI screens. Position the icon above the profile text.

.profile-link::before {
  content: "";
  display: block;
  width: 22px;
  height: 22px;
  background: url(../images/icons-sprite.png) no-repeat -60px -195px;
  background-size: 104px auto;
  margin: 4px auto 2px;
}

Search Field Icon

Insert a magnifying glass icon inside the search field using absolute positioning and the same sprite sheet.

.search-field::before {
  content: "";
  position: absolute;
  top: 4px;
  left: 6px;
  width: 16px;
  height: 16px;
  background: url(../images/icons-sprite.png) no-repeat -60px -280px;
  background-size: 104px auto;
}

Hero Banner

Adjust padding to account for the fixed header, ensuring the banner is visible below it.

.hero-banner {
  padding-top: 44px;
}

.hero-banner img {
  width: 100%;
  height: auto;
  display: block;
}
