CSS Responsive Web Design - Introduction

When you use CSS and HTML to resize, hide, stack, shrink, or move the content to make it look good on smaller screens, it is a responsive design.

Example:

To create the example above follow the steps below:

Step1.

Add HTML

Include the following <meta> viewport element in your website code:

<!DOCTYPE html>
<html>
<head>
<meta name="viewport" content="width=device-width, initial-scale=1.0">
</head>
<body>

<div class="header">
  <h1>Fashion Store</h1>
</div>

<div class="row">
  <div class="col-3 col-s-3 menu">
    <ul>
      <li>Jackets</li>
      <li>Shoes</li>
      <li>Bags</li>
      <li>Dresses</li>
    </ul>
  </div>

  <div class="col-6 col-s-9">
    <h1>New In</h1>
    <p>Discover all the new arrivals of the women's ready-to-wear collection Fall-Winter 2021. Browse items that you need for your store: dresses, shoes, bags...</p>
  </div>

  <div class="col-3 col-s-12">
    <div class="aside">
      <h2>About Us</h2>
      <p>Our clothing and accessories are carefully curated to provide our customers the latest fashions.</p>
      <h2>Shipping</h2>
      <p>Worldwide Shipping.</p>
      <h2>Privacy & Cookies</h2>
      <p>When you visit our website, our web server collects some basic information such as your internet service provider's domain name...</p>
    </div>
  </div>
</div>

<div class="footer">
  <p>Resize the browser window to see the resizing effect.</p>
</div>

</body>
</html>

Step2.

Add CSS

Add the CSS @media rule to apply different styles for different media types/devices:

<style>
body {
  margin:0;
  padding:0;
}

* {
  box-sizing: border-box;
}

.row::after {
  content: "";
  clear: both;
  display: table;
}

[class*="col-"] {
  float: left;
  padding: 15px;
}

html {
  font-family: tahoma;
}

.header {
  background-color: #0a9396;
  color: #ffffff;
  padding: 15px;
}

.menu ul {
  list-style-type: none;
  margin: 0;
  padding: 0;
}

.menu li {
  padding: 8px;
  margin-bottom: 7px;
  background-color: #005f73;
  color: #ffffff;
  box-shadow: 0 1px 3px rgba(0,0,0,0.12), 0 1px 2px rgba(0,0,0,0.24);
}

.menu li:hover {
  background-color: #0a9396;
}

.aside {
  background-color: #005f73;
  padding: 15px;
  color: #ffffff;
  text-align: center;
  font-size: 14px;
  box-shadow: 0 1px 3px rgba(0,0,0,0.12), 0 1px 2px rgba(0,0,0,0.24);
}

.footer {
  background-color: #001219;
  color: #ffffff;
  text-align: center;
  font-size: 12px;
  padding: 15px;
}

/* For mobile phones: */
[class*="col-"] {
  width: 100%;
}

@media only screen and (min-width: 600px) {
  /* tablets: */
  .col-s-1 {width: 8.33%;}
  .col-s-2 {width: 16.66%;}
  .col-s-3 {width: 25%;}
  .col-s-4 {width: 33.33%;}
  .col-s-5 {width: 41.66%;}
  .col-s-6 {width: 50%;}
  .col-s-7 {width: 58.33%;}
  .col-s-8 {width: 66.66%;}
  .col-s-9 {width: 75%;}
  .col-s-10 {width: 83.33%;}
  .col-s-11 {width: 91.66%;}
  .col-s-12 {width: 100%;}
}
@media only screen and (min-width: 768px) {
  /* desktop: */
  .col-1 {width: 8.33%;}
  .col-2 {width: 16.66%;}
  .col-3 {width: 25%;}
  .col-4 {width: 33.33%;}
  .col-5 {width: 41.66%;}
  .col-6 {width: 50%;}
  .col-7 {width: 58.33%;}
  .col-8 {width: 66.66%;}
  .col-9 {width: 75%;}
  .col-10 {width: 83.33%;}
  .col-11 {width: 91.66%;}
  .col-12 {width: 100%;}
}
</style>
