What is Responsive Design?

Responsive Design is a web design method that makes a website automatically adjust its layout, images, and text according to the screen size.

• A responsive website “responds” to the user’s device.
• It scales images, text, and layouts without breaking the design.
• The goal is a seamless user experience across all devices.

Why Responsive Design Matters?

Responsive Design isn’t just about looks—it’s about usability, accessibility, and ranking. Let’s break it down:

Mobile-First Approach

• Over 60% of internet traffic comes from mobile devices.
• Google uses mobile-first indexing, meaning it ranks your site based on how it performs on mobile.
• If your website isn’t responsive, it can lose traffic, users, and search ranking.

Device Variety

• Users browse on desktops, laptops, tablets, smartphones, TVs, and even smartwatches.
• Responsive Design ensures your site adapts automatically to all devices.
• This avoids creating separate websites for each screen size, saving time and cost.

Example of Responsive Design (HTML + CSS)

<header>
    <h1></h1>
    <p></p>
  </header>

  <section class="features">
    <div class="box"></div>
    <div class="box"></div>
    <div class="box"></div>
  </section>

body {
  margin: 0;
  font-family: Arial, sans-serif;
}

header {
  background: #0078d7;
  color: white;
  text-align: center;
  padding: 20px;
}

.features {
  display: flex;
  flex-wrap: wrap;
  padding: 20px;
}

.box {
  flex: 1 1 300px;
  margin: 10px;
  padding: 20px;
  background: #f4f4f4;
  border-radius: 8px;
  text-align: center;
  font-size: 20px;
}

/* Tablet screen */
@media (max-width: 1024px) {
  .box {
    flex: 1 1 45%;
  }
}

/* Phone screen */
@media (max-width: 600px) {
  .box {
    flex: 1 1 100%;
    font-size: 18px;
  }
}
