Responsive Design and Media Queries
Responsive Design Basics
Responsive Web Design Introduction
Responsive web design ensures that websites look good on all devices such as mobile, tablet, and desktop. It uses flexible layouts, media queries, and modern CSS techniques to adapt content based on screen size. Responsive design is important for SEO because search engines like Google prioritize mobile-friendly websites in rankings.
Core Concepts of Responsive Design
Responsive design works using fluid layouts, flexible images, and CSS media queries. Fluid layouts use percentages instead of fixed units like pixels.
width: 100%;
}
Flexible images scale according to the screen size.
max-width: 100%;
height: auto;
}
Media Queries in CSS
Media queries allow you to apply different styles based on screen width.
body {
background-color: lightgray;
}
}
Common Screen Breakpoints
- Mobile: 0px to 768px
- Tablet: 768px to 1024px
- Desktop: 1024px and above
Mobile First Design Approach
Mobile-first design is a best practice where you design for mobile devices first and then scale up for larger screens.
font-size: 14px;
}
@media (min-width: 768px) {
body {
font-size: 16px;
}
}
Viewport Meta Tag
Viewport meta tag is required for responsive design to work correctly on mobile devices.
Practical Responsive Layout Example

<head>
<meta name=“viewport” content=“width=device-width, initial-scale=1.0”>

display: flex;
flex-wrap: wrap;
}
.box {
flex: 1 1 100%;
padding: 20px;
background: lightblue;
margin: 5px;
}
@media (min-width: 768px) {
.box {
flex: 1 1 45%;
}
}
@media (min-width: 1024px) {
.box {
flex: 1 1 30%;
}
}
</style>
</head>
<body>
<div class=“container”>
<div class=“box”>Box 1</div>
<div class=“box”>Box 2</div>
<div class=“box”>Box 3</div>
