- Responsive Design
- Mobile-First Design
What is Responsive Design?
Responsive Design is a web design approach that automatically adjusts a website’s layout and content based on the screen size. The goal is to ensure that users have a seamless experience whether they’re on a desktop, tablet, or smartphone.
How It Works:
- The website is first designed for larger screens (like desktops).
- Using CSS media queries, the layout resizes or rearranges itself based on the screen width.
- The same content is delivered to all devices, just presented differently.
What is Mobile-First Design?
Mobile-First Design flips the process. As the name suggests, the website is first designed for mobile devices, then gradually improved for larger screens like tablets and desktops.
How It Works:
- Designers start with the smallest screen (usually a smartphone).
- Core features are built and optimized for mobile users.
- As the screen size increases, additional features and enhancements are added.
