Frequently Asked Questions About Responsive Design
What is responsive web design?
Responsive web design creates websites that automatically adapt to any screen size, desktop, tablet, or mobile. Instead of building separate mobile and desktop sites, one site adjusts its layout based on the device viewing it.
Why is responsive design important for my business?
Over 60% of web traffic comes from mobile devices. If your site doesn't work well on phones, you're losing customers. Google also prioritizes mobile-friendly sites in search rankings (mobile-first indexing).
How can I tell if my website is responsive?
Resize your browser window and see if the layout adjusts smoothly. Or use Google's Mobile-Friendly Test tool. Better yet, actually visit your site on different devices and try to complete common tasks.
Is responsive design the same as mobile-friendly?
They're related but not identical. Mobile-friendly means the site works on mobile. Responsive design is a specific approach that creates one site adapting to all devices, the best way to achieve mobile-friendliness.
Does responsive design affect website speed?
Properly implemented responsive design shouldn't hurt speed. However, poor implementation (loading desktop images on mobile, for example) can slow things down. Good responsive design includes responsive images and performance optimization.
