Responsive Web Design Explained
Responsive web design means your site looks and works on every screen size. Phone, tablet, laptop, and desktop. Here is why that matters for your business and how we build for it.
Definition
What is responsive web design?
Responsive web design is a development approach where layout, images, and navigation adjust automatically to the viewer screen width. One site serves all devices using CSS media queries and flexible grids instead of separate mobile URLs.
Responsive vs adaptive vs separate mobile sites
Responsive design uses one codebase that flexes to any screen width. Adaptive design serves different layouts at specific breakpoints.
Separate mobile sites on m.yoursite.com are outdated and hurt SEO. We build responsive sites with one URL and one codebase for every device.
Why responsive design matters for your business
Over 60% of web traffic comes from mobile devices. Google uses mobile-first indexing, so a site broken on phones loses rankings and leads.
Visitors unable to tap your phone number or read your menu on a small screen call your competitor instead.
How we test responsive design
We test every site at 320px for small phones, 375px for iPhone, 768px for tablets, 1024px for laptops, and 1440px or wider for desktops.
We check touch targets, readable font sizes, image scaling, and form usability at each breakpoint. Google PageSpeed Insights on mobile runs before every launch.
