Viewport
What is Viewport?
The Viewport is the physical window through which the user views the website. It is the core concept that drives Responsive Design.
Why Viewports Matter in Responsive Design
Designing for different Viewports is the technical practice of Mobile Responsiveness, which is vital for SEO and UX.
- Responsiveness: Developers use the viewport size to trigger CSS media queries, changing the Layout Grid and element styles accordingly.
- Engagement: Key content (e.g., the primary CTA) must be visible in the initial viewport to maximize Conversion Rate.
- Performance: Ensuring only the content visible in the initial viewport is loaded first is key to improving Page Speed.
Example from Flowtrix Projects
"Flowtrix treats the mobile Viewport as the primary canvas in our Mobile Responsiveness strategy. We design the Hero Section to ensure the key headline and CTA are always immediately visible within the initial viewport, regardless of screen size, guaranteeing maximum impact and high Conversion Rate for the B2B audience.
