How to Optimize Layouts for Different Screen Sizes and Orientations on Webflow?

Optimizing layouts for different screen sizes and orientations is essential for delivering a seamless user experience across various devices, whether users are on a smartphone, tablet, or desktop. Ensuring your layout adapts to both portrait and landscape orientations improves usability and accessibility.

How to do it on Webflow?

Use responsive design techniques like CSS media queries to adjust layouts based on screen width, height, and orientation. Ensure that elements like grids, images, and text are resized or repositioned appropriately to maintain a user-friendly interface.

Webflow takes the same approach to media queries as all website builders, using the Desktop breakpoint as a base.

For all the breakpoints below, you will have to adapt the design of your page to make it responsive to all the chosen breakpoints.

Breakpoints and responsive design are a bit off-topic for the checklist. However, if you need to learn more, here is the excellent course from Webflow on breakpoints.
