}Testing tips for Desktop
Viewports this wide are where layouts most often break: check that nothing scrolls sideways, buttons are at least 44px tall, and body text is 16px or larger.
Compare it against a tablet and a desktop width in the same view to catch breakpoint jumps — Responsivly's multi-view does this in one click.
