Mobile layout.
THE STARTING POINT
Most of your visitors are on phones.
Design for that first, not as an afterthought.
WHAT BREAKS ON MOBILE
Multi-column layouts that do not stack sensibly Text that becomes tiny Buttons too small to tap Tables that overflow Images that force horizontal scrolling Fixed elements covering content
WHAT TO CHECK
Every page, on an actual phone.
Not a resized desktop browser.
BUILDER PREVIEW MODES
Useful and not sufficient. They approximate.
THE STACKING QUESTION
When columns stack, what order do they appear in?
Frequently not the order you intended, which puts the important content below the fold.
Check it.
TAP TARGETS
Buttons and links need enough space around them to tap accurately.
TABLES
Rarely work on phones. Consider an alternative presentation.
