Content order
Put the most important information and action early. Multi-column desktop layouts should collapse in a meaningful reading order.
Tap targets
Buttons and menu controls need enough size and spacing to operate accurately on touch screens.
Responsive settings
Visual builders including Divi provide device-specific controls, but use overrides selectively so the design system remains maintainable.
Performance
Compress media, avoid unnecessary scripts and test on realistic network conditions. Builder choice alone does not determine speed.
