Real Components
Real-world components combine multiple CSS properties into complex, interdependent visual systems. A change in one property can cascade through the entire component. Delta-QA tests complete UI patterns to catch regressions that isolated property checks would miss.

Real-world scenarios
🎯
The dropdown that opens behind the table
A developer adds overflow: hidden on a table to fix a horizontal scroll bug. Consequence: the action dropdown on each row opens but stays clipped — only the top half is visible, the "Delete" and "Archive" options are cut off. The developer fixed their scroll bug but didn't check that the dropdowns still worked visually. Delta-QA compares screenshots with the menu open and detects the clipped dropdown — the missing half stands out in the diff.
⚠️
The modal that won't center
A developer changes the body positioning for a new sticky component. Side effect: the confirmation modal shifts to the top-left corner instead of being centered. On mobile, it's partially off-screen — your visitors can't see the "Confirm" button. The release was rushed, they tested the sticky component but not the 5 modals on the site. Delta-QA compares screenshots and highlights the modal's displacement — its new off-center position stands out clearly in the overlay.
💡
The carousel that shows two slides
A CSS change modifies the parent container width of the product carousel. Instead of showing one slide at a time, two slides are now partially visible — the second one is cut in half. It looks visually broken, your customers see a sloppy presentation. The developer changed the container for another reason and didn't even know the carousel depended on it. Delta-QA compares screenshots and detects the second slide appearing partially — the clipped content stands out in the diff.
