Visual QA Toolkit Overview
Front-end polish requires precision alignment and inclusive accessibility verification. UIDesigner Review includes integrated layout overlays and visual impairment simulators directly inside the canvas.
Column & Baseline Grid Overlays
Align typography, card grids, and containers directly against your design system specs without guessing:
- Open the QA Tools dropdown in the canvas toolbar.
- Select Grid Overlay:
- 12-Column Grid: Standard responsive grid with 16px/24px gutters.
- 16-Column Grid: Detailed desktop layout grid for high-density dashboards.
- 8pt Baseline Grid: Horizontal baseline guides for vertical rhythm and line-height inspection.
- Configure column opacity and gutter dimensions in the flyout menu.
- Toggle grids on or off instantly with the hotkey
Shift + G.
Vision Impairment Simulator
Evaluate how users with diverse visual abilities perceive your application in real time:
- Open QA Tools → Vision Simulator.
- Choose a simulation mode:
- Protanopia: Red-blindness (difficulty distinguishing red from green).
- Deuteranopia: Green-blindness (most common form of red-green color confusion).
- Tritanopia: Blue-yellow color blindness.
- Achromatopsia: Complete color blindness (monochrome grayscale view).
- Low Vision / Blur: Simulates cataracts and general visual acuity loss.
- High Contrast: Evaluates system high-contrast display modes.
The canvas applies SVG color matrix filters in real-time, allowing you to browse, click, and interact while verifying that button states, alerts, and charts remain clear and distinguishable.
