How this plugin works: [Check Docs](https://wpfrank.com/how-to-use-frank-responsive-checker/) You can preview your pages on over fifty devices directly from your WordPress dashboard. ### Viewport and Device Preview Simulation This plugin shows how your pages look on popular mobile screens, tablets, and desktops. * Use the device preview to see mobile views instantly. * Test both portrait and landscape views with one click. * Enter custom width and height values to test any viewport size. * Save your custom device profiles for quick access later. ### Accessibility Testing for Better Usability Check your website pages for common accessibility issues. This helps make your site user-friendly. * Run a WCAG contrast check to read text clearly. * Find images that are missing alt text tags. * Show the keyboard focus order with numbered badges on screen. * Simulate a screen reader to hear how the page is read. ### Screen Capture and Visual Differences Take snapshots of your pages to keep track of layout changes. * Save screenshots of any viewport layout with one click. * Compare two or three device viewports side by side. * Scroll all viewports at the same time to check layout alignment. * Compare new pages against baseline snapshots to find pixel differences. ## Installation 1.
