About Viewport Dimensions

Viewport Dimensions is a simple Chrome extension for web developers and designers who want to quickly visualize the viewport dimensions when actively resizing the browser window. This extension dynamically displays the current viewport dimensions (width and height in pixels) in real-time as you resize your browser window, making it easier to see how your site adapts to different screen sizes. Key Features: - Real-Time Viewport Display: Instantly see the current viewport dimensions as you resize your browser window. - Customizable Display Options: Choose where the dimensions are displayed (top-right, bottom-right, top-left, bottom-left) and customize the font size, text color, background color, and background opacity to match your preferences. - Toggle Visibility: Easily enable or disable the viewport dimensions display without uninstalling or disabling the extension. - Responsive to DevTools: The extension adjusts the displayed dimensions to account for the presence of Chrome's Developer Tools panel. - Timeout Setting: Set the time period the dimensions are displayed after the change or set it to always be displayed. NOTE: This extension was built to replace the previous "Viewport Dimensions" extension ID: kchdfagjljmhgapoonapmfngpadcjkhk, which is no longer supported by the Chrome Web Store. If you relied on the old extension, this new version offers the same functionality with additional customization options and improved performance.
