  This tool is designed for web developers, designers, and enthusiasts who want to know Tailwind CSS usage across various sites.
  
  Features:
  
  ⚡ Automatic Detection: Discover instantly if a website is using Tailwind CSS as soon as you navigate to it. The extension analyses both external stylesheets and inline styles.
  
  ⚡ Version Identification: Not only does the extension detect the presence of Tailwind CSS, but it also determines the specific version used, helping you understand which features and utilities are likely employed.
  
  ⚡ Badge Display: A badge on the extension icon provides quick information about the detected Tailwind CSS version, or it remains blank if Tailwind CSS isn’t found.
  
  ⚡ Efficient Caching: Results are cached per domain to optimize performance and minimize redundant checks, ensuring swift browsing without repetitive processing.
  
  ⚡ Easy Access: Use the popup to get a summary of the detection results and access settings to customize the extension's behavior.
  
  ⚡ Theme Support: Toggle between light and dark themes for the extension’s popup window, aligning with your preferred visual style.

  Built with Tailwind CSS tells you whether the site you’re on uses Tailwind CSS—and when possible, which version—without leaving the page. It’s for developers, designers, and anyone curious how a site is styled.
  
  Open the popup to see a clear yes/no style result, the current site’s hostname, and a refresh if you want to scan again. A small badge on the extension icon can show a short version hint when Tailwind is found (Chrome only fits a few characters there). You can switch light or dark theme for the popup.
  
  Everything runs in your browser: it inspects stylesheets and related page content to detect Tailwind-style signals. Results are cached per domain on your device so repeat visits stay snappy; cache can reset on a long schedule. No accounts, no tracking, and nothing is sent to us—this is an open-source tool you can review on GitHub: https://github.com/dankore/built-with-tailwind-css
  
  If you work with Tailwind or compare sites often, install it to get an instant read on Tailwind usage while you browse.
