Browser support

Spectre uses Autoprefixer to make most styles compatible with earlier browsers and Normalize.css for CSS resets. Spectre is designed for modern browsers. For best compatibility, these browsers are recommended:

  • Chrome (LAST 4)
  • Microsoft Edge (LAST 4)
  • Safari (LAST 4)
  • Opera (LAST 4)
  • Internet Explorer 10+

Spectre supports Internet Explorer 10+, but some HTML5 and CSS3 features are not perfectly supported by Internet Explorer.
