A short article to introduce 3 of my favourite bookmarks. I use them all the time. No need to install addon or extension, just drag and drop them in your bookmarks bar to start using them.
- The first one is Responsive Design Bookmarklet, a handy tool for responsive design testing.
http://responsive.victorcoulon.fr - The second is Fount, identify web fonts on any site. It tells you in a click, the font, font size, weight and style.
http://fount.artequalswork.com - The third one is Wappalyzer, it tells you about what frameworks are used in the page your are visiting.
