There are a few different ways to find fonts that are used on a website. You can use an online tool like Fontanello, Typewolf Type Sample, or Fonts Ninja as described above. These tools will show you the font, style, size, and even give you a link to purchase typefaces used on any website. You can also use your browser's developer tools. In Google Chrome, for example, you can right-click on any element on a web page and select "Inspect." This will open the developer tools, where you can view the source code for that element. This code will list the fonts used on that website, replacing the need for a font detector.
