Type Wonder is an online tool allowing you to preview how the different fonts will look like on your website. Now you won't need to go through the code of the site to test a new font, everything is achieved via the interface TypeWonder.
To use this tool, simply go to TypeWonder and enter the URL of the site you want to test.
The next step is to select a font (a list will be automatically generated).
Validate your choice by pressing on the Use button.
You can preview a different font by clicking on the "Change font" button.
To apply the font of your choice, click on the "Get Code" button to get the HTML code.
