Typecase makes working with web fonts in WordPress a glorious experience. With over 650 fonts from Google Web Fonts, Typecase is a unique and easy-to-use typography plugin that allows you to quickly browse, find, and select fonts to apply to your website.
Developed by <a href="http://upthemes.com" rel="nofollow ugc">UpThemes</a>.
Typecase works out-of-the-box with all the default themes, including the brand new Twenty Fifteen. We’ve incorporated new controls for font selection with the Customizer, making it easy to select fonts that fit your style.
<h3>Advanced Usage</h3>
Typecase offers the ability to apply fonts to any theme through the use of CSS. If you don’t know how to find CSS selectors to target in your theme, make sure to ask the original theme author to implement theme support for Typecase. Once the theme declares support for Typecase, you will easily be able to customize the fonts in your theme without the need for using CSS selectors.
