Fonts that are safe to use within Web sites being displayed in multiple Web browsers and operating systems.
When viewing your website in a variety of Web browsers, you notice that the site's fonts display differently depending on the browser and/or operating system you are using.
Every browser supports many of the same fonts, but not necessarily all fonts. If you want your site to be consistent across multiple browsers we suggest that you use browser safe fonts when creating your site's content. See the related link below.
