Fonts that come with your computer or device can be called web safe fonts because they're compatible across all different types of devices - laptops, desktop computers as well as mobile phones and tablets!

The standard for web design is a font family that works as well on Windows as it does on Macs and Linux computers, which narrows down our list of choices considerably.
In order to use different font families in your website without worrying about compatibility issues with browsers or other problems, you need access to either an extensive library of specialized typefaces or a tool like Google Font API that allows easy integration into websites. Most commonly used sites allow specific HTML tags such as <h1> through <h6>,<i><u><strong></strong></u><em>(and this last one isn't even technically allowed by all standards)</em>. There are many different fonts that you can use for your website, but there is only a handful of them that will display on all browsers. These web-safe fonts include Arial (A), Verdana (V), Trebuchet MS (Tm) and Georgia typefaces.
There are many types of font styles to choose from when constructing a webpage; however, most users won't be able to see these unless they have the correct browser plug ins installed or certain operating systems such as Windows XP with Service Pack 2 and Mac OS X v10.3 running Internet Explorer 5+, Safari 1+ or Firefox 0+. The four main safe font families includes: Arial - which stands out against its counterpart Tahoma because it's slightly.
