In graphics, any font will display exactly as you insert it. For actual text (anything you can highlight with your mouse), you can use any font that’s available on the internet, but if a visitor doesn’t have that font, they will see Times New Roman or their default browser font. The graphic to the right shows some fun fonts that display exactly as they are by using a graphic!
The 12 fonts listed below are installed on both pc and mac and are considered as ‘safe’
arial, arial black, comic sans ms, courier, courier new, georgia,
helvetica, impact, palatino, times new roman, trebuchet ms, verdana.
The wording is actually the font, so you can see what the text on your site would look like if you picked Arial, for example.
