Using fonts in traditional HTML-based Web applications is problematic because they are platform dependent: if the font you are using in an HTML page is not available on the end user platform, a substitution font is used with no guarantee of what the end result will look like. Using OpenLaszlo, you can embed fonts in your application using the <font> tag. You use the name attribute to provide the font with a logical name used within your application, and the src attribute to point to a font file. Just like images, font files have to be available on the server. This approach guarantees that your application will look exactly the same, pixel by pixel, on all platforms.
