What HTML codes can I use in my system?

That depends on how a system is delivered to end-users. The Corvid Applet Runtime designs screens using Corvid screen commands. These allow the control of color, font and placement of text and images. In addition, basic <A>, <IMG> and <BR> tags are recognized by the applet. The applet itself is part of an overall HTML page that can contain any HTML commands outside of the APPLET section.

If you are using the Corvid Servlet Runtime user interface screens are designed using HTML templates, which can use the full range of HTML commands. JavaScript, CSS, XML and other extensions to HTML can also be used.
