Special Characters

HTML allows one to specify the properties of a character or set of characters. Thus, if a sequence of characters are to be bold, they are prefixed by the command: and the command is cancelled using . Similarly the start of italics is and at the end is used. The available properties are:

b	bold
i	italic
u	underline
sup	superscript
sub	subscript
pre	fixed font

The TAL question editor has an attributes window which helps you to insert the above properties when using the question editor, in the pre is called Tele Type.

A Newline is inserted using:

Two newlines are inserted by paragraph at the start and at the end.

Colours of fonts: is green

In your questions you may wish to use special ASCII symbols. This is done by specifying that the font face is "symbol" and then specifying the ascii code which is a number given in the table below. Thus the Greek symbol Pi is inserted using:

p which renders the character with ascii code 112 in the symbol font which happens to be a Pi.
