TYPE = VERTICAL

VERTICAL inserts vertical space between lines of text. VERTICAL makes the space look like a really big paragraph break. (However, don't use VERTICAL when you mean <P ...>. If you really intend a paragraph break, use VERTICAL and <P ...> together). When you use VERTICAL, you must also use the SIZE attribute, not HEIGHT.

this code produces this
hi there!

<SPACER TYPE=VERTICAL SIZE=50>

hi there!

<SPACER TYPE=VERTICAL SIZE=200>

hi there!
hi there! hi there! hi there!
