Change TLN From Horizonal appreance to Vertical

Dear SDN,

               I am designing the basic framework of a portal page for anonomous user for a prototype. My need is to change the TLN From Horizontal TLN TO a Vertical TLN to the left. I know that the par file needs to be edited for the TLN change.

So my questions are :-

1. If i make changes in the html part for TR And TD part of the code, will it work ?

2. I want to make this changes effective for an ananomous user , so i thought i would write A par, assign a page to this.Add mapping rules and assign a desktop to this.

Am i moving in corect direction, is there any documentation for the same.?

Regards,

Anirban Ghatak.
