1. I have a few edit boxes. The edit boxes should be written right to left. (As each character is typed the text in box grows leftwards).  

2. I should be able to set the font size. Change the edit box borders

3. Set the cursor position anywhere in the editbox

4. When the edit text is changed I need a notification.  

5. The alignment of these edit boxes are precise and they are positioned precisely. These alignments, sizes etc should be preserved to a reasonably degree in all browsers. 

6. This should work in most browsers. It is ok if doesn't work in old browsers. It is ok if they don't work on mobiles.
