Answer 1

You need to set the right property to 100%, so it will be pushed just outside the left boundary:

right: 100%;

Answer 2

you can make

right: 100%;

and you can use table if you new in css

<table align="center" width="100%" cellpadding="0" cellspacing="0" border="0">
<tr>
<td valign="top" width="50%" align="right">left</td>
<td valign="top" width="50%">right</td>
</tr>
</table>
