/* Tips for sidebar1:
1. Since we are working in relative units, it's best not to use padding on the sidebar. It will be added to the overall width for standards compliant browsers creating an unknown actual width. 
2. Since em units are used for the sidebar value, be aware that its width will vary with different default text sizes.
3. Space between the side of the div and the elements within it can be created by placing a left and right margin on those elements as seen in the ".twoColHybLtHdr #sidebar1 p" rule.
