I have tried many times with left no stone unturned, but all efforts came in vain. I might be of less knowledge in this area. Then through surfing I found this site as a newbie. I will be very obliged if I get a solution to the below mentioned scenarios.
In GeoServer when I click on "layer preview" button then "Open Layer" for preview, rendered map aligns to the left. I need to align center and give some CSS style and others to the rendered page as below.
- Left side panel for navigational purpose through layers made from PostGIS data.
- Middle side is intended map.
- Right side is for showing some attribute table for the left panel chosen layer

How can I do these?
