Vertical tabs – changes in css codes

Hi,
Thank you very much for your great plugin. I’m using vertical tabs
shortcodes. I want to change width of tab titles e.g.
<—————- 100 % ——————————->
Tab 1 (40px -> 20px) – aaaaaaaaaaaaaaaaaaaaaaaaaaaaaa
Tab 2 (40px -> 20px) – bbbbbbbbbbbbbbbbbbbbbbbbbbbbbb
Now It is possible to fix a width of table (width = “100%”). Is it possible to determine widths separately one for tab titles and the second one for table?

Have a nice day.
Kind regards,
Robert
