You can add it in css/override.css with !important tag so it doesn't get overwritten with inline.css. Inline css is calculated & outputted usually from javascripts.
Is there particular module you want to apply this or you want this in general. If general use below css and enable css override from template settings > advanced settings > css override "on".
- Code: Select all
.gkTabContainer2 { height: 300px!important; }
See you around...
