Venue text in serach result small - how to change

HI
I have recently purchased and just started to use OS Booking. It appears to be excellent, thank you.

I have however not found a way to change the inline CSS.
When displaying venue information the text is font-size:11px; far too small for my site.
I have tried changing the helper/common.php file as an override in my template but it does not seem to work this way.

Can anyone help with how to change this other than changing the core component file?
Same applies to the 'service cost with this employee' statement below it

I have managed how to do this for the 'service cost with this employee' as it had a class attached to it, but the venue and employee descriptions have inline text.

I also see that the service tabs at the top have inline styles so would want to know if this can be changed too.

Can I do this safely in the core component files or will I lose those changes at the next update?

Hi Richard,
OS Services Booking doesn't have overrided layout feature, so after installing new OS Services Booking version, you will need to re-do the modification again.
Thanks
Dam

ok thank you
