CSS Superhero Required for TM Extra Product Options Update CSS

Hi There

I am looking for a UK or US based coder to help me fix a couple of CSS issues after an update. This requires somene who is experianced in CSS.

I have updated the website and lost some CSS on;
1. my product variations ( created with TM Extra Product Options)
2. tabs
3. Checkout page - deliver to different address box

I just want the new website to look like the old website in terms of these CSS styles (I have copies of both the updated website and old website to grab and compare code).

Variations - It looks like in the new version of the plugin some div tags have been removed and the width is being calculated with flex (I just had it at images@ 100% display inline block and float left). However I am not sure how to overwrite the new code.
Tabs - page builder and theme update they are just blank now on home page and product pages.

All CSS is in a custom css section within the theme files so I would ideally like the code to be added there with the rest so I can quckly rcopy and paste this onto the live website when I run a live update.

The website is behind a coming soon page but I can give you access to discuss budget further for qualified applicants. If you let me know your rate per hour and how many hours you think it will take that would be the best for us to determine budget.

I have some custom PHP tweak jobs coming up too so if you are a coder as well please mention this. Ideally I would like this to be completed before the end of the week so I can update the live website over the weekend.
