Minor changes on staging site - Before update

Good Day.

We run a online auction site using wordpress + woocommerce + simple auctions + wcfm

All my pages are build on Elementor

We have a staging site and need some minor changes on a few pages.

5 x archive pages already build - we need custom sorting by code
2 x archive pages some minor changes with css
Play videos on home page first time (chrome)
Add CSS to WCFM page to allow vendors to see inventory tab
Block bids from users if own product

Regards
