Hi so i am trying to learn here - inspected the element and found it was the main product liquid that controlled it so added the code in bold below to that section

**

it was the section yellow - it never worked and wonder why ? this was the url - https://kitout-fitness.co.uk/products/customizable-mockup-ladies-racerback-cropped-tank-top?variant=52036624482633#product-modal what steps would you of taken to solve and identify the relevant section that needed changing thanks shane

TBH i think im going in the wrong place as you can see below 2 elements when space is inbetween elements like this - how do you find out as part of problem solving and solution which one is causing that space thanks
