How can I adjust style scripts to modify unwanted space in code?

So I got this weird space between the variant picks but I cant seem to find where it is in the code to remove it.

here it is, on the left there is free space I dont want, so I go to the inspection to see where is it in the code to try to change it but I dont know how to find it on shopify since it says (center right) that its “” class or something. cant seem to find such file ofc on the css of shopify
lets say I want to remove that extra space, how do I remove it based on codes?
where do I find this space in the script so I can make it smaller or delete it completely

thanks

okay edit, found the solution it was an app I deleted that changed it.
anyways, I still want to know how to edit style codes, how do I do that

@Spiegel i think it’s coming from any app. you should target the specific class on which you want to modified the structure.
