hi everyone.. working on a fundraising site for covid-19 relief.. trying to embed a contribution form via code block but the height is limited, forcing one to scroll to see full form... I also tried putting the code into a squarespace embed block. I tried putting entire embed code i was give, including script, into a squarespace code block. I tried putting entire embed code i was given, including script, into a squarespace embed block. I tried injecting script into site-wide head as well as page specific head. I identified block ID and tried CSS injection to change height of block. Nothing works. Anyway you can help? Thanks in advance!
