How to fix iframe scrolling issue

Hi all,

I am trying to create a page where I can integrate my ticket provider's widget to sell tickets without navigating to an external website!

The widget is set up, but the issue is that once you click a ticket to buy, the billing information content is longer than the ticket list - therefore the contents of the widget become scrollable.

This results in an awful experience on mobile - but also on laptop - where both the page and widget are scrollable.

The goal is to have a dynamic code block, that doesn't become scrollable. I am open to dropping the header / footer of the page even, just to give a clean experience! 

I cannot really reach out to change anything on the widget I'm afraid.

My unlisted ticket page: https://www.santsat.com/hmmm

The code provided by the ticket site:

<iframe src="https://cooltix.com/widget/event-products/65c7a27183404a4e342011f8" width="100%" height="1000" frameborder="0"></iframe>

I have subscribed to a business plan now so I can use code blocks as I felt the issue may be limitations of the embed block.

Please help me resolve this!

Thank you,
Marci

Use some CSS code like this

#block-yui_3_17_2_1_1708340345163_4777 iframe {
    height: 1500px !important;
}

That doesn't work tuanphan
