Footer Widget Stays at the Top

Hi, this is my website: Novaxel and everything is but when you click on any button that redirect to a TYPEFORM, the Footer Widget Stays at the Top, like in here: Novaxel Form

How can I solve this? It happens on the desktop and mobile version of my website.

And i have the same problem with this TYPEFORM too: Diseñar mi vestido - Sastrada


I think its because the content of the page only contain an iframe from the Typeform.
To fix this, please set the min-height for your pages using CSS code below:

.site-main {
    min-height: 500px;

Put the code into: Customize > additional CSS.
