Hello again Ernest,
Thanks ever so much again for your feedback, it’s really helpful.
I didn’t code the front-end of this site, but I have relayed your feedback for future, just around moving the structures via js not being advisable for elements such as this.
For now, I have however added a wrapping structure as you suggested, and moved that instead, and that is now working nicely so at least that is resolved.
Many thanks again and have a lovely weekend :),
Tonya
