Styling a element from a different stylesheet

[fatcatgraphics]

On this site: https://palmshotelfireisland.com You can see they have a booking area, where you can put in your dates. This is from an outside source. Is it possible to style it?

Also in the sidebar here: https://palmshotelfireisland.com/the-palms-hotel/ it has the same thing. How can I make the background of this booking thing a different color?

I tried .aside.x-sidebar.left {background:#000;} but that didn’t work.

Thanks for any help,
Rena

Hello Rena,

I have checked and the forms is loads though an iFrame. Unfortunately, we wont be able to apple CSS to it.

Try checking the settings in the third party source that generated the form if you can get it styled from there.

Thank you.
