Embedded booking widget - change CSS background-color


I have a booking widget for my clients restaurant.

Is it possible to change the background color?

I assume I can apply some custom CSS but not sure where to find the CSS class.

Thanks in advance,


Here is my site Read-Only: [LINK](Webflow - Paper Tiger)

[Published Page - LINK]

Which exact background do you want to change?
Is it something inside here?

This is in iFrame, afaik it is not possible to change that inside Webflow with custom code, at least not with pure css. This is not a problem with Webflow, it is technically not possible to change CSS within an iframe.
I see that you are using a tool called “Now Book it”. I had a quick look at their website, but I can’t find any documentation. Maybe it is possible to add custom CSS to this tool. If it allows to insert custom code, this selector should do the trick:

#root {
background: blue;

Hi Mirko!

Thank you very much for the reply.

I suspected that I would not be able to change the CSS within the iframe.

I just wanted to double check. Thank you for confirming my suspicion.

I believe that it is possible to change the CSS on the tools website. I have asked my client to do so.

Thanks again for taking the time to reply to my post!

All the best,
