Embed widget and responsive site


I plan to use the embed widget in my site in order to use graphic elements I can easily do with Webflow CMS.

My question is how can I make sure the site will be mobile ready? do I need to make sure the code I add to the widget supports that?

Also, in that case, is is recommended I will use the embed widget for all of the page or can I use it side by side with other webflow objects on the same page?
