Configure with Facebook to Add E-commerce Solutions to FB
I would like to offer my clients Facebook stores so that they can have another way of reaching their customers. Consider allowing users to make designs "Facebook friendly".

In order to design a Facebook page, you just need to make sure you set your site width a little bit smaller.
To do that, go to the “Site Presets” on Webydo’s studio and set your site width narrower than 810 pixels.
This is how Facebook explain it:
“The amount of space available to your tab app is bounded by the outer context of Facebook. It may be configured to display with a width of 520 pixels (default) or 810 pixels.”
