I have just finished my own website on beans 🙂 http://alexandraspalato.com/. Just have details to polish.
I have noticed a bug on safari, the modals used for the menu and portfolio look weird 50% of the time. If you see any other but (on windows IE for ex 🙁 ) please report it.
Soon the blog will the filled with beans tutorials 🙂
This looks like it is due to the CSS transitions set on
.uk-modal-dialog in UIkit core. As for the other UIkit stuff, it is better to address your questions straight on their community as there is not much we can do.
