_enrollAccountDialog not styled?

[isocra]

Hi,

I'm using this package and it's great for logging in and change password via the drop down in the nav bar (I'm using this with bootstrap but not bootstrap-3).

However, when I click on a link to enrol, I get a dialog that's almost hidden up in the top left corner of the page.

Investigating, I can find the template _enrollAccountDialog in login_buttons_dialogs.html and it uses classes such as accounts-dialog, accounts-centered-dialog, login-button and login-button-form-submit

But I can't find any styling for them--which explains why they don't display properly.

The thing is, where should the styling be coming from? I've searched on Google and can't find anywhere where anyone has defined these styles, but there surely must be something?

Sorry if I've missed something obvious.
Thanks
