My name is Octavian from RSJoomla!. I hope you don't consider that I'm hijacking this thread, I want to make some clarifications:
We've bought a subscription from you, as you can see, and yes, we've tested one of your templates (they're really all the same, the sample data is different). Some questions:
Why didn't you implement - like all other frameworks out there - a 12 column grid system? It's been requested on GitHub but seems the ticket has been closed:
We've had to resort to creating our own classes to emulate this; we thank everyone in the issue tracker for their suggestions, they helped us overcome this limitation.
PS: Is the bug where your page builder is triggering content plugins twice fixed? We keep getting tickets from customers, I'm sure you know what I'm referring to.
Since you've already given us access to your website in our support system, I went ahead and logged in to take a look at your form. I've made a duplicate of it here:
And removed all the CSS code and extra classes you've added on the fields - to make sure that there's nothing interfering. Apart from the issue of black inputs on a black background with black text (coming from the template, it seems you were overriding them with grey backgrounds from your own code) and the fact that the Stripe elements aren't styled (that's how they work, you need to rewrite the CSS on the fields for them to look like your other fields), I don't see any other issues.
I've also removed the "uk-form-horizontal" class since you plan on not using labels next to your fields and they were taking up space.
Please update to 2.0.2, as you're missing the custom grid classes I'm talking about. When you disabled the loading of our version of UIkit 3, the classes were not loaded - that's an oversight from our side and has been fixed.
