paypal standard checkout - position card entry

Question

I'm implementing Paypal Standard checkout. When selecting to pay by card, the card entry fields appear below the button. I'd like to put it into a modal dialog. I can't see any thing in the documentation that does this, but I'm also wondering if this is a limitation to this version. I've looked briefly at Advanced, but it only seem to let you style the box, not define it's position (or put in a modal).

Has anyone done this or something similar that would allow this? Can someone point me in the right direction? The drop down card fields looks pretty nasty on my page (under the basket) once they pop up - looks like an afterthought.

                                        onInit: function (data, actions) {

                                            // Disable the buttons
                                            actions.disable();

                                            $('[id$=chkTerms]').on('change', function (event) {

                                                // Enable or disable the button when it is checked or unchecked
                                                if (event.target.checked) {

When the debit card entry opens, it opens the entry field below the buttons - I'd like to be able to position them into a modal dialog so it looks nicer. It might not even be possible, hence why I didn't provide code originally.
