I have been trying to solve this small issue of changing the modal for the Preloader popup to be bigger so the whole number of A301 can be seen, however I don't understand how Framework 7 design works cus I've been changing many times and it doesn't work.
openCustomPreloader: function () {
var app = this.$app;
app.dialog.preloader('Your Room Number is <p style="font-size:200px;line-height:0px;">A301</p>Checking In');
setTimeout(function () {
app.dialog.close();
}, 6000);
},
