Regarding that button styling issue, I already help you applied into this following css file, it should render correctly now.

JoomlaFolder/templates/rt_supra/css/animate.css

#payplans.payplans-wrap #payplans-order-confirm {

	width: inherit !important;

}

Is there a way to limit the width of PP for large and extra large screens. I just looks lost especially since I can't put it into a module position and Gantry 5 doesn't work because you change pages for the invoicing.
I may miss something but it just seems very difficult to make it work for my site. I may have to return the product.

Perhaps you can elaborate more details which kind of large or extra large screens you referring?

The CSS change didn't work and I put it into /home17/soulfoo1/public_html/templates/rt_supra/custom/scss/custom.scss where all custom changes go. Still it didn't work.
I send you another screen shoot. I just need it more compact. And the buttons have to be fixed.

The reason why you put my custom css into this file (public_html/templates/rt_supra/custom/scss/custom.scss) it doesn't work is because you have to recompile your CSS from your template in order to show your latest custom css code on the page.

Currently it always load this compiled css file (https://soulfood.cafe/templates/rt_supra/custom/css-compiled/custom_41.css?59ee7860), that is why i put my custom css into this file JoomlaFolder/templates/rt_supra/css/animate.css

It would be best if you can consult with your current template provider and see how to perform recompile css stylesheet from your template, so that your custom css only can load on your site.

If you would like to fix it immediately, i would suggest you temporary put these following custom css into this file
JoomlaFolder/templates/rt_supra/css/animate.css

#payplans.payplans-wrap #payplans-order-confirm {

	width: inherit !important;

}



#payplans.payplans-wrap input[type="text"]#app_discount_code_id{

    width: 20% !important;

}



#payplans.payplans-wrap .payplans [class="btn"] {

    background-color: #2276e3 !important;

}

I added the membership to my menu - Online Cafe - Membership. For some reason, it is going now in a loop. Further, what is the best way to add the Registration from the membership menu?
