Answer 1

This is what I tried and it works perfectly. You do an external CSS or internal CSS. Your choice. If you want internal. Just do a <style> insert the CSS here </style
CSS:
body:not(.modal-open){
padding-right: 0px !important;
}
Internal CSS:
<style>
body:not(.modal-open){
padding-right: 0px !important;
}
</style>
