[BUG] CSS in Template

DESCRIPTION:
There is an extra backslash (\) on line 700 in:
/src/libsodium/src/PremiumTemplates/OptinForms/Lightbox/Gridgum.php

        html div#$optin_uuid div#$optin_css_id.gridgum_container .gridgum_body-form .checkbox-field label input, 
        html div#$optin_uuid div#$optin_css_id.gridgum_container .gridgum_body-form .radio-field label input {
            margin-right: 6px;
\        }

HOW IT EFFECTS THE WEBSITE:
Whenever the template is minified, the spaces are condensed, causing the backslash to escape the closing bracket (\}), which in return causes the template to render incorrectly.

SOLUTION:
Remove the backslash
