Hi rebelsnotes,
Please remove the code you have added for rounder corner and copy the below Custom CSS code and paste it to ‘Additional CSS’ field.
.post-block,
.post-boxed,
.post-boxed.inlined .post-img-wrap,
.post,
.hentry,
.type-attachment,
.navigation.post-navigation .nav-links,
.comments-area,
.site-content .widget,
.site-footer .widget {
border-radius: 8px;
-webkit-border-radius: 8px;
-moz-border-radius: 8px;
overflow: hidden;
}
If you want to increase the rounded corner then you can simply do by replacing the digit ‘8’ with your desired one.
Thanks
