Remove stripe

Many thanks.

Hello there,

I hope you are doing well today.

You can use the following CSS code to remove the border by going to Appearance > Customize > Additional CSS and pasting it there.

.section-title:after, .page-title:after, .newspaper-x-content .widget-title:after, .newspaper-x-after-content-sidebar .widget-title:after, #comments > h3:first-of-type:after, #reply-title:after, .newspaper-x-related-posts .newspaper-x-related-posts-title > h3:after {
    border-bottom: none;

Best Regards,
