Hi @sifu and @colinf,
It seems that the underline on links comes from themes’ CSS. Please use the following codes in order to remove it:
.entry-content a,
.entry-summary a,
.comment-content a,
.widget a,
.site-footer .widget-area a,
.posts-navigation a,
.widget_authors a strong {
box-shadow: none !important;
}
.entry-content a:focus, .entry-content a:hover, .entry-summary a:focus, .entry-summary a:hover, .comment-content a:focus, .comment-content a:hover, .widget a:focus, .widget a:hover, .site-footer .widget-area a:focus, .site-footer .widget-area a:hover, .posts-navigation a:focus, .posts-navigation a:hover, .comment-metadata a:focus, .comment-metadata a:hover, .comment-metadata a.comment-edit-link:focus, .comment-metadata a.comment-edit-link:hover, .comment-reply-link:focus, .comment-reply-link:hover, .widget_authors a:focus strong, .widget_authors a:hover strong, .entry-title a:focus, .entry-title a:hover, .entry-meta a:focus, .entry-meta a:hover, .page-links a:focus .page-number, .page-links a:hover .page-number, .entry-footer a:focus, .entry-footer a:hover, .entry-footer .cat-links a:focus, .entry-footer .cat-links a:hover, .entry-footer .tags-links a:focus, .entry-footer .tags-links a:hover, .post-navigation a:focus, .post-navigation a:hover, .pagination a:not(.prev):not(.next):focus, .pagination a:not(.prev):not(.next):hover, .comments-pagination a:not(.prev):not(.next):focus, .comments-pagination a:not(.prev):not(.next):hover, .logged-in-as a:focus, .logged-in-as a:hover, a:focus .nav-title, a:hover .nav-title, .edit-link a:focus, .edit-link a:hover, .site-info a:focus, .site-info a:hover, .widget .widget-title a:focus, .widget .widget-title a:hover, .widget ul li a:focus, .widget ul li a:hover {
