I’m not seeing the new CSS in your child theme – did you remove it? If so, could you please try adding it back so I can take a look directly?
This is what I see now:
@import "../singl/style.css";
.page-header, .page-content, .hentry {
background: none repeat scroll 0 0 transparent;
box-sizing: border-box;
margin: 0 auto 40px;
max-width: 720px;
padding: 40px 40px 20px;
position: relative;
}
.page-id-14 .entry-title {
display: none;
}
.page-id-12 .entry-title {
display: none;
}
.page-id-23 .entry-title {
display: none;
}
table.cnss-social-icon {
margin: 0 auto !important;
}
.entry-thumbnail {
background: none repeat scroll 0 0 transparent;
margin: -40px 0 40px -40px;
width: 720px;
}
