I’m not a coder but googling, tweaking here and there suddenly I got everything I wanted. Therefore I’ll just share the Additional CSS code I have, so that you can give it a try.
body.page-template-blog-layout:not(.home) header.entry-header {
text-align: left;
}
body.page-template-blog-layout:not(.home) header.entry-header .entry-title{
font-size:1.5em;
margin-bottom:0px;
}
.copyright {
display: none !important;
}
section[class*="-section"] .widget-title:after, .section-title span:after {
background: #ffde23;
}
