1. For the alignment of the titles, yes, it’s possible to align them center. First of, you have custom code that’s affecting the alignment of the titles. This one:
.blog article .entry-header {
display: flex;
flex-direction: row-reverse;
justify-content: flex-end;
}
There’s another one as well, however, I’m not sure if this was added for the alignment of another element. To address this safely, try adding this CSS:
.blog article header.entry-header {
justify-content: center;
}
For the fine line, try adding this CSS as well:
.blog article .entry-title {
border-bottom: solid 1px #00000033;
padding-bottom: 10px;
}
Lastly, to make the categories sticky on desktop, add this as well:
@media (min-width: 1025px) {
.cu-cat-list-div {
position:sticky;
top: 90px;
}
}
