Borders

You can try adding a bottom border description to .entry-title

.entry-title {
color: #000;
font-size: 21px;
font-weight: bold;
border-bottom:3px solid #000000;
}

I think that might work.

no- that didn’t work unfortunately.

I’ve changed the style of my posts slightly. My main concern is to create a border between posts.

Where would the code be best positioned for this on the stylesheet?

I want to create borders underneath post titles

My main concern is to create a border between posts.

Two entirely different things. If you look again, there is now a solid black 3px underline at your post titles. That’s what the code I gave you did. the title “First Post” Now has an underline. -although I see you must be working on it, because the titles are now gone. ??

This will put a border/horizontal line at the bottom of each post;

.hentry {
margin: 0 0 48px 0;
position: relative;
border-bottom: #000000 2px solid;
}

Yes sorry I did notice that and my blog is very much a work in progress. I tried what you suggested and it works, which is perfect! Thank you so much for your help! ??

Glad it worked!
