Hey Leanne,
the CSS rules you’re after are as follows:
– to remove the “comments closed” text:
.nocomments { display: none; }
– to add extra padding around images in posts and projects:
.post-content img { padding: 10px; }
(you can of course change the “10” to any number you need ;)
You can add the CSS to the “Style: Add Custom CSS” tab of the Theme Options panel.
Sincerely,
Andrii / Satori Studio
