how to get borders around my posts

Not that hard, but needs some changes from you:

For starters, your posts (with class post) are all embedded in a div (class post). The latter should/could be changed to id (<div id="post"> or something else altogether.

Next you can apply some code to the class post

.post {
  margin: 5px;
  background-color: #999;
}

that will separate all posts in their own, visible block.

This is the easy way. The example site uses an background image to create the background, but it boils down to the same.

The .post class is automatically added by the_content().

If you change your style.css, around line 317, to this, you’ll get the desired effect.

.post {
  background-color:#999999;
  margin:24px 0;
  padding:5px;
}

The #999999 is just an example, play around with margins and paddings too.

Please edit the previous post and remove that large chunk of code again. It’s annoying to scroll down that far. If you want to post them, use pastebin instead.

Having said that: yes, you changed the correct piece of code.

Just checked your xhtml, and apparently you call a stylesheet from your webroot, called style.css (http://www.city17productions.com/style.css), which is so not WordPress like.

That’s the one that needs changing.
