Alright, but where are you defining ’single’? :)

They just need to be in a view directory. For example, _post.html.erb would most likely be in app/views/posts.

To make your CSS a little DRYer, you can space delimit multiple class names like

…

instead of

Then in your CSS you can do

# Style anything single (posts and non-posts) in a red box
.single {
border: solid thin red;
}

# Style all posts (single or collections) with a small font
.post {
font-size: small;
}

# Style single posts with a small blue font in a red box
.single.post {
color: blue;
}

Yeah, I like using the “body id=” to style the same elements differently on each page. It’s a great dry way of coding. Particularly useful for navigation and showing the user their nav selection.

On topic: I love the use of looping through a collection in a partial. Nice write up John.

That’s true. I just like to leave body ids for things like matching the current page to the highlighted item in the nav. Since you can only apply one ID per page, but can apply multiple classes, I thought a body class might work better in this case.

@Jaime – Body selectors would work perfectly fine. I would probably use id’s as opposed to a class because they will be a unique element that will only change page to page.

What about using more specific selectors so that you don’t have to apply a class to the post. For example, on the single post page, you would apply a the “single” class to the body of the page (and “post” class to the post div), and then “body.single div.post” to select your post element in the CSS. And then apply a “multi” class to the body of the page with multiple posts, and then “body.multi div.post” to select the element in CSS.

This leaves the logic out of the presentation layer.

All that said, yours is still a good tip that could be put to good use.
