How can I set the CSS class of an element in a Rails view?

Question

How can I set the class of an element in a Rails view's haml?

For example, suppose I want to set the CSS class of a %td% element that's written like this to the "red" class:

%td= book.author

How would this be written?

That looks like Haml.

You can use either %td.red= book.author or %td{:class => "red"}= book.author.

Yes, I'm a total RoR newbie taking a class; I assumed haml is a given?

Not necessarily! Rails can use many templating languages, include ERB (the default), Haml, Slim, and a number of others. Haml is definitely popular though. :)
