Instance Method Details

#page_classString Also known as: generate_content_class_names

Returns a value for the "class" attribute unique to this controller/action pair. This can be used to target styles specifically at this action or controller. For example, if the current action were EntryController#show,

%div{:class => page_class} My Div

would become

<div class="entry show">My Div</div>

Then, in a stylesheet (shown here as Sass), you could refer to this specific action:

.entry.show
  font-weight: bold

or to all actions in the entry controller:

.entry
  color: #00f

Returns:

  • (String)

    The class name for the current page
