Undocumented syntax?

Rails
1

I came across this in api.rubyonrails.org and am wondering if it is a
typo or an undocumented feature. Can someone explain?

<% form_tag ‘/posts’ do -%>

<%= submit_tag ‘Save’ %>

<% end -%>

In particular, I refer to the closing Ruby delimiter ‘-%>’ syntax that
is repeated twice in this example.

Pardon me if this is obvious. I am still new to Ruby.
