Give form a CSS class using simple_form_for

css ruby-on-rails ruby-on-rails-3 class simple-form

this would work

<%= simple_form_for @admin_artist, :html=> { class: 'foobarbaz' } do |f| %>

css ruby-on-rails ruby-on-rails-3 class simple-form

You should use :html like this:

<%= simple_form_for @admin_artist, :html => { role: 'form', class: 'foobarbaz' } do |f| %>
