Alignment off

I am a novice doing your rails programming course. I am looking at the edit form page and have realised that the alignment of the Email field is centred, while all of the rest is left aligned. I guess it has something to do with the 'Form_for' code but can't work it out.

The code is below. Could you advise please.

<h2>Edit <%= resource_name.to_s.humanize %></h2>

<%= form_for(resource, :as => resource_name, :url => registration_path(resource_name), :html => { :method => :put }) do |f| %> <%= devise_error_messages! %>

<div><%= f.label :email %><br /> <%= f.email_field :email, :autofocus => true %></div>

<%# if resource.class.reconfirmable && resource.unconfirmed_email.present? %> <!-- <div>Currently waiting confirmation for: --> <%#= resource.unconfirmed_email %></div> <%# end %>

<div><%= f.label :password %> <i>(leave blank if you don't want to change it)</i><br /> <%= f.password_field :password, :autocomplete => "off" %></div>

<div><%= f.label :password_confirmation %><br /> <%= f.password_field :password_confirmation %></div>

<div><%= f.label :current_password %> <i>(we need your current password to confirm your changes)</i><br /> <%= f.password_field :current_password %></div>

<div><%= f.submit "Update" %></div> <% end %>

<h3>Cancel my account</h3>

<p>Unhappy? <%= link_to "Cancel my account", registration_path(resource_name), :data => { :confirm => "Are you sure?" }, :method => :delete %>.</p>

<%= link_to "Back", :back %>
