Issue in build simple Ruby Application - bootstrap

I seem to be getting quite a bit of different code, which with Ruby 2.0 and Rails 4.0 makes some sense. I am getting some weird CSS issues (assuming because of Bootstrap) but the big one is when i am editing the _form.html.erb file that corresponds to the "Installing Simple Forms" video. My text box is small and out of alignment and the bootstrap submit button does not work either. When i compare out HTML code, it looks different. An example is in the textarea tag the instructor has col: 40 and row :20, where mine just does not have any reference to this. Any help is appreciated as well as what would be best to just override it with a CSS file if possible.

Here is the code for my _form.html.erb:

<%= simple_form_for(@status, html: {class: "form-horizontal"}) do |f| %> <% if @status.errors.any? %> <div id="error_explanation"> <h2><%= pluralize(@status.errors.count, "error") %> prohibited this status from being saved:</h2>

  <ul>
  <% @status.errors.full_messages.each do |msg| %>
    <li><%= msg %></li>
  <% end %>
  </ul>
</div>

<% end %>

<%= f.input :content %>

<div class="form-actions"> <%= f.button :submit %> </div> <% end %>
