title: How to style buttons in Ruby on Rails
body: <p>Button is as follows:</p>
  
  <pre><code>    &lt;%= render 'follow_form' if signed_in? %&gt;
  </code></pre>
  
  <p>In follow_form:</p>
  
  <pre><code>    &lt;%= render 'follow' %&gt;
  </code></pre>
  
  <p>In follow.html.erb:</p>
  
  <pre><code>    &lt;%= form_for current_user.relationships.build(:followed_id =&gt; @user.id),
           :remote =&gt; true do |f| %&gt;
      &lt;div&gt;&lt;%= f.hidden_field :followed_id %&gt;&lt;/div&gt;
      &lt;div class="actions"&gt;&lt;%= f.submit "Watch" %&gt;&lt;/div&gt;
      &lt;% end %&gt;
  </code></pre>
  
  <p>How would I style that with CSS? </p>
