I am new to rails and I want my container to be displayed in all pages except about page, I already have created about controller also about page design, and this is my application.html.erb code : 

```
<header>
      <div class="container">
        <div class="col-md-8">
          <% if params[:controller] == 'games' && params[:action] == 'index' %>
            <h1>The GameStore </h1>
          <% end %>
        </div>
      </div>
    </header>
    <section>
    <div class="container">
      <div class="row">
          <div class="col-md-8">

    <%= yield %>
          </div>
          <div class="col-md-4">
            <%= render 'partials/sidebar' %>
          </div>
      </div>
    </div>
  </section>

```
