title: Understanding MVC tags for nopCommerce
body: <p>I am new to MVC , and in the application i downloaded and trying to debug i see this mark up</p>
  
  <pre><code>@Html.Widget("body_start_html_tag_after")
  @Html.Partial("_Notifications")
  @Html.Action("AdminHeaderLinks", "Common")
  </code></pre>
  
  <p>What does this mean?, @Html.Partial where can I find where the value "body_start_html_tag_after") is defined ?</p>
  
  <p>And this one:</p>
  
  <pre><code>&lt;div class="master-wrapper-main"&gt;
      @RenderBody()
  &lt;/div&gt;
  </code></pre>
  
  <p>Where can i find what <code>@RenderBody</code> does?, this is in a <code>.cshtml</code> file.</p>
