Basic webpage structure
&lt;div id="Header"&gt;


HTML 5 introduces the &lt;header&gt; element.

          &lt;h1 align="center"&gt;


Don't use presentational attributes, like align, use CSS. 

          &lt;img src="Images/fellows.gif" width="150" height="39" longdesc="Images/fellows.gif"&gt;


The alt attribute is mandatory. If the text that follows it duplicates the information in the image, then use alt="".

The longdesc attribute has been removed from HTML 5. In HTML 4 it should point to an HTML document that describes the image (for people who cannot see it), not the image itself.

          &lt;font size="12"&gt;Fellows and Fullwood&lt;/font&gt;


The &lt;font&gt; element is obsolete and should not be used (and I'm pretty sure 12 isn't a valid size for it anyway). Use CSS. 

          &lt;/h1&gt;
      &lt;/div&gt;
      &lt;div id="nav"&gt;


HTML 5 introduces the &lt;nav&gt; element.

          --&gt;&lt;li&gt;&lt;a href="#"&gt;Home&lt;/a&gt;&lt;/li&gt;&lt;!--
          --&gt;&lt;li&gt;&lt;a href="#"&gt;About Us&lt;/a&gt;&lt;/li&gt;&lt;!--
          --&gt;&lt;li&gt;&lt;a href="#"&gt;News&lt;/a&gt;&lt;/li&gt;&lt;!--
          --&gt;&lt;li&gt;&lt;a href="#"&gt;Careers&lt;/a&gt;&lt;/li&gt;&lt;!--
          --&gt;&lt;li&gt;&lt;a href="#"&gt;Contact Us&lt;/a&gt;&lt;/li&gt;
          &lt;/u1&gt;
      &lt;/div&gt;
      &lt;div id="Main"&gt;


HTML 5 introduces &lt;main&gt;

        &lt;h2&gt;Contact us&lt;/h2&gt;&lt;form  action=""


You can omit the action attribute entirely if you want to resolve to the current URI.

         method="POST" enctype="multipart/form-data"&gt;
          &lt;div align="center"&gt;
            &lt;p&gt;
              &lt;input type="hidden" name="action" value="submit"/&gt; 
            &lt;/p&gt;


Most of the paragraphs in this form at dubious at best but this is just wrong. There is no content for the user at all, and certainly no paragraph.

            &lt;p&gt;Your name:&lt;br&gt;


Please learn to love labels 

            &lt;input name="name" type="text" value="" size="30"/&gt;
              &lt;br /&gt; 


In general, prefer container elements and CSS margins/paddings to hard line breaks. &lt;br&gt; is most useful when line breaks are a significant part of content which is otherwise continuous (such as street addresses or poetry). 

      &lt;div id="Footer"&gt;
          &lt;p&gt;&amp;copy;Copyright Fellows and Fullwood 2014.&lt;/p&gt;
      &lt;/div&gt;


HTML 5 introduces the &lt;footer&gt; element.
