title: Browser compatibility while using anchor tag
body: <p>I am using <code>anchor tag</code> for linking my welcome page to my main page. It is working on chrome but not in <code>mozilla</code>.</p>
  
  <p>Code:</p>
  
  <pre><code> &lt;div id="wel1"&gt;&lt;h1&gt;WELCOME TO ASSESMENT ENGINE&lt;/h1&gt;&lt;/div&gt;
   &lt;div id="wel2"&gt;
       &lt;div id="wel3"&gt;&lt;p id="wel4"&gt;Instruction:&lt;/p&gt;&lt;br&gt;
          &lt;p id="lang"&gt;Total number of questions : 5.&lt;br&gt;&lt;br&gt;
              Time alloted : 3 minutes.&lt;br&gt;&lt;br&gt;
              Each question carry 10 mark, no negative marks.&lt;/p&gt; 
       &lt;/div&gt;
       &lt;div id="wel5"&gt;
          &lt;p id="wel4"&gt;
             Note:&lt;/p&gt;&lt;br&gt;
          &lt;p &gt;
            &lt;ul&gt;
              &lt;li&gt;&lt;p&gt;Click the 'Submit Test' button given in the bottom of this page to Submit your answers.&lt;/p&gt;&lt;/li&gt;
              &lt;li&gt;&lt;p&gt;Test will be submitted automatically if the time expired.&lt;/p&gt;&lt;/li&gt;
              &lt;li&gt;&lt;p&gt;Don't refresh the page.&lt;/p&gt;&lt;/li&gt;
            &lt;/ul&gt;
          &lt;/p&gt;
       &lt;/div&gt;
       &lt;a href="as.html"&gt;&lt;button id="bu"&gt;START THE TEST&lt;/buttton&gt;&lt;/a&gt;  
   &lt;/div&gt;
  </code></pre>
