html navigation bar
<!-- How to create a navigation bar:
This is the html file:
Put the class="active" in the html file/page you are coding in
(e.g. put the class="active" in the Home.html file)
To position a page link to the right do class="right"
-->
<body>
<ul class="topnav">
<li><a class="active" href="Home.html">Home</a></li>
<li><a href="Page1.html">Page1</a></li>
<li><a href="Page2.html">Page2</a></li>
<li class="right" ><a href="About.html">About</a></li>
</ul>
</body>
<!-- This is the css file:
(have a play with the colours and features!)-->
ul.topnav {
list-style-type: none;
margin: 0;
padding: 0;
overflow: hidden;
