Adding show/hide to my div tags
<p>so I got 4 div tags, with id's - <code>content1</code>; <code>content2</code>; <code>content3</code> and <code>content4</code>.
at start, <code>content1</code> is only shown, and all other 3 contents are invisible, and I got menu with links, <code>#content1</code>, <code>#content2</code>, <code>#content3</code>, <code>#content4</code>.<br>
So I need to create, when somebody clicks for example on <code>content3</code> link, current content will hide and <code>content3</code> content will show up, same to all other contents.</p>

<p>My question - I know how to make show/hide with one element, but I haven't created anything with 2 or more elements, so maybe you could help me create it?</p>
