Answer 1

Adjusted the markup slightly for the tabs, and changed IDs to classes for styling:

<div class="header">
     <h1>City Gallery</h1>
</div>
<div class="nav">
    <ul>
        <li><a href="#section-london">London</a></li>
        <li><a href="#section-paris">Paris</a></li>
    </ul>
</div>
<div id="section-london" class="tab-content">
    <h2>London</h2>
    <p>London is the capital city of England. It is the most populous city in the United Kingdom, with a metropolitan area of over 13 million inhabitants.</p>
</div>
<div id="section-paris" class="tab-content">
    <h2>Paris</h2>
    <p>Paris, France's capital, is a major European city and a global center for art, fashion, gastronomy and culture. Its picturesque 19th-century cityscape is crisscrossed by wide boulevards and the River Seine. </p>
</div>
<div class="footer">Footer</div>

And the jQuery part:

$(document).ready(function () {
    $('.nav ul li:first').addClass('active');
    $('.tab-content:not(:first)').hide();
    $('.nav ul li a').click(function (event) {
        event.preventDefault();
        var content = $(this).attr('href');
        $(this).parent().addClass('active');
        $(this).parent().siblings().removeClass('active');
        $(content).show();
        $(content).siblings('.tab-content').hide();
    });
});
