<ul class="grid">
	<li>
		<p>This is a very stylish <a href="#" id="style-1">link</a> that uses a box shadow.</p>	
	</li>
	<li>
		<p><a href="#" id="style-2">This one </a> uses a <code>::before</code> pseudo-element.</p>		
	</li>
	<li>
		<p>The third <a href="#" id="style-3">link style</a> also uses a pseudo-element, but it has alternating transformation origins.</p>
	</li>
	<li>
		<p>By combining two pseudo-elements, we can <a href="#" id="style-4" data-replace="get a link"><span>get a link</span></a> that looks very interesting on mouse hover.</p>
	</li>
	<li>
		<p>Our fifth entry also uses pseudo-elements and transitions <a href="#" id="style-5">multiple</a> CSS properties to achieve a cool hover effect.</p>
	</li>
	<li>
		<p>The sixth and final link style <a href="#" id="style-6">uses background gradients as bottom borders</a> and this approach allows the link to be styled on multiple lines.</p>
