<body>
<p>This example demonstrates the CSS selector [attribute="value"], specifically [target="_blank"], which selects all 
links that open in a new tab. Such links are styled orange, while regular links are blue. Try the difference between 
the links below:</p>

<button class="btn-download" onclick="window.print()">Download PDF</button>
<a href="https://vadnica.org" target="_blank">Open page in a new tab</a>
</body>
</html>
