<h2>HTML</h2>
<p>In this tutorial, we are building a dropdown navigation menu. For this we are using simple HTML and CSS without JavaScript or some dynamic and advanced frameworks. To behave as a dropdown menu, we are using the feature of checkbox which can be checked and unchecked. </p>
</section>

<section id="CSS" class="content">
<h2>CSS</h2>
<p>This dropdown navigation Menu is a simple example built with Pure CSS and HTML. Since the button doesn't allow unclickable property without using JavaScript, we are manipulating the CSS styles of the checkbox button to make it behave as a dropdown navigation menu.</p>
</section>

<section id="JavaScript" class="content">
<h2>JavaScript</h2>
<p>In this tutorial, we are building a beautiful and responsive dropdown navigation menu without using Javascript. We are using media queries for responsiveness changing the CSS on several breakpoints  to make it responsive on varying width.</p>
