<h2>Use of margin: auto</h2>
<p>You can set the margin property to auto to horizontally center the element within its container. The element will then take up the specified width, and the remaining space will be split equally between the left and right margins:</p>
<div>
This div will be horizontally centered because it has margin: auto;

<p class="flip" onclick="myFunction()">Click to show panel</p>
<div id="panel">
<p>This panel contains a div element, which is hidden by default (display: none).</p>
<p>It is styled with CSS and we use JavaScript to show it (display: block).</p>
<p>How it works: Notice that the p element with class="flip" has an onclick attribute attached to it. When the user clicks on the p element, a function called myFunction() is executed, which changes the style of the div with id="panel" from display:none (hidden) to display:block (visible).</p>
<p>You will learn more about JavaScript in our JavaScript Tutorial.</p>

<h1>Image Transparency</h1>
<p>The opacity property specifies the transparency of an element. The lower the value, the more transparent:</p>

<h2>Fixed Full-height Side Nav</h2>
<h3>Try to scroll this area, and see how the sidenav sticks to the page</h3>
<p>Notice that this div element has a left margin of 25%. This is because the side navigation is set to 25% width. If you remove the margin, the sidenav will overlay/sit on top of this div.</p>
<p>Also notice that we have set overflow:auto to sidenav. This will add a scrollbar when the sidenav is too long (for example if it has over 50 links inside of it).</p>

<h2>Input fields with black border on :focus</h2>
<p>Here, the input field gets a black border color when it gets focus (clicked on). We have also added the CSS transition property to animate the border color (takes 0.5 seconds to change the color on focus):</p>

<h2>Image Modal</h2>
<p>Here, we use CSS to create a modal (dialog box) that is hidden by default.</p>
<p>We use JavaScript to trigger the modal and to display the current image inside the modal when it is clicked on. Also note that we use the value from the image's "alt" attribute as an image caption text inside the modal.</p>
<p>Don't worry if you do not understand the code right away. When you are done with CSS, go to our JavaScript Tutorial to learn more.</p>
<img id="myImg" src="img_lights.jpg" alt="Northern Lights, Norway" width="300" height="200">
<!-- The Modal -->
<div id="myModal" class="modal">
<span class="close">&times;</span>
<img class="modal-content" id="img01">
<div id="caption"></div>
</div>
<script>
// Get the modal
var modal = document.getElementById('myModal');
// Get the image and insert it inside the modal - use its "alt" text as a caption
var img = document.getElementById('myImg');
var modalImg = document.getElementById("img01");
var captionText = document.getElementById("caption");
img.onclick = function(){
modal.style.display = "block";
modalImg.src = this.src;
captionText.innerHTML = this.alt;
}
// Get the <span> element that closes the modal
var span = document.getElementsByClassName("close")[0];
// When the user clicks on <span> (x), close the modal
span.onclick = function() {
modal.style.display = "none";
