Since then, I have just set the default images on this blog to <code>display: none</code> and render them as <code>block</code> elements when their specific <code>section</code> is loaded into the DOM visibly.</p> -<p>The example below is remaining the same as it was, to still provide context for this post.</p> -<h2 id="live-demo">Live Demo</h2> -<p>Before we jump head first into the details, let’s take a look at what we will be creating:</p> -<p>Pretty neat, eh? Well let’s get into the nitty gritty.</p> -<h2 id="the-code">The Code</h2> -<p>Personally, I place everything into a <code>figure</code> element to keep things contained and clean - but this isn’t required by any means. We then include our <code>img</code> and <code>figcaption</code> elements. That’s it.</p> -<pre><code><figure> - <img src="/placeholder-image.webp" onclick="this.src='https://res.cloudinary.com/bradtaunt/image/fetch/q_auto:low/v1570124593/https://uglyduck.ca/public/images/aqua-ui-css-buttons.webp'" alt="Aqua UI buttons"> - <figcaption><b>Click the placeholder to load in the real image</b><br> - Example Dribbble shot for testing. Feel free to click the default image in order to load the correct Dribbble source. - <a href="https://res.cloudinary.com/bradtaunt/image/fetch/q_auto:low/v1570124593/https://uglyduck.ca/public/images/aqua-ui-css-buttons.webp">View full size image</a>. - </figcaption> -</figure> -</code></pre> -<h3 id="the-image-element">The Image Element</h3> -<p>This is where the <em>magic</em> happens. By default all images will target the default placeholder image: <code>placeholder-image.webp</code>. This image is just 16KB in size and only needs to load in once.</p> -<p>Next we include an inline <code>onclick</code> attribute, which targets the current image’s <code>src</code> attribute and changes it based on the URL provided. (Note: I use Cloudinary for my blog’s image storage, but you could even host your images relative to your root directory if you wanted)</p> -<p>Now when a user clicks on the placeholder image, the inline <code>onclick</code> pulls in the correct image in it’s place.</p> -<h3 id="disabled-javascript">Disabled JavaScript</h3> -<p>For users who have JavaScript blocked or disabled we have a decent backup. By including a direct link to the image URL in the <code>figcaption</code> element, we give the user the ability to still view the image in a separate browser tab.</p> -<p>You could get extra fancy and include some <code>noscript</code> tags in your project that maybe render a different placeholder image mentioning they have JavaScript disabled etc, but for my needs that would be overkill.</p> -<h2 id="cool---but-why-do-this">Cool - But Why Do This?</h2> -<p>Bandwidth is a limited resource for a lot of users around the world. As designers and developers it’s best to respect this fact and only load in elements as the user <em>requires</em> them. Every little bit helps.</p> -<footer role="contentinfo"> - <h2>Menu Navigation</h2> - <ul id="menu"> - <li><a href="/">Home</a></li> - <li><a href="/projects">Projects</a></li> - <li><a href="/uses">Uses</a></li> - <li><a href="/wiki">Wiki</a></li> - <li><a href="/resume">Resume</a></li> - <li><a href="/colophon">Colophon</a></li> - <li><a href="/now">Now</a></li> - <li><a href="/donate">Donate</a></li> - <li><a href="/atom.xml">RSS</a></li> - <li><a href="#top">↑ Top of the page</a></li> - </ul> - <small> - Built with <a href="https://barf.btxx.org">barf</a>. <br> - Feeds: <a href="/atom.xml">Atom</a> & <a href="/rss.xml">RSS</a><br> - Maintained with ♥ for the web. <br> - Proud supporter of <a href="https://usefathom.com/ref/DKHJVX">Fathom</a> & <a href="https://nextdns.io/?from=74d3p3h8">NextDNS</a>. <br> - The content for this site is <a href="https://creativecommons.org/licenses/by-sa/2.0/">CC-BY-SA</a>.<br> The <a href="https://git.sr.ht/~bt/bt.ht">code for this site</a> is <a href="https://git.sr.ht/~bt/bt.ht/tree/master/item/LICENSE">MIT</a>. - </small> -</footer>
