You could use native software like LibremOffice Impress, Powerpoint, Apple’s Keynote, etc. You could also decide to use preexisting web-based apps like Google Slides or an open source project such as RevealJS. All of these are good options.</p> - <p>But thinking more about how overly complex these apps are implemented, it got me wondering if I could quickly code up a presentation slide framework with pure CSS and barely any code.</p> - <p>This is what I came up with:</p> - <h2 id="the-demo">The Demo</h2> - <p><a href="https://codepen.io/bradleytaunt/pen/jOWBJZb">Live CodePen Example</a></p> - <p>Yes, I know this is <em>ugly</em>, but this was created as a barebones skeleton for others to build upon. The demo uses a simple set of <code>radio</code> inputs that correspond to their own individual <code>slide</code> element. The framework looks at the currently <code>checked</code> input, then changes the <code>opacity</code> and <code>z-index</code> of its corresponding slide item. Pretty straightforward stuff!</p> - <p>Let’s break down each piece:</p> - <h2 id="the-html">The HTML</h2> - <pre><code><div class="slider"> <input type="radio" name="pagination" value="1" checked> <input type="radio" name="pagination" value="2"> @@ -59,11 +50,8 @@ </div> </div> </code></pre> - <p>There isn’t a whole lot going on here. We are just including a set of <code>radio</code> inputs (based on how many slides are desired) along with their corresponding <code>slide</code> class elements. You might notice we don’t do anything to specifically target each individual slide item - you’ll see why we don’t need to in the CSS section!</p> - <h2 id="the-css-scss">The CSS (SCSS)</h2> - <pre><code>/* Basic default styles */ .slider { height: 100%; @@ -100,17 +88,13 @@ input[type="radio"]:nth-of-type(5):checked ~ .slide:nth-of-type(5) { .slide:nth-of-type(4) { background: goldenrod; } .slide:nth-of-type(5) { background: pink; } </code></pre> - <p>Again, not much to see here. We use CSS to look down through the DOM for each <code>radio</code> elements slide “partner”. We do this by targeting the <code>nth-of-type</code> on both elements. Simple stuff.</p> - <p>Some drawbacks to this approach:</p> - <ul> <li>You need to manually target each new slide you add (color, styling, content, etc.)</li> <li>Lack of animations might require extra work to implement (maybe 3rd party libraries- ke AOS?)</li> <li>Probably won’t be best for extremely long/complex presentation slides</li> </ul> - <p>That’s it! Hope you enjoy playing around with it.</p> <footer role="contentinfo"> <h2>Menu Navigation</h2> |
