+<p>2021-04-12</p>
+<p>After recently jumping back to Jekyll for my personal blog, I decided to take a closer look at how I was supporting <code>dark mode</code> for my visitors. I was using the proper CSS query to target those who had system-wide dark mode enabled, but I found that the code had far too many caveats and targeted too many custom classes.</p>
+<p>So I thought to myself, &#8220;There <em>has</em> to be a simpler way&#8230;&#8221;</p>
+<h2 id="introducing-dark-mode---the-lazy-way">Introducing Dark Mode - The Lazy Way</h2>
+<p>Here is the default dark mode for my current website in all it&#8217;s glory:</p>
+<pre><code>@media (prefers-color-scheme: dark) {
+ body{background:#2d2d2d;filter:invert(1);}
+ img,.cp_embed_wrapper,pre{filter:invert(1);}
+}
+</code></pre>
+<p>Not much to look at, eh? Well, let&#8217;s still break it down.</p>
+<p>First we set the <code>body</code> to use a nice dark background color (avoid using <code>#000000</code> directly since that can cause some minor eye strain). Next we tell the browser to invert all the child elements by using <code>filter:invert(1)</code>. At this point, you could consider your work done - but there are some edge case elements&#8230;</p>
+<h2 id="images-codepens-code---oh-my">Images, CodePens &#38; Code - Oh My!</h2>
+<p>Most of my articles on this site will include either an image(s), embedded CodePen examples or code snippets directly in the page. For these elements we probably <em>don&#8217;t</em> want to invert their color&#47;text etc. All we need to do is run the filter property on these a second time (<em>after</em> the main <code>body</code> attribute):</p>
+<pre><code>@media (prefers-color-scheme: dark) {
+ img,.cp_embed_wrapper,pre{filter:invert(1);}
+}
+</code></pre>
+<p>Of course, YMMV depending on what other custom elements you want to avoid inverting.</p>
+<h2 id="minor-caveats">Minor Caveats</h2>
+<p>I should mention that since my website doesn&#8217;t use any custom coloring for anchor links, inverting <code>ahref</code> elements works out of the box. Certain projects might still require some custom overrides if the inverted version of a certain custom color looks poor.</p>
+<p>That&#8217;s it - enjoy being lazy!</p>
