Items that have been surely needing of updates for the last couple of years.</p> +<h2>Introductions</h2> +<p>I've always been a sucker for Edward Tufte's incredibly simple, yet powerful design work used in his books and handout projects. So, in 2018 I released a Tufte CSS inspired Jekyll theme for the open source community. I called it <a href="https://et-jekyll.netlify.com">ET-Jekyll</a> (so original, I know). Tufte CSS was a great starting point for my Jekyll theme, but there were areas I thought could use some minor improvements.</p> +<p>Feel free to read all the details on the design here: <a href="https://et-jekyll.netlify.com/et-jekyll-theme/">ET-Jekyll theme details</a></p> +<h2>Minor Fixes One Year Later</h2> +<p>When I finally circled back to this project recently, I noticed some minor issues that could be improved right away with little to no effort. Let's see the changes made at a glance:</p> +<ul> +<li>Sidenote, marginnote and figure element restyling (flexbox)</li> +<li>Table styling fixes (right alignment issues)</li> +<li>Switch MathJax over to SVG embeds (performance fixes)</li> +<li>Simplify HTML skeleton of main pages, remove overkill classes</li> +<li>Remove lazysizes.js to save on load times</li> +<li>Fallback on font-display for font loading</li> +<li>Inline all CSS for faster initial paint</li> +<li>Minor link :hover coloring (accessibility)</li> +<li>Add missing image link on example page</li> +<li>Update details post structure</li> +</ul> +<p>You can view all the updates in more detail <a href="https://github.com/bradleytaunt/ET-Jekyll/commit/254f9e8f28764c9525ba7405bbbfa18a3867d241">here</a>.</p> +<p><strong>So what did this accomplish?</strong> Let's break it down below.</p> +<h2>First Contentful Paint & Input Delay</h2> +<p>The new improvements have netted the theme a savings of 300ms on first paint and reduced the input delay by 150ms. Small wins - but wins nonetheless since every millisecond counts.</p> +<p><figure> + <img src="/public/images/tufte-first-paint.webp" alt="First paint comparison" /> + <figcaption>First contentful paint savings: 300ms (<a href="/public/images/tufte-first-paint.webp">direct link to image)</a></figcaption> +</figure></p> +<p><figure> + <img src="/public/images/tufte-input-delay.webp" alt="Input delay comparison" /> + <figcaption>Reduction in input delay: 370ms down to 220ms (<a href="/public/images/tufte-input-delay.webp">direct link to image</a>)</figcaption> +</figure></p> +<h2>Fixing Render Blocking Items</h2> +<p>The original theme reported a few items that were slowing down the initial render for the end-users:</p> +<table> +<tr><th>URL </th><th>Size (KB) </th><th>Savings (ms) </th></tr> +<tr><td>/css/style.css </td><td>2.0 </td><td>150 </td></tr> +<tr><td>/lazysizes@4.0.1/lazysizes.js </td><td>5.0 </td><td>960 </td></tr> +<tr><td>MathJax.js?config=TeX-MML-AM<em></em>HTML </td><td>18.0 </td><td>1,260 </td></tr> +</table><p>These items were resolved by:</p> +<ul> +<li>Rendering all styling inline (therefore removing the extra HTTP request)</li> +<li>Removing the lazysizes library altogether (browsers plan to support lazy loading natively in the future) +<ul> +<li>The future plan is to integrate something like Cloudinary for out-of-the-box image processing</li> +</ul> +</li> +<li>Switch over MathJax to render equations as embedded SVGs (saves on bandwidth rendering an entire extra typeface)</li> +</ul> +<h2>Lighthouse Numbers</h2> +<p>Though it might not look like much, the updated theme receives a 4-point boost to its performance rating during a Lighthouse audit. Having a perfect score would be even better, but I can settle for 2-points under (for now).</p> +<h4>Old Version</h4> +<table> +<tr><th>Performance </th><th>Accessibility </th><th>Best Practices </th><th>SEO </th></tr> +<tr><td>94 </td><td>100 </td><td>100 </td><td>100 </td></tr> +</table><h4>New Version</h4> +<table> +<tr><th>Performance </th><th>Accessibility </th><th>Best Practices </th><th>SEO </th></tr> +<tr><td>98 </td><td>100 </td><td>100 </td><td>100 </td></tr> +</table><h2>Final Thoughts</h2> +<p>This project could still use some more fine-tuning, but for now I'm fairly happy with the outcome. Even the smallest boost in performance and rendering time makes me feel like I accomplished something worthwhile. </p> +<p>Please don't hesitate to suggest features or point out any issues you happen to stumble across if you plan to use ET-Jekyll.
