If there’s connection one thing I’d like readers to take away from this post it’s that font-display: swap is a very good option for users with a fast internet. But its infinite swap period could be frustrating for users on very slow and unstable connections. If you have users viewing your site under these conditions (I’m pretty certain you will at some point in time), then it may be worth considering font-display: fallback or even font-display: optional. Both have a short swap period (or no swap period), meaning once the fallback font is rendered and the 3 second timeout is exceeded, the font won’t change for the rest of the page lifecycle.

Reducing your web pages' size helps with both load time for people with slower internet connections and them having access to your pages in the first place.

Dropdown, navigation button, tooltip, collapsible panel, lightbox, tabs, switch like above…
UI components made in minutes without worried about JavaScript. Only set a few HTML attributes, and code the rest with your CSS skills.

There's an issue in Silicon Valley and I think the technology industry as a whole, we think adding features increases value, while adding features actually decreases the experience and the focus.

Generating social share images with a serverless function and headless browser.

In this post I'll outline 8 image loading optimization techniques to minimize both the bandwidth used for loading images on the web and the CPU usage for image display.

My goal is to improve the user experience and the business outcome day by day. I am still looking for a tool that tells me what to focus on today to make the most significant impact. As this is the perfect time of the year to create a wish list, here is mine.

Tech is always political. The way data is collected and handled is often biased, and many products are neither accessible nor inclusive. Ethical Design Guide is made to share resources on how to create ethical products that don't cause harm.

Alpine.js offers you the reactive and declarative nature of big frameworks like Vue or React at a much lower cost.

Cette chasse aux interstitiels doit être envisagée dans une approche plus globale d’allégement de son site ou de “désencombrement”.

Au-delà de faciliter la navigation, la réduction de la publicité au strict minimum et la suppression des images ou vidéos inutiles (entre autres) permettent de recentrer l’attention de l’utilisateur.

Because it takes time to set up a connection with the Google Fonts domains, and because that connection is needed before the render-blocking CSS can be downloaded, it can delay rendering metrics like Largest Contentful Paint.

Let’s talk about eliminating font stylesheets as a render-blocking resource, and walk through an optimal setup that not only makes Lighthouse happy, but also overcomes the dreaded flash of unstyled text (FOUT) that usually comes with loading fonts. We’ll do all that with vanilla HTML, CSS, and JavaScript, so it can be applied to any tech stack.

Today, ES2017 is the closest to modern syntax and tools such as npm, Babel, webpack, and Rollup have made it possible to configure your build system and write your packages using this syntax. This post covers several approaches, and you should use the easiest option that works for your use case.

We believe that our system, coupled with a complete set of open-source models, would allow upcoming developers and us comprehensively study configurations under which optimizations fail to provide their advertised performance improvements.

Stimulus is a JavaScript framework with modest ambitions. It doesn't seek to take over your entire front-end—in fact, it's not concerned with rendering HTML at all. Instead, it's designed to augment your HTML with just enough behavior to make it shine. Stimulus pairs beautifully with Turbolinks to provide a complete solution for fast, compelling applications with a minimal amount of effort.

Excellent article, documenté et sourcé, sur les études sociolinguistiques explorant le rapport entre la langue écrite et orale, et la pensée, dans le cadre d'une langue inclusive.
