Chapter 3: The Website

Nailing the Perfect Contrast Between Light Text and a Background Image


Have you ever come across a site where light text is sitting on a light background image? If you have, you’ll know how difficult that is to read. A popular way to avoid that is to use a transparent overlay. But this leads to an important question: Just how transparent should that overlay...

Pausing a GIF with details/summary


Steve Faulkner has a clever idea here. You can show an (animated) GIF and overlay a pause/play button on top of it — which is really a <details>/<summary> element. When toggled, a (non-animated) JPG inside covers the GIF, effectively “pausing” it. Adrian Roselli calls...

On dependency


Rob Weychert: But I can’t host your site or even my own site. I didn’t build the CMS. Other people made the hardware and software I use to generate and optimize images. Other people made the fonts. Other people standardized the digital formats for those images and fonts. I didn’t write the HTML...

Lazy Loading Images in Svelte


One easy way to improve the speed of a website is to only download images only when they’re needed, which would be when they enter the viewport. This “lazy loading” technique has been around a while and there are lots of great tutorials on how to implement it. But even with all the resources...

Lazy Load IFRAMEs


We’ve known for a decade that lazy loading resources like JavaScript, CSS, and especially images is a massive performance win for web pages. At first we used tricks and JavaScript to do the lazy loading, but more recently native image lazy loading has debuted in browsers. Did you know that...

WebP Image Support Coming to iOS 14


Apple announced a ton of new updates at yesterday’s WWDC20 keynote address, from new hardware to updated applications. There’s lots to gawk at and enough device-envy to go around. But there’s one little line in the Safari 14 Beta release notes that caught my eye: Added WebP image...

Easing Animations in Canvas


The <canvas> element in HTML and Canvas API in JavaScript combine to form one of the main raster graphics and animation possibilities on the web. A common canvas use-case is programmatically generating images for websites, particularly games. That’s exactly what I’ve done in a website...

Comparing Social Media Outlets for Developer Tips


As a little experiment, I shared a development tip on three different social networks. I also tried to post it in a format that was most suitable for that particular social network: On Twitter, I made it a thread. On Instagram, I made it a series of images. On YouTube, I made it a video. How...

Static Hoisting


The other day in “Static or not?” I said: […] serving HTML from a CDN is some feat. What I meant is that serving resources like images, CSS, and JavaScript from a CDN is fairly straightforward. The industry at large has been doing that for many years. An asset with a URL can...

How to Display Mode-Specific Images


Now that we have most of the basics of HTML and CSS in the browser, we’ve begun implementing new features that I would consider “quality of life” improvements, many of which have been inspired by mobile. One great example is the CSS prefers-color-scheme media query, which allows...

Cloudinary Studio


I knew that Cloudinary worked with video as well as images but, the other day, I was curious if Cloudinary offered a video player embed just like other video hosts do (e.g. YouTube, Vimeo, etc). Like an <iframe> that comes with a special player. I was curious because, as much as...
