In-Browser Performance Linting With Feature Policies
26.2.2020
Here’s a neat idea from Tim Kadlec. He uses the Modheader extension to toggle custom headers in his browser. It also lets him see when images are too big and need to be optimized in some way. This is a great way to catch issues like this in a local environment because browsers will throw an error...

Do This to Improve Image Loading on Your Website
20.2.2020
Jen Simmons explains how to improve image loading by simply using width and height attributes. The issue is that there’s a lot of jank when an image is first loaded because an img will naturally have a height of 0 before the image asset has been successfully downloaded by the browser. Then it needs...
While You Weren’t Looking, CSS Gradients Got Better
14.2.2020
One thing that caught my eye on the list of features for Lea Verou's conic-gradient() polyfill was the last item:
Supports double position syntax (two positions for the same color stop, as a shortcut for two consecutive color stops with the same color)
Surprisingly, I recently discovered most...
Building an Images Gallery using PixiJS and WebGL
12.2.2020
Sometimes, we have to go a little further than HTML, CSS and JavaScript to create the UI we need, and instead use other resources, like SVG, WebGL, canvas and others.
For example, the most amazing effects can be created with WebGL, because...

There is a growing number of things that we have to do to help the browser achieve for peak performance.
Responsive image syntax has several. For example, needing to tell the browser how large the image will be in our layout with the sizes attribute and how big the images are with w descriptors....
Native Image Lazy Loading in Chrome Is Way Too Eager
5.2.2020
Interesting research from Aaron Peters on <img loading="lazy" ... >:
On my 13 inch macbook, with Dock positioned on the left, the viewport height in Chrome is 786 pixels so images with loading="lazy" that are more than 4x the viewport down the page are eagerly fetched by Chrome...

Simple Image Placeholders with SVG
27.1.2020
A little open-source utility from Tyler Sticka that returns a data URL of an SVG to use as an image placeholder as needed.
I like the idea of self-running utilities like that, rather than depending on some third-party service, like placekitten or whatever. Not that I'd advocate for feature...
Flexible Captioned Slanted Images
25.1.2020
The end result of Eric Meyer's tutorial on creating this row of slanted images is pretty classy. But it's more about the journey than the destination (there isn't even really an isolated demo for it). Eric does an amazing job at talking it through like a thought process.
We did that recently, only...
What’s the Difference Between Width/Height in CSS and Width/Height HTML attributes?
24.1.2020
Some HTML elements accept width and height as attributes. Some do not. For example:
<!-- valid, works, is a good idea --<img width="500" height="400" src="..." alt="..."<iframe width="600" height="400" src="..."</iframe<svg width="20" height="20"</svg<!-- not valid...

Adding Dynamic And Async Functionality To JAMstack Sites

Jason Lengstorf:
Here’s an incomplete list of things that I’ve repeatedly heard people claim the JAMstack can’t handle that it definitely can:
Load data asynchronously
Handle processing files, such as manipulating images
Read from and write to a database

PHP Templating in Just PHP
26.12.2019
With stuff like template literals in JavaScript and templating languages, like JSX, I've gotten used to wanting to write my HTML templates in one nice chunk and sprinkling in variables wherever I need them.
I had a situation where I needed to do that in "raw" PHP the other day, so I'm just...
Freak Flags
11.12.2019
I don't see image sprites used that much anymore, but it's still a good technique for reducing downloaded decorative image assets when you have multiple on a page. The big idea is combining all the graphics into one and then shifting around the size and background-position to reveal one at...
Firefox 71: First Out of the Gate With Subgrid

A great release from Firefox this week! See the whole roundup post from Chris Mills. I'm personally stoked to see clip-path: path(); go live, which we've been tracking as it's so clearly useful. We also get column-span: all; which is nice in case you're one of the few taking advantages of...
