22.10.2021
It’s not uncommon for my front-end workflow to go something like this:
Work on thing.
See that thing in an automatically refreshed browser.
See something wrong with that thing.
Inspect and correct the thing in DevTools.

Should DevTools teach the CSS cascade?
22.5.2021
Stefan Judis, two days before I mouthed off about using (X, X, X, X) for talking about specificity, has a great blog post not only using that format, but advocating that browser DevTools should show us that value by …

Core Web Vital Tooling
26.10.2020
I still think the Google-devised Core Web Vitals are smart. When I first got into caring about performance, it was all: reduce requests! cache things! Make stuff smaller! And while those are all very related to web performance, they are abstractly related. Actual web performance to users are things...
Make Your Own Dev Tool
29.9.2020
Amber Wilson on making bookmarklets to help yo-self. She shows off one that injects an accessibility script — I like this approach, as it means you don’t have to maintain the bookmarklet, just the script it links to). Another example runs some code contained right in the link. The result...

There are a number of these desktop apps where the goal is showing your site at different dimensions all at the same time. So you can, for example, be writing CSS and making sure it’s working across all the viewports in a single glance.

New in Chrome: CSS Overview
1.7.2020
Here’s a fancy new experimental feature in Chrome! Now, we can get an overview of the CSS used on a site, from how many colors there are to the number of unused declarations… even down to the total number of defined media queries.

Understand why CSS has no effect with the Inactive CSS rules indicator in Firefox DevTools
5.6.2020
It’s useful when DevTools tells you that a declaration is invalid. For example, colr: red; isn’t valid because colr isn’t a valid property. Likewise color: rd; isn’t valid because rd isn’t a valid value. For the most part, a browser’s DevTools shows...
