I've noticed that there are very few moms speaking at conferences in our industry. I'd like us to do our little part to make it easier for women to work in technology fields by making web design and development conferences more mom-friendly. This can help all of us, not just the moms.

The Modernizr feature-detection script now includes four tests for flexbox support, which you can use to target browsers with varying levels of support more precisely.

For years the only bit of feedback web developers could get was via alert("{str}") calls. These days we have the web console but, in rare cases, we don’t have a console and alert calls are our only window into a value at a given time. One problem: if an alert sneaks into production code, your […]

The Firefox DevTools underlying code, which is written with JavaScript and HTML, is a complex application. Due to the complexity and amount of work going on, the DevTools team has done everything they can to load as little as possible. Furthermore the team has a system of lazily importing and initializing objects when they’re needed. […]

Over the years I’ve shared how to perform a number of actions with cURL: how to send POST data, how to retrieve headers, follow redirects, check GZIP encoding, and more. Another useful cURL directive is sending the user agent, as some servers respond with different content or headers depending on the user agent. Let’s have […]

We’ve used hex colors for years but 8-digit hexadecimal is still relatively new.

It happens less frequently these days but there are times when we need to accommodate for a HTTP request timing out. The service could be down, under heavy traffic, or just poorly coded, or any host of other issues. Whenever I need to simulate a long HTTP request, I use a bit of PHP to […]

Access management can be a bit of a nightmare, especially when we realize that we rely on a number of different, independent services that power our organizations.

One interesting aspect of working at Mozilla is that Firefox lives in a mercurial repository while several other projects live on GitHub in a git repository. While most focus on either Firefox or another project, I switch between both, leaving me running git commands inside the mercurial repository and hg commands inside git repos. It’s […]

As a huge fan of media on the web, I’m always excited about enhancements to how we can control our media.

Video games are always a fun time, something we desperately need during our COVID lockdown.

I don’t need to tell you how important search engine placement is. You either earn it with quality content, loads of SEO work, paying for placement, or all of the above.

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 developers to cater their design to system theme […]

Two of the most prominent utilities in web development today are ESLint and Microsoft’s Visual Studio Code.

In August, due to a twitter discussion with Molly, and of course while partying on a Saturday night, Dave Gregory and I were looking at whether the Flexible box layout module (still a working draft) is getting close to ready for prime time yet. Our hope was that it will solve some of the frustrations [...]

As you may have read, outside of gradients, you can’t change a background-image with CSS transitions. Or can you? At InControl Conference last week, Greg Rewis spoke about Transitions, Transforms and Animations. A question was asked about showing one background-image on load and transitioning to another in a subsequent pseudo-state. You can always change the [...]

Last night, I was getting a file ready to share with Estelle Weyl, one of my co-presenters for our CSS3 workshop at SXSW11. The page was a silly little demo that used media queries, multiple backgrounds, transitions, generated content, multi-column layout and, well, a unicorn. I had only viewed the file in Chrome since that’s [...]

This morning I awakened with a question in my twitter stream from @deebeefunky. He was frustrated by the fact that when he sets a blur on box-shadow, it shows on two sides of the box. He wants it to show on only one side. Of course, that got me thinking. I did come up with [...]

In 1999, when I started my journey through the interwebs, I had no real idea where it would take me. I barely knew what was possible. I only knew that my brain loved puzzle-type thinking, detective work, research and figuring things out. And I suspected code would access the parts of my mind that love [...]

I ran into a very frustrating bug while using icon fonts on our site at Contatta. A bug I filed last April, and nurtured through the process of getting fixed, didn’t make the Mozilla release notes (though it was included in Firefox 28). Because I feel it’s a very useful solution, I wanted to bring [...]

I’ve been quiet lately. Startup life is busy… and exhausting. Blogging for me has pretty much gone the way of the Dodo. I’m planning to change that.

While implementing the trial automation flows at Contatta, one of my goals was to create an exit survey email for people who did the 30-day trial but had decided not to move to the paid plan. I wanted to send a simple, multiple choice question with the final option being “other,” so trial users could [...]

Yesterday, we had a discussion at work about rems, ems and percentages. I’ve used ems for media queries for years. I’ve used rems for font sizing for a couple of years. I felt like I had a pretty good handle on how it all works. Most of you probably understand the difference, but let’s do [...]
