We worked with Mozilla Developer Relations to research & address developer needs around open web standards, CSS features, accessibility, Firefox, and developer tools. Over the course of six months, we released 30 videos to nearly twenty thousand subscribers.

—Jen Simmons, Designer & Developer Advocate
@TerribleMia does not only explain "why CSS is how it is" but also neatly summarizes the basic principles of what make the Web the Web. If you know those principles, many implementation details will be less baffling to you.

For quick visual adjustments directly on the page
on Mozilla Developer with Miriam Suzanne on
Have you ever wanted to create more interesting shapes on the web, or flow text around the details of an image? Shape paths can be hard to code without a visual reference, but Firefox provides a shape editor to make it quick and clear.
Just in time for Selectors Level 4
on Mozilla Developer with Miriam Suzanne on
Firefox 69 was the first to implement selector feature queries, but other browsers are following suit. I’ll show you how it works, and how to start using this new feature query right away.
None of the solutions are perfect, but we have some options
on Mozilla Developer with Miriam Suzanne on
Horizontal text overflow has always been difficult to manage on the web. The default visible overflow is designed to make sure content remains accessible no matter the size of a containing box, but it’s not our only option.
Without any JavaScript or "scrolljacking"
on Mozilla Developer with Miriam Suzanne on
When we’re scrolling down a page, or through a gallery of images, snap-targets can help guide us from one section or image to the next. In the past, developers have used JavaScript to hijack scrolling, but now we can manage scroll alignment directly in CSS with only a few lines...
Allow us to be more explicit & expressive about layouts
on Mozilla Developer with Miriam Suzanne on
The display property has been in CSS from the beginning, handling everything from block and inline boxes to list-items and full layout systems like flexbox or grid. Now the display syntax is getting an upgrade to match it’s multiple uses.
Have you ever set a width in CSS, and... nothing happens?
on Mozilla Developer with Miriam Suzanne on
There are a number of property & value combinations that can lead to CSS being inactive, and now Firefox will tell you why. Open the developer tools, and look for the greyed-out property with an info-box on hover.
And subgrid, landing on Dec 3
on Mozilla Developer with Miriam Suzanne on
For years, we’ve struggled to build resilient layouts on the web, but CSS Grid promises to change all that – and you can start using it now, with only a few properties and basic concepts.
and fallbacks for legacy browsers
on Mozilla Developer with Miriam Suzanne on
It’s a common pattern to align form labels and inputs in grid-like layout. I’ll show you how to do it quickly using CSS subgrid, with several quick fallbacks.
and fallbacks for legacy browsers
on Mozilla Developer with Miriam Suzanne on
Card layouts are popular on the web, rows and columns of boxes with similar content. CSS grids can help align those cards, but it’s still be hard to line-up content inside the cards – headers and footers that might need more or less room.
revert do in CSS?
And how is it different from unset or initial?
on Mozilla Developer with Miriam Suzanne on
I’ve often used initial and unset in my CSS – global keywords that can be applied to any property. The difference is small, but important: unset allows inheritance, while initial does not. But then Firefox implemented revert and I was confused – how is this one different from the others?
How can we design for an unknown & infinite canvas?
on Mozilla Developer with Miriam Suzanne on
CSS is the design language of the web – one of three core web languages – but it also seems to be the most contentious and often perplexing. It’s too easy and too hard, too fragile and too resilient. Love it or hate it, CSS is weird: not quite markup...
Powerful New CSS for Styling Bullets, Numbers, and List Markers
on Mozilla Developer with Miriam Suzanne on
When you create lists in HTML, browsers add bullet-points or numbers we call list markers. Now CSS gives us the tools to style those list markers, and even create our own!
