Loops in CSS Preprocessors

Over the last decade, Responsive Web Design and Object Oriented CSS have grown from exciting new trends into the foundations of modern, component-driven web design. But our medium is not done evolving.

In CSS, there are compound selectors and also complex selectors, and I never remember which is which. Do you need to learn the difference? Probably not. But I’m tired of looking it up.

The other day, I posted an article about implementing webmentions on this site. Today, I’m battling an endless stream of spam in my mentions.

I’m really into the IndieWeb, or the ideas behind it. I like to own my data, I like a space to play and experiment, I like the idea of syndicating content to be read/experienced in a variety of formats. I love microformats, and RSS feeds, and… wait… how do webmentions work?

Cascade & Inheritance Level 5 defines Cascade Layers – allowing authors to define explicit contained layers of specificity.

Declarative controls for presentational state

Cascade layers are a new CSS feature that allows us to define explicit contained layers of specificity.

Cascade & Inheritance Level 5 defines Cascade Layers – allowing authors to define explicit contained layers of specificity.

CSS Containment Level 3 defines Container Queries and container-relative units – allowing authors to build more intrinsic responsive components without knowledge of the overall layout.

Cascade & Inheritance Level 6 defines scoped styles – allowing authors to provide bounded ranges for selector-matching, and give priority to more ‘proximate’ scope origins.

I was Interviewed by Rachel Andrew for the web.dev Designcember (and finally got around to posting a link here)

Miriam talks to Now What? about why the internet looks the way it does, why designers and developers need to collaborate and how the future of the web must be built around inclusivity and respect.

We discuss the role of the ‘design engineer’ and what it means for workflows, collab with their product team, and the end-user experience.

A podcast focusing on front end development but also covering a wide range of web development and design topics. We talked about CSS, Sass, and work being done in the W3C CSS Working Group.

New CSS proposals like Container Queries, Cascade Layers, Scoped Styles, and Nesting are all aimed at improving the way we write responsive components and design systems.

Igalia’s Brian Kardell sits down to chat with Miriam and Rachel Andrew about who works on standards, and who pays for that work.

In this episode of Syntax, Scott and Wes talk with Miriam about all things CSS – container queries, layers, scoping, and more!

I talk with Claire and Steph about my journey into webdev and onto the CSSWG, what I find frustrating about how others use CSS, and the three specs I’m working on.

Working on a new CSS feature like Container Queries, one of the most important considerations is to ensure a “migration path” – a way for developers to start integrating the new code, without breaking their sites on legacy browsers.

I chat with Bruce Lawson & Vadim Makeev about Sass & Susy, CSS Layers & compatibility, Container Queries, and the CSS Working Group.

Starting a new season of the Smashing Podcast with a look at the future of CSS. What new specs will be landing in browsers soon? Drew McLellan talks to Miriam to find out.

Media-queries allow an author to make style changes based on the overall viewport dimensions – but in many cases, authors would prefer styling modular components based on their context within a layout.

CSS Custom Properties (aka Cascading Variables) have gained broad browser support since 2015 – but what are they good for, and why do we need them?

“What is one thing you learned about building websites this year?”

I join Ari, Ben, and Tessa to talk about getting into CSS from other languages, the absurdly massive problem CSS is designed to solve, and the mental model behind the language.

As I spend more of my time working on the CSS language, I wanted a place to take notes and explore new ideas in the open.

How do we write code that is modular & maintainable, in a language designed to be systematic & contextual?

The Cascade makes CSS unique – forcing us to revisit even the most common programming feature: the variable.

The web is designed to work across platforms, devices, languages, and interfaces – but how can we possibly design for that unknown and always-changing canvas?

Learn how design engineering brings together form and function.

Don’t let the declarative syntax fool you – CSS is a powerful and dynamic programming language.

From the very start, “web design” has posed a nearly impossible paradox.

CSS Custom Properties allow us to manage and control both cascade and inheritance in new ways.

From building beautiful sites to maintaining complex design systems across multiple applications, CSS is the web-language of design.

“What about building websites has you interested this year?”

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.

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.

Why waste your time on half-measures? Make your site THE MOST NORMALEST with this ULTIMATE CSS RESET.

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 of code.

I drop by the show to talk about Sass in 2019, design tokens, Oddbird, unused CSS, new CSS properties, and Dave & Chris’ explanation of revert.

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.

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.

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.

The web is designed to work across platforms, devices, languages, and interfaces – but how can we possibly design for that unknown and always-changing canvas?

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.

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.

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?!

Sass recently launched a new module system. The new syntax will replace @import with @use and @forward – a big step forward for making Sass partials more readable, performant, and safe.

Love it or hate it, CSS is weird: not quite markup, not quite programming in the imperative sense, and nothing like the design programs we use for print. How did we get here?

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!

A project-manager’s reflections on human-centered problem-solving, client communication, and user feedback in agile web development.

In the CSS naming-convention arms race to lowest specificity, I’ve decided to only use universal * selectors. I call it F*CSS.

Style Guides & Pattern Libraries are great tools for documenting the relationships between code and design, but beautiful docs are only half the battle.

We start by talking about design systems and design tooling – how they differ, and the problems they solve.

Pushing past the “variable” metaphor, CSS Custom Properties can provide new ways to balance context and isolation in our patterns and components.

Inspired by Robin Rendle, I demonstrate some of my early experiments combining CSS Grids and custom properties to create dynamic layouts and data-visualizations.

Viewport units have been around for several years now, with near-perfect support in the major browsers, but I keep finding new and exciting ways to use them. I thought it would be fun to review the basics, and then round-up some of my favorite use-cases.

It feels like CSS Grid has been coming for a long time now, but it just now seems to be reaching a point where folks are talking more and more about it and that it’s becoming something we should learning.
