    Using Custom Property “Stacks” to Tame the Cascade

    Since the inception of CSS in 1994, the cascade and inheritance have defined how we design on the web. Both are powerful features, but as authors we’ve had very little control over how they interact. Selector specificity and source order provide some minimal “layering” control, without a lot of nuance – and inheritance requires an unbroken lineage. Now, CSS Custom Properties allow us to manage and control both cascade and inheritance in new ways.

    Introducing Sass Modules

    Sass recently launched a major new feature you might recognize from other languages: a module system. The new syntax will replace @import with @use and @forward – a big step forward for making Sass partials (one of the language’s most used features) more readable, performant, and safe. This article goes…

    Sass Modules, a Primer

    Getting started with @use and @forward

    Dart Sass (the primary Sass implementation) released version 1.23.0 last night with a major new feature: modules. This is a common feature in many languages – but for those of us who primarily write CSS, it can be a big mental shift. Let’s take a look at the basics.

    How to Write Beautiful Sass

    Media Queries & Grid Settings

    Practical media helpers for Susy3

    Most grids change with the viewport – and Susy needs new settings at each breakpoint. Susy3 is designed without mixins for complete flexibility from project to project, but it can be useful to build additional tools and shortcuts as you go. Here are some snippets to help you get started…

    Welcome to Susy3!

    Make grid systems your fallback plan

    We’re excited to introduce Susy 3.0, a major update to our popular grid-math calculator – now more focused and flexible than ever. Susy was designed to make layout math easy, without forcing you into generic patterns and ugly markup. But grid systems are on the way out, replaced by real CSS layout specs that live in the browser. With Susy3, we want to help make that a smooth transition.

    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.

    Loops in CSS Preprocessors

    Sass Striped Backgrounds

    Jina asked twitter for Sass advice the other day. She was working on a bit of code to create a rainbow-striped background gradient using any set of arbitrary colors. This is my solution, in the form of a Sass function. This requires Sass 3.2 in order to run.
