A Quick Look at the First Public Working Draft for Color Adjust Module 1
Apr 20, 2025 am 09:58 AMSince Apple introduced Dark Mode as a system setting in macOS 10.14 and later in Safari, the topic has dominated discussions. Its potential for innovative design and personalized user experiences is captivating.
This week saw the release of an Editor's Draft and the First Public Working Draft for the Color Adjust Module Level 1 specification. While still a work in progress, its development is fascinating. The specification introduces three new CSS properties, offering greater control over how user agents handle visual rendering based on user preferences.
color-scheme
is the core property. It accepts light
and dark
values, corresponding to Light Mode and Dark Mode system preferences. While other labels might be used (e.g., "Day" and "Night"), the fundamental distinction remains: light versus dark color schemes.
This property has significant implications. It allows style adjustments based on user system preferences, enabling fine-tuned user experiences. Furthermore, declaring this property signals to the user agent that an element is "color-scheme aware," prompting styling adjustments according to the user's preference. Conversely, the auto
value grants the browser complete control, allowing it to determine the color scheme based on system preferences and default styling.
It's important to note the prefers-color-scheme
media feature (currently in the Editor's Draft for Media Queries Level 5), which aids in detecting user preferences and enhancing user experience control. The Color Adjust Module Level 1 Working Draft also suggests using a color-scheme
value within a <meta>
element to indicate color scheme support.
The color-scheme
property includes additional features: the only
keyword, value chaining for preference ordering, and a custom ident keyword. A thorough review is recommended due to its complexity.
The potential of this draft to revolutionize design and decision-making is exciting. And this is just the beginning; two more properties are included:
-
forced-color-adjust
: This allows color scheme support while overriding default user agent stylesheets with custom CSS. There's a note about potential merging withcolor-adjust
. -
color-adjust
: Instead of forcing CSS overrides, this property provides a hint to browsers, enabling color value adjustments based on user preferences and other factors like screen quality or bandwidth. Eric Bailey's work explores potential use cases, accessibility enhancements, and general implementations.
The current draft is expected to expand. This provides an opportunity to acknowledge the W3C's remarkable work, understand the challenges involved, and even contribute to the process. (See Rachel Andrew's advice on contributing.)

There are three ways to selectively include CSS on a specific page: 1. Inline CSS, suitable for pages that are not frequently accessed or require unique styles; 2. Load external CSS files using JavaScript conditions, suitable for situations where flexibility is required; 3. Containment on the server side, suitable for scenarios using server-side languages. This approach can optimize website performance and maintainability, but requires balance of modularity and performance.

CSS blocks page rendering because browsers view inline and external CSS as key resources by default, especially with imported stylesheets, header large amounts of inline CSS, and unoptimized media query styles. 1. Extract critical CSS and embed it into HTML; 2. Delay loading non-critical CSS through JavaScript; 3. Use media attributes to optimize loading such as print styles; 4. Compress and merge CSS to reduce requests. It is recommended to use tools to extract key CSS, combine rel="preload" asynchronous loading, and use media delayed loading reasonably to avoid excessive splitting and complex script control.

CSSCounters is a tool for creating automatic numbers. 1. Basic usage: define and operate counters through counter-reset and counter-increment, such as "SectionX." before h2. 2. Advanced usage: Use nested counters to create complex numbers, such as chapter and section numbers. 3. Notes: Ensure the counter is reset correctly, optimize performance, and simplify counter logic. 4. Best practice: clear naming, define counters in CSS, and use counter-increment and counter-reset reasonably.
