Every developer who writes CSS faces a fundamental question: in what order should the properties appear within each rule? This seemingly minor styling decision has sparked years of debate, multiple industry polls, and passionate discussions across the developer community. Whether you're working on a personal project or collaborating with a large team, establishing a consistent approach to CSS property ordering can significantly impact code readability and maintainability.
This guide examines the various methods developers use to organize their CSS properties, explores the poll results that reveal community preferences, and helps you determine which approach best suits your web development workflow.
The Four Main Approaches to CSS Property Ordering
Over years of community discussion and formal polling, four distinct approaches to CSS property ordering have emerged as the primary methods developers use to structure their stylesheets. Each approach reflects different priorities, from pure simplicity to logical grouping, and understanding these methods is essential for making informed decisions about your own CSS organization strategy.
Random Ordering: The "Just Get It Done" Approach
Random ordering represents the most informal approach to CSS property organization, where developers add properties in whatever order occurs to them during the writing process. This method is often a byproduct of deadline pressure, rapid prototyping, or simple habit rather than an intentional organizational strategy.
Key characteristics:
- No consistent pattern or structure
- Properties added as they're needed during development
- Often results from time pressure or quick iterations
- Requires scanning entire declaration blocks to find specific properties
Alphabetical Ordering: Consistency Through Convention
Alphabetical ordering arranges CSS properties strictly from A to Z within each declaration block, creating a predictable and easily searchable structure regardless of the properties being used. This approach gained significant traction among developers who value consistency and predictability.
Example:
.element {
align-items: center;
background-color: #fff;
border-radius: 8px;
color: #333;
display: flex;
justify-content: space-between;
}
Advantages:
- Objective, non-debatable ordering
- Matches browser developer tools display order
- Easy to learn and apply
- Scales naturally as CSS evolves
Grouped by Type: Logical Relationships First
Grouped-by-type ordering organizes CSS properties according to their functional category, placing related properties together in logical clusters. This approach reflects a semantic understanding of CSS, where properties that affect similar aspects of element rendering are grouped for conceptual clarity.
Common category groupings:
- Box model: width, height, margin, padding, border
- Layout: display, position, flexbox, grid
- Typography: font, color, line-height, text
- Visual: background, opacity, transforms, transitions
Ordering by Property Name Length
A less common approach involves ordering CSS properties by the length of their names. This method emerged from discussions about code aesthetics but has never gained widespread adoption in professional development environments.
Poll Results: What the Data Tells Us
Understanding how the developer community actually approaches CSS property ordering requires examining multiple polling efforts conducted over the years.
The CSS-Tricks 2012 Poll Findings
Chris Coyier's seminal poll on CSS-Tricks presented four ordering options to the community and generated substantial participation. The poll established the four canonical approaches that continue to frame discussions about CSS organization.
Key findings:
- No single approach commanded a majority preference
- Community emphasized consistency over specific method choice
- Debates about organization reflected legitimate arguments for each approach
The 2021 Twitter Poll: Modern Developer Preferences
Manuel Matuzovic's 2021 Twitter poll provided more recent data, showing grouped-by-type ordering as the clear leader, with alphabetical ordering as a strong second choice.
Modern preference distribution:
- Grouped by type: Most popular approach
- Alphabetical: Strong second choice
- Random ordering: Significantly trailing
- Hybrid approaches: Growing recognition
Community Discussion Themes
Across multiple polling efforts, consistent themes emerged:
-
Team consistency is paramount -- developers across all preference groups emphasized that consistency within a project or team matters more than which specific approach is chosen.
-
Automated tools are valued -- developers noted that IDE plugins and build tools can enforce ordering conventions without requiring manual attention during coding.
-
Hybrid approaches are practical -- many developers use grouped-by-type ordering while alphabetizing within groups, combining logical flow with predictable positioning.

Best Practices for Modern CSS Development
Establishing effective CSS property ordering practices requires balancing theoretical considerations with practical constraints, team dynamics, and modern development workflows.
Prioritize Team Consistency Over Personal Preference
The most important principle for CSS property ordering is establishing consistency within your project or team and adhering to that convention across all stylesheets. Whether your team chooses alphabetical ordering, grouped-by-type ordering, or another approach entirely, the benefits of predictability and reduced cognitive load outweigh any theoretical advantages of one method over another.
Implementation strategies:
- Include ordering conventions in team style guides
- Onboard new team members with explicit training on project conventions
- Use pull request reviews to reinforce consistency
- Document decisions for future reference
Leverage Automated Tools for Enforcement
Modern development workflows benefit significantly from automated tools that enforce property ordering conventions without requiring manual attention from developers.
Recommended tools:
- VS Code CSS sorting extensions
- PostCSS with postcss-sorting plugin
- Prettier with CSS support
- Build pipeline enforcement
Consider Context When Choosing Approaches
Different project contexts may warrant different ordering approaches:
- Component-based architectures: May benefit from simpler alphabetical ordering for many small, focused style blocks
- Global stylesheets: May benefit more from grouped ordering where logical structure helps navigate complex blocks
- Mixed approaches: Some teams use different approaches for different contexts with clear documentation
Our web development services follow industry best practices for CSS organization, ensuring maintainable and scalable stylesheets for projects of any size. We work with modern frameworks and methodologies that prioritize code quality and team collaboration.
Performance Considerations
A common question concerns whether property ordering affects rendering performance.
Rendering Independence
CSS declarations are processed as atomic units by browser rendering engines, with each property's cascade and inheritance computed independently of its position within the declaration block. Whether color appears first or last in a rule, the browser applies it identically.
Key insight: Property ordering within a declaration block has no meaningful impact on browser rendering performance.
Build-time Optimization
While runtime performance is unaffected, build-time processing can be optimized through consistent ordering. Minifiers and build tools can more effectively process and optimize CSS when properties appear in consistent patterns.

Frequently Asked Questions
Does CSS property ordering affect page performance?
No, property ordering within a declaration block has no meaningful impact on browser rendering performance. CSS declarations are processed independently of their position. Focus on meaningful optimizations like selector efficiency instead.
Should I use alphabetical or grouped ordering?
Choose the approach your team can consistently maintain. Grouped ordering offers logical structure, while alphabetical provides predictability. Both are valid when applied consistently throughout your codebase.
How do I enforce ordering in my build process?
Use PostCSS with the postcss-sorting plugin, Prettier's CSS formatting, or Stylelint with ordering rules configured. These tools can automatically fix ordering issues during builds or in CI/CD pipelines.
Can I use different ordering for different files?
While technically possible, mixing approaches in a project creates inconsistency. Choose one approach and apply it uniformly. If context truly warrants different approaches, document this clearly and ensure team alignment.
Conclusion: Finding Your Approach
The debate over CSS property ordering reflects the diversity of developer preferences, team contexts, and project requirements in the web development community. Poll results consistently show that no single approach dominates, with grouped-by-type and alphabetical ordering emerging as the most popular methods.
For developers and teams establishing their approach, the most important decision is choosing a consistent method and applying it uniformly. Whatever approach you choose, approach it intentionally, apply it consistently, and trust that the developer who inherits your code will appreciate the clarity and predictability your conventions provide.
The poll results remind us that even seemingly trivial decisions about code organization matter to developers, reflecting our broader commitment to writing maintainable, professional-quality stylesheets. By following proven CSS development practices, teams can create stylesheets that are both efficient and easy to maintain.
