- Living style guides keep designers and developers in sync, especially with complex elements and patterns.
- They’re important to remove inconsistencies and unneeded complexities when build a large site or collection of sites, e.g. lots of unneeded color shades.
- In the study, a selection of primary and accent colors were chosen and designers could lighten and darken them by set percentages. This was meant to unify brand colors consistently.
- However, lightened or darkened colors weren’t generated automatically for some elements since it didn’t guarantee contrast or aesthetics.
- The style guide used Brad Frost’s Atomic Design methodology for building elements, but renamed the category names so people using the style guide could more easily navigate it.
- Preprocessor variables and functions were also documented in a “Helpers” category.
- They decided on a set of rules to determine how patterns are classified:
- Elements (atoms) were elements tag name selectors or single classes on one element
- Modules (molecules) were patterns that needed more than one HTML element
- Components (organisms) were patterns that could also be an HTML5 sectioning element, such as <header>, <footer>, or <article>.
- Names were hard to decide on, but once they were chosen they stuck.
- CSS was written with the BEM naming convention.
Mistakes to Avoid
- Don’t release too early. Take the time to look at every page and run needed tests.
- Be careful of CSS-Breaking Changes. These were any change that would require a class-name change, which would effect all working instances of it.
- Organize your Style Guide based on what works for your team. Organizing the elements based on Atomic Design principles confused the team in the study. Go with what makes elements easier to find.
Desirable Style Guide functions
- Completely control the structure and template.
- If not this, then at least output a JSON object for making a custom template.
- Separate code output and example output.
- Create a sortable section hierarchy.
- Parse comments in Markdown.
- Put examples in the comments, if desired.
- If generated from custom tags, define custom tags for certain elements like colors.
- If not this, then parse any key/value pair.
The group behind the study created LivingCSS as a style guide generator that met all these requirements.
