Human Made CSS/SCSS Standards

Naming Conventions

Use BEM-like naming:

• Block: .user-card
• Element: .user-card__title
• Modifier: .user-card--featured

Copy.user-card {
    padding: 1rem;

    &__title {
        font-size: 1.25rem;
    }

    &__content {
        margin-top: 0.5rem;
    }

    &--featured {
        border: 2px solid var(--wp--preset--color--primary);
    }
}

CSS Custom Properties

• Use CSS custom properties via theme.json tokens where possible
• Reference WordPress preset values: var(--wp--preset--color--primary)
• Define component-specific properties at the component level

Copy.component {
    --component-spacing: 1rem;
    padding: var(--component-spacing);
}

theme.json Integration

For WordPress themes, prefer theme.json for:

• Color palettes
• Typography scales
• Spacing presets
• Layout settings

Reference in CSS:

Copy.element {
    color: var(--wp--preset--color--contrast);
    font-size: var(--wp--preset--font-size--medium);
    padding: var(--wp--preset--spacing--40);
}

SCSS Guidelines

• Use nesting sparingly (max 3 levels deep)
• Extract repeated values into variables
• Use mixins for repeated patterns
• Prefer @use over @import for module loading

Class Naming

• Use kebab-case: .my-component-name
• Avoid IDs for styling
• Avoid overly generic names: prefer .article-card over .card
• Prefix utility classes if used: .u-visually-hidden

Linting

Projects use Stylelint:

• Config file: .stylelintrc.js or .stylelintrc.json
• Run with: npm run lint:css or npx stylelint "**/*.scss"
