Styled Components

Overview

styled-components enables CSS-in-JS with tagged template literals. Components are styled directly in JavaScript with access to props, themes, and dynamic values. Supports SSR and tree-shaking.

Capabilities

• Tagged template literal syntax for styling
• Dynamic styles via props
• ThemeProvider for global theming
• Server-side rendering with ServerStyleSheet
• Keyframe animations
• Extending and composing components
• Transient props ($prefix) to avoid DOM forwarding

When to Use

Trigger phrases:

• "styled components"

• "styled-components CSS-in-JS — tagged templates, theming, props, animations, SSR,"

• React projects needing scoped, dynamic CSS

• Component libraries with prop-driven styles

• Server-side rendered React apps (Next.js)

• Theming with runtime color/mode switching

When NOT to Use

• Task is about content strategy, not creation (use strategy skills)
• Task is about content distribution (use distribution skills)
• You need to analyze content performance (use analytics skills)
• Task is about content moderation (use moderation tools)
• You don't have content guidelines
• Task requires domain expertise (consult experts)

Pseudo Code

The styled-components workflow follows a standard pipeline pattern.

Core flow:

# styled-components primary flow
input = prepare(raw_data)
result = process(input, config={animations, components, performance, props, styled})
validate(result)
deliver(result)

Error handling:

on error:
  log(error_details)
  retry_with_backoff(max=3)
  if still_failing: alert_and_escalate()

Basic Usage

import styled from "styled-components"

const Button = styled.button`
  background: ${(props) => props.$primary ? "#3b82f6" : "#e5e7eb"};
  color: ${(props) => props.$primary ? "white" : "#374151"};
  padding: 8px 16px;
  border-radius: 6px;
  border: none;
  cursor: pointer;
  &:hover { opacity: 0.9; }
`

// Usage: <Button $primary>Click</Button>

Theme Provider

import { ThemeProvider } from "styled-components"

const theme = {
  colors: {
    primary: "#3b82f6",
    background: "#ffffff",
    text: "#1f2937",
  },
  spacing: { sm: "8px", md: "16px", lg: "24px" },
}

function App() {
  return (
    <ThemeProvider theme={theme}>
      <MyApp />
    </ThemeProvider>
  )
}

Theme Access

const Card = styled.div`
  background: ${({ theme }) => theme.colors.background};
  padding: ${({ theme }) => theme.spacing.md};
  color: ${({ theme }) => theme.colors.text};
`

Extending Components

const PrimaryButton = styled(Button)`
  background: #3b82f6;
  color: white;
  font-weight: 600;
`

Keyframes

import { keyframes } from "styled-components"

const fadeIn = keyframes`
  from { opacity: 0; transform: translateY(10px); }
  to { opacity: 1; transform: translateY(0); }
`

const AnimatedDiv = styled.div`
  animation: ${fadeIn} 0.3s ease-out;
`

Common Patterns

• Transient props: Use $ prefix ($primary, $size) to prevent DOM forwarding
• attrs: styled.input.attrs({ type: "text" }) for default attributes
• Global styles: createGlobalStyle for CSS reset and global rules
• Composition: const StyledLink = styled(Link) for React Router links
• Performance: Use .attrs() for static values, memoize expensive computations

How to Use

1. Define content goal (traffic, engagement, conversion, brand awareness)
2. Research target audience pain points and search intent
3. Generate content using appropriate AI tools
4. Edit and humanize output for authenticity
5. Optimize for target platform (SEO, hashtags, format)
6. Schedule and distribute across channels
7. Measure performance and iterate

Red Flags

• AI-generated content sounds robotic: Always run through humanizer before publishing
• Engagement dropping week-over-week: Content fatigue or algorithm change — vary formats
• Duplicate content across platforms: Adapt content per platform, don't just cross-post
• No content calendar: Sporadic posting kills audience retention
• Ignoring analytics: Content without measurement is just publishing, not marketing

Verification

• Skill output matches expected behavior

Process

1. Analyze the task requirements
2. Apply domain expertise
3. Verify output quality
