+## styled-components / Emotion
+
+### Style Fixes
+
+```jsx
+// Before
+const Container = styled.div`
+ width: 100%;
+`;
+
+// After
+const Container = styled.div`
+ width: 100%;
+ max-width: 100%;
+ overflow-x: hidden;
+
+ @media (max-width: 768px) {
+ padding: 1rem;
+ }
+`;
+```
+
+### Responsive Support
+
+```jsx
+const Card = styled.div`
+ display: grid;
+ grid-template-columns: repeat(3, 1fr);
+ gap: 1.5rem;
+
+ @media (max-width: 1024px) {
+ grid-template-columns: repeat(2, 1fr);
+ }
+
+ @media (max-width: 640px) {
+ grid-template-columns: 1fr;
+ gap: 1rem;
+ }
+`;
+```
+
+### Consistency with Theme
+
+```jsx
+// theme.js
+export const theme = {
+ colors: {
+ primary: '#2563eb',
+ text: '#1f2937',
+ textLight: '#4b5563', // Improved contrast
+ },
+ spacing: {
+ sm: '0.5rem',
+ md: '1rem',
+ lg: '1.5rem',
+ },
+};
+
+// Usage
+const Text = styled.p`
+ color: ${({ theme }) => theme.colors.text};
+ margin-bottom: ${({ theme }) => theme.spacing.md};
+`;
+```

+
+## Vue (Scoped Styles)
+
+### Fixing Scoped Styles
+
+```vue
+
+
+
+
+
+```
+
+### Deep Selectors (Affecting Child Components)
+
+```vue
+
+```
+
+---
+
+## Next.js / App Router
+
+### Global Style Fixes
+
+```css
+/* app/globals.css */
+:root {
+ --foreground: #171717;
+ --background: #ffffff;
+}
+
+/* Prevent layout overflow */
+html, body {
+ max-width: 100vw;
+ overflow-x: hidden;
+}
+
+/* Prevent image overflow */
+img {
+ max-width: 100%;
+ height: auto;
+}
+```
+
+### Fixes in Layout Components
+
+```tsx
+// app/layout.tsx
+export default function RootLayout({ children }) {
+ return (
+
+
+
+
+ {children}
+
+
+
+
+ );
+}
+```
+
+---
+
+## Common Patterns
+
+### Fixing Flexbox Layout Issues
+
+```css
+/* Before: Items overflow */
+.flex-container {
+ display: flex;
+ gap: 1rem;
+}
+
+/* After: Wrap and size control */
+.flex-container {
+ display: flex;
+ flex-wrap: wrap;
+ gap: 1rem;
+}
+
+.flex-item {
+ flex: 1 1 300px; /* grow, shrink, basis */
+ min-width: 0; /* Prevent flexbox overflow issues */
+}
+```
+
+### Fixing Grid Layout Issues
+
+```css
+/* Before: Fixed column count */
+.grid-container {
+ display: grid;
+ grid-template-columns: repeat(4, 1fr);
+}
+
+/* After: Auto-adjust */
+.grid-container {
+ display: grid;
+ grid-template-columns: repeat(auto-fit, minmax(250px, 1fr));
+ gap: 1.5rem;
+}
+```
+
+### Organizing z-index
+
+```css
+/* Systematize z-index */
+:root {
+ --z-dropdown: 100;
+ --z-sticky: 200;
+ --z-modal-backdrop: 300;
+ --z-modal: 400;
+ --z-tooltip: 500;
+}
+
+.modal {
+ z-index: var(--z-modal);
+}
+```
+
+### Adding Focus States
+
+```css
+/* Add focus state to all interactive elements */
+button:focus-visible,
+a:focus-visible,
+input:focus-visible,
+select:focus-visible,
+textarea:focus-visible {
+ outline: 2px solid #2563eb;
+ outline-offset: 2px;
+}
+
+/* Customize focus ring */
+.custom-focus:focus-visible {
+ outline: none;
+ box-shadow: 0 0 0 3px rgba(37, 99, 235, 0.5);
+}
+```
+
+---
+
+## Debugging Techniques
+
+### Visualizing Element Boundaries
+
+```css
+/* Use only during development */
+* {
+ outline: 1px solid red !important;
+}
+```
+
+### Detecting Overflow
+
+```javascript
+// Run in console to detect overflow elements
+document.querySelectorAll('*').forEach(el => {
+ if (el.scrollWidth > el.clientWidth) {
+ console.log('Horizontal overflow:', el);
+ }
+ if (el.scrollHeight > el.clientHeight) {
+ console.log('Vertical overflow:', el);
+ }
+});
+```
+
+### Checking Contrast Ratio
+
+```javascript
+// Use Chrome DevTools Lighthouse or axe DevTools
+// Or check at the following site:
+// https://webaim.org/resources/contrastchecker/
+```
