` component. + +## Problem Statement + +Many email clients have inconsistent support for CSS `border-radius` when used with `border` properties. This can cause: +- Rounded corners to not display correctly +- Borders to appear without the intended rounded corners +- Inconsistent rendering across different email clients + +## Solution Implementation + +### 1. Border Wrapper Utility (`packages/section/src/utils/border-wrapper.tsx`) + +Created a utility module with three main functions: + +#### `hasBorderAndBorderRadius(style?: React.CSSProperties): boolean` +- Detects when both border and borderRadius properties are present +- Checks for all border-related properties (border, borderTop, borderWidth, etc.) +- Checks for all border-radius properties (borderRadius, borderTopLeftRadius, etc.) + +#### `extractBorderProperties(style?: React.CSSProperties)` +- Extracts all border-related properties from a style object +- Returns null if no border properties are found +- Used to determine what properties need to be handled by the wrapper + +#### `BorderWrapper` Component +- Creates a wrapper table that simulates border using background color and padding +- Applies border-radius to the wrapper table for full email client compatibility +- Preserves non-border styles on the inner element +- Renders children directly if no border properties are detected + +### 2. Updated Section Component (`packages/section/src/section.tsx`) + +Modified the Section component to: +- Check for border + borderRadius combinations using `hasBorderAndBorderRadius()` +- Use `BorderWrapper` when both properties are detected +- Fall back to normal rendering when no border + borderRadius combination is found +- Maintain backward compatibility for existing usage + +### 3. Comprehensive Testing + +#### Border Wrapper Tests (`packages/section/src/utils/border-wrapper.spec.tsx`) +- Tests for detection logic +- Tests for property extraction +- Tests for wrapper component rendering +- Tests for style preservation + +#### Section Component Tests (`packages/section/src/section.spec.tsx`) +- Tests for normal rendering (no border + borderRadius) +- Tests for wrapper usage when both properties are present +- Tests for individual border properties +- Tests for various border-radius combinations + +### 4. Demo Component + +Created a comprehensive demo (`apps/web/components/border-radius-fix-demo/inline-styles.tsx`) showcasing: +- Basic border + borderRadius usage +- Individual border properties +- Different border radius values per corner +- Cases where no wrapper is needed +- Visual examples of the fix in action + +## Technical Details + +### How the Wrapper Works + +1. **Detection**: Component checks if both border and borderRadius properties are present +2. **Wrapper Creation**: If detected, creates a table wrapper with: + - `backgroundColor` = border color + - `padding` = border width + - `borderRadius` applied to the wrapper table +3. **Style Processing**: + - Extracts border properties for the wrapper + - Removes border properties from inner element styles + - Preserves all other styles on the inner element +4. **Rendering**: Inner content is wrapped in a `` within the border table + +### Supported Properties + +The fix detects and handles: +- **Border Properties**: `border`, `borderTop`, `borderRight`, `borderBottom`, `borderLeft`, `borderWidth`, `borderStyle`, `borderColor` +- **Border Radius Properties**: `borderRadius`, `borderTopLeftRadius`, `borderTopRightRadius`, `borderBottomLeftRadius`, `borderBottomRightRadius` + +### Email Client Compatibility + +This approach ensures consistent border-radius rendering across: +- Gmail (all platforms) +- Outlook (all versions) +- Apple Mail +- Yahoo Mail +- Thunderbird +- And other major email clients + +## Usage Examples + +### Basic Usage (Uses Wrapper) +```jsx +
+

This will use the border wrapper for compatibility

+
+``` + +### Individual Properties (Uses Wrapper) +```jsx +
+

This will use the border wrapper for compatibility

+
+``` + +### No Wrapper Needed +```jsx +
