Code Example: Responsive Email Grid System

// Responsive email grid component
class EmailGrid {
  constructor(columns = 2, gap = 20) {
    this.columns = columns;
    this.gap = gap;
  }

  // Generate responsive table HTML
  generateGrid(items) {
    const columnWidth = Math.floor(100 / this.columns);
    
    let html = `
      <table width="100%" cellpadding="0" cellspacing="${this.gap}" border="0">
        <tr>`;
    
    items.forEach((item, index) => {
      if (index % this.columns === 0 && index !== 0) {
        html += `</tr><tr>`;
      }
      
      html += `
        <td width="${columnWidth}%" valign="top" class="email-column">
          <table width="100%" cellpadding="0" cellspacing="0" border="0">
            <tr>
              <td style="padding: 20px; background: #f8f9fa;">
                ${item.content}
              </td>
            </tr>
          </table>
        </td>
      `;
    });
    
    // Fill empty cells if needed
    const remainingCells = this.columns - (items.length % this.columns);
    if (remainingCells < this.columns) {
      for (let i = 0; i < remainingCells; i++) {
        html += `<td width="${columnWidth}%"></td>`;
      }
    }
    
    html += `</tr></table>`;
    
    return html;
  }

  // Generate mobile CSS
  getMobileCSS() {
    return `
      @media screen and (max-width: 600px) {
        .email-column {
          display: block !important;
          width: 100% !important;
          margin-bottom: ${this.gap}px;
        }
      }
    `;
  }
}

// Usage example
const grid = new EmailGrid(3, 15);

const gridItems = [
  { content: '<h3>Feature 1</h3><p>Description here</p>' },
  { content: '<h3>Feature 2</h3><p>Description here</p>' },
  { content: '<h3>Feature 3</h3><p>Description here</p>' }
];

const gridHTML = grid.generateGrid(gridItems);
const mobileCSS = grid.getMobileCSS();

console.log('Grid HTML:', gridHTML);
console.log('Mobile CSS:', mobileCSS);
