                    <div class="trend-content">
                        <h3>The Workhorse of Customization</h3>
                        <p>Screen printing involves creating a stencil (or "screen") and pushing ink through it onto the cotton fabric. Each color in your design requires a separate screen, making it ideal for designs with a limited number of solid colors.</p>
                        <ul>
                            <li><strong>Best For:</strong> Simple logos, text, and bold graphics with 1-4 solid colors.</li>
                            <li><strong>Key Advantage:</strong> Extremely cost-effective for large quantity orders (1,000+ pieces).</li>
                            <li><strong>The Result:</strong> A thick, vibrant, and highly durable print that sits on top of the fabric.</li>
                        </ul>
                    </div>

                    <div class="trend-content">
                        <h3>The Artist's Choice</h3>
                        <p>Direct-to-Garment (DTG) printing works like a standard inkjet printer, applying water-based inks directly onto the cotton. This allows for an unlimited number of colors and incredible detail, as the ink is absorbed by the fabric fibers.</p>
                         <ul>
                             <li><strong>Best For:</strong> Photorealistic images, complex illustrations, gradients, and intricate, multi-color designs.</li>
                             <li><strong>Key Advantage:</strong> No setup fees per color, making it great for smaller runs with complex art.</li>
                             <li><strong>The Result:</strong> A soft, breathable print that is integrated into the fabric, with no raised texture.</li>
                         </ul>
                    </div>

                <h2 id="heat-transfer">Heat Transfer: For Versatility & Vibrancy</h2>
                <div class="technique-feature">
                    <div class="trend-content">
                        <h3>The Versatile Solution</h3>
                        <p>This method involves printing your design onto a special transfer paper, which is then applied to the cotton bag using heat and pressure. It's a highly versatile technique that combines the vibrancy of DTG with some of the durability of screen printing.</p>
                         <ul>
                             <li><strong>Best For:</strong> Designs that need to be exceptionally vibrant, especially on dark-colored bags.</li>
                             <li><strong>Key Advantage:</strong> Excellent color saturation and the ability to reproduce fine details consistently across a large batch.</li>
                             <li><strong>The Result:</strong> A smooth, slightly glossy finish that sits on top of the fabric.</li>
                         </ul>
