+st.markdown("""
+<div class="section">
+    <p><strong>Image Classification</strong> is a computer vision task where an algorithm is trained to recognize and classify objects within images. This process involves assigning a label or category to an image based on its visual content.</p>
+    <h2>How It Works</h2>
+    <p>Image classification typically involves the following steps:</p>
+    <ul>
+        <li><strong>Data Collection</strong>: Gather a dataset of labeled images.</li>
+        <li><strong>Preprocessing</strong>: Normalize and resize images to prepare them for the model.</li>
+        <li><strong>Model Training</strong>: Use a machine learning model, such as Swin, to learn patterns and features from the images.</li>
+        <li><strong>Inference</strong>: Apply the trained model to new images to predict their labels.</li>
+    </ul>
+    <h2>Why Use Image Classification?</h2>
+    <p>Image classification can automate and streamline many tasks, such as:</p>
+    <ul>
+        <li>Identifying objects in photos for content tagging.</li>
+        <li>Enhancing search functionality by categorizing images.</li>
+        <li>Supporting autonomous systems like self-driving cars.</li>
+    </ul>
+    <h2>Where to Use It</h2>
+    <p>Applications of image classification span across various industries:</p>
+    <ul>
+        <li><strong>Healthcare</strong>: Diagnosing diseases from medical images.</li>
+        <li><strong>Retail</strong>: Sorting and tagging product images.</li>
+        <li><strong>Security</strong>: Facial recognition for authentication.</li>
+    </ul>
+    <h2>Importance</h2>
+    <p>Image classification is crucial because it enables machines to interpret visual data, which is essential for creating intelligent systems capable of understanding and interacting with the world in a more human-like manner.</p>
+    <p>The <strong>Swin Transformer</strong> model used in this example is a state-of-the-art approach for image classification, offering advanced performance and scalability. It utilizes a hierarchical transformer architecture to capture intricate patterns and relationships within images, enhancing classification accuracy and efficiency.</p>
