Here is the code with the HTML and CSS formatted for readability:
**HTML:**
```html
<div class="product-card">
<!-- product images -->
<img src="image1.jpg" alt="Product Image 1">
<img src="image2.jpg" alt="Product Image 2">
<!-- product details -->
<h2>Product Name</h2>
<p>Description of the product</p>
<ul>
<li>Feature 1</li>
<li>Feature 2</li>
<li>Feature 3</li>
</ul>
<!-- pricing and promotions -->
<p>Pricing:</p>
<p>$X.XX</p>
<p> promotion: Buy one get one free</p>
</div>
<div class="product-card">
<!-- product images -->
<img src="image3.jpg" alt="Product Image 1">
<img src="image4.jpg" alt="Product Image 2">
<!-- product details -->
<h2>Product Name</h2>
<p>Description of the product</p>
<ul>
<li>Feature 1</li>
<li>Feature 2</li>
<li>Feature 3</li>
</ul>
<!-- pricing and promotions -->
<p>Pricing:</p>
<p>$X.XX</p>
<p> promotion: Buy one get one free</p>
</div>
<!-- more products -->
```
**CSS:**
```css
.product-card {
width: 300px;
margin: 20px;
}
.product-image {
display: block;
width: 100%;
height: 150px;
object-fit: cover;
}
.product-title {
font-size: 18px;
margin-bottom: 10px;
}
.product-description {
font-size: 14px;
color: #666;
margin-bottom: 20px;
}
.product-features {
list-style: none;
padding: 0;
margin: 0;
}
.product-features li {
font-size: 12px;
margin-bottom: 5px;
}
.product-pricing {
font-size: 18px;
color: #333;
}
.product-promotion {
font-size: 14px;
color: #999;
}
```
**JavaScript:**
```javascript
// JavaScript code goes here
```
Note that I've removed the unnecessary HTML and CSS elements, and reorganized the structure to make it more readable. I've also added comments to explain what each section of the code is doing. Let me know if you have any questions or need further clarification!
