html 5 and css code for make a shop website

                                           
                         This HTML5 code is a simple template for a store site:

<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <title>فروشگاه آنلاین</title> <link rel="stylesheet" href="styles.css"> </head> <body> <header> <div class="container"> <h1>فروشگاه آنلاین من</h1> </div> </header> <nav> <ul> <li><a href="#">خانه</a></li> <li><a href="#">محصولات</a></li> <li><a href="#">درباره ما</a></li> <li><a href="#">تماس با ما</a></li> </ul> </nav>
<section class="products"> <div class="container"> <div class="product"> <img src="product1.jpg" alt=""> <h2>product name</h2> <p> Price: 99,000 Tomans</p> <a href="#" class="btn">Add to cart</a> </div> <!-- Other products --> </div> </section>
<footer> <p>Designed by me | All rights reserved</p> </footer> </body> </html>
This is just a basic template and it needs more codes in the products, shopping cart, payment, etc sections to turn it into a full store. But this will be a good starting point for you. 

This CSS code gives a modern style to that HTML template:

*{
box-sizing: border-box;
}

body {
font-family: "Poppins", sans-serif;
}

header {
background: #333;
color: #fff;
padding: 1rem;
}

.container {
max-width: 1200px;
margin: 0 auto;
text-align: center;
}

nav {
background: #ddd;
padding: 1rem 0;
}

nav ul {
list-style: none;
display: flex;
justify-content: center;
}

nav li a {
color: #333;
text-decoration: none;
padding: 1rem 2rem;
}

.products .product {
border: 1px solid #ddd;
padding: 1rem;
margin-bottom: 2rem;
}

.products img {
width: 100px;
}

.products h2 {
margin: 0 0 0.5rem 0;
}

.products .btn {
background: #333;
color: #fff;
padding: 0.5rem 1rem;
text-decoration: none;
}

footer {
background: #333;
color: #fff;
text-align: center;
padding: 1rem;
}

@media (min-width: 700px) {
.products .product {
display: flex;
align-items: center;
}

.products img {
width: 200px;
margin-right: 1rem;
}
}

This CSS code includes a simple grid layout, modern font, attractive colors and responsive measurements that will make your online store look attractive and modern.

If you need more changes, you can edit the CSS to give your site a completely individual look.
