I am writing this post after I struggled today to find a way to implement a simple and responsive image slider for my product page (ecommerce mern app).


## HTML

```html
<!DOCTYPE html>
<html lang="en">
    <head>
        <meta charset="UTF-8" />
        <meta name="viewport" content="width=device-width" />
        <link rel="stylesheet" href="style.css" type="text/css" media="all" />
        <title>product page</title>
    </head>
    <body>
        <div class="product">
            <div class="product__images">
                <img
                    src="https://res.cloudinary.com/dard8s66g/image/upload/v1647993803/ecommerce/smartphone/623a63c9251afc7d338faab5/vzjovup3izma7q2skzcf.jpg"
                    alt="google pixel 6"
                    class="product__main-image"
                    id="main-image"
                />

                <div class="product__slider-wrap">
                    <div class="product__slider">
                        <img
                            src="https://res.cloudinary.com/dard8s66g/image/upload/v1647993803/ecommerce/smartphone/623a63c9251afc7d338faab5/vzjovup3izma7q2skzcf.jpg"
                            alt="google pixel 6"
                            class="product__image product__image--active"
                        />
                        <img
                            src="https://res.cloudinary.com/dard8s66g/image/upload/v1647993806/ecommerce/smartphone/623a63c9251afc7d338faab5/xtfslzmfpwg3bwoyylve.jpg"
                            alt="google pixel 6"
                            class="product__image"
                        />
                        <img
                            src="https://res.cloudinary.com/dard8s66g/image/upload/v1647993811/ecommerce/smartphone/623a63c9251afc7d338faab5/kqp1ffmcfs2q6ctck36i.jpg"
                            alt="google pixel 6"
                            class="product__image"
                        />
                        <img
                            src="https://res.cloudinary.com/dard8s66g/image/upload/v1647993808/ecommerce/smartphone/623a63c9251afc7d338faab5/fkco14duxzv8rnkyctbr.jpg"
                            alt="google pixel 6"
                            class="product__image"
                        />
                    </div>
                </div>
            </div>
        </div>
        <script src="main.js"></script>
    </body>
</html>

```
## CSS

```css
* {
  padding: 0;
  margin: 0;
  box-sizing: border-box;
}

body {
  font-family: sans-serif;
}

.product {
  width: 100%;
  height: 100vh;
}

.product__images {
  width: 100%;
  height: 100%;
  display: flex;
  flex-direction: column;
  justify-content: center;
  align-items: center;
}

.product__main-image {
  max-width: 500px;
  max-height: 600px;
  object-fit: cover;
  cursor: pointer;
  border: 1px solid #070707;
}

.product__slider-wrap {
  max-width: 500px;
  min-height: 100px;
  display: flex;
  align-items: center;
}

.product__slider {
  width: 100%;
  display: flex;
  flex-wrap: nowrap;
  overflow-x: auto;
}

.product__image {
  max-width: 180px;
  max-height: 100px;
  object-fit: cover;
  cursor: pointer;
  opacity: 0.5;
  margin: 0.25rem;
  border: 1px solid #070707;
}

.product__image:first-child {
  margin-left: 0;
}

.product__image:last-child {
  margin-right: 0;
}

.product__image:hover {
  opacity: 1;
}

.product__image--active {
  opacity: 1;
}

.product__slider::-webkit-scrollbar {
  height: 10px;
}

.product__slider::-webkit-scrollbar-thumb {
  background-color: #f9564f;
  border-radius: 50px;
}

```

## JavaScript

```js
const mainImage = document.getElementById("main-image");
const images = document.querySelectorAll(".product__image");

images.forEach((image) => {
    image.addEventListener("click", (event) => {
        mainImage.src = event.target.src;

        document
            .querySelector(".product__image--active")
            .classList.remove("product__image--active");

        event.target.classList.add("product__image--active");
    });
});

```

## Conclusion

And there you have it. I hope this post was useful to at least one person who does not want to use third-party code or follow a lengthy tutorial to create a fancy slider.

This is my first post and I'm still new to web development, so any constructive criticism is welcome.

Have a good day (or night, if you are a night owl like me).
