Introduction

Do you want to learn how to center a div using CSS? Centering elements on a web page is a common design feature, and mastering the technique can help you create a professional-looking website. In this blog post, we’ll discuss how to center a div using the margin and transform properties.

Margin Property

The margin property is the most common way to center a div. You can use the auto value for the left and right margins to make the div center itself. Here is an example of the margin property in action:

div {
    margin-left: auto;
    margin-right: auto;
}

Transform Property

The transform property is a newer way to center a div. It works by translating the div to the center of the page. Here is an example of the transform property in action:

div {
    position: absolute;
    top: 50%;
    left: 50%;
    transform: translate(-50%, -50%);
}

Flexbox

Flexbox is another way to center a div. It is a powerful tool that allows you to align and order elements on a page. To center a div using flexbox, you can use the justify-content and align-items properties. Here is an example of flexbox in action:

div {
    display: flex;
    justify-content: center;
    align-items: center;
}

Conclusion

Centering a div is a common design feature, and there are several ways to do it. The most common way is to use the margin property, but the transform and flexbox properties can also be used. With some practice, you can master the technique and create a professional-looking website.

For basic styles adding bootstrap UI cdn.

And for DOM manipulation, adding jquery cdn in the header of html document.

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.slim.min.js"></script>

Adding main image

Adding some high quality image from google search results.

  <div class="header" id="parallex">
    <img class="header-image" src="https://handluggageonly.co.uk/wp-content/uploads/2015/12/London-1.jpg" alt="">
  </div>

Adding some random content

Adding some lorem ipsum content to make the page looks longer. So that we can scroll and see the effect.

<p class="container">Lorem ipsum dolor sit amet, consectetur adipisicing elit. Recusandae similique perferendis quaerat porro, facilis quidem itaque qui excepturi autem ab iure ea quae vero dolorum fugiat alias accusantium, unde laborum facere pariatur soluta quibusdam

So far we have added the HTML content. Lets add some CSS magic.

CSS magic

body: {
  height: 100vh;
  width: 100vw;
  overflow: hidden;
}

img {
  width: 100%;
}

.header {
  height: 500px;
  overflow: hidden;
}

p {
  font-family: tahoma;
  font-size: 20px;
  padding: 50px;
}

Basically, this CSS sets the document height and width, and keeping the image stretch to 100%.

So far we have added some HTML text content and image in header. To add some scroll and zoom effect, lets add some javascript/jQuery code.

jQuery code

$(window).scroll(function() {
  var scroll = $(window).scrollTop();
  console.log(scroll);
  $("#parallex img").css({
    width: 100 + scroll / 5 + "%"
  });
});

The above code, adds the width of image based on the windows scroll position.

Final Output

You can checkout the final output in the below codepen.
