Rounded Black and White Image Effect using CSS

In web applications, you might not have control of user-uploaded content such as images. Moreover, creating a beautiful web design, a rich user interface, and great experience requires taking full advantage of CSS.

A great example of custom-styled images is on most social media applications such as Facebook, Twitter, and Linkedin, where profile pictures are displayed in a circle.

This article shows you how you can create a similar effect to display a black and white image with rounded corners.

This is the markup for the image in HTML:

 <img
     src="profile.jpg"
     width="200"
     height="200"
     alt="Profile picture"
     class="rounded grayscale"
 />

The img tag is styled using two CSS utility classes rounded and grayscale.

The rounded class turns the square image into a circle by using the border-radius property and setting it to 50% of the image's width.

.rounded {
  border-radius: 50%;
}

Sara Cope explores the wonderful border-radius property in depth on CSS Tricks.

The grayscale class creates the black and white effect. You need to use the filter property with the grayscale option and specify 100% which completely saturates the color. According to MDN Web Docs most modern browsers support filter property with the -webkit- vendor prefix.

.grayscale {
  filter: grayscale(100%);
  -webkit-filter: grayscale(100%);
}

To sum up, you can use the border-radius and filter with grayscale properties to stylize an image with rounded corners and a black and white appearance. This is especially useful when you don't have control over the image content. Thanks for reading and I hope you found this interesting!
