By specifying grayscale value to the filter property of CSS we can create a black and white image. filter property can be used to apply special effects like blur, drop-shadow to images.
Syntax
The syntax of CSS filter property is as follows −
Selector { filter: grayscale(100%); -webkit-filter: grayscale(100%); }
Example
The following examples illustrate CSS filter property.
<!DOCTYPE html> <html> <head> <style> img { margin: 2%; border-radius: 25%; } img:nth-of-type(even) { filter: grayscale(100%); -webkit-filter: grayscale(100%); } </style> </head> <body> <img src="https://images.unsplash.com/photo-1611825715408-826f2b19c43f?crop=entropy&cs=tinysrgb&fit=crop&fm=jpg&h=200&ixlib=rb-1.2.1&q=80&w=200" alt="img from unsplash"> <img src="https://images.unsplash.com/photo-1611825715408-826f2b19c43f?crop=entropy&cs=tinysrgb&fit=crop&fm=jpg&h=200&ixlib=rb-1.2.1&q=80&w=200" alt="img from unsplash"> </body> </html>
This gives the following output
Example
<!DOCTYPE html> <html> <head> <style> img { margin: 2%; } img:nth-of-type(odd) { filter: grayscale(100%); -webkit-filter: grayscale(100%); } </style> </head> <body> <img src="https://images.unsplash.com/photo-1611781750917-8777ab68668a?crop=entropy&cs=tinysrgb&fit=crop&fm=jpg&h=256&ixlib=rb-1.2.1&q=80&w=256"> <img src="https://images.unsplash.com/photo-1611781750917-8777ab68668a?crop=entropy&cs=tinysrgb&fit=crop&fm=jpg&h=256&ixlib=rb-1.2.1&q=80&w=256"> </body> </html>
