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
