CSS Filter Property
There is a CSS property filter
which allows you to manipulate properties of an element such as their blur, brightness, contrast, grayscale, opacity, and more. This is most often applied to images, but does work on any element.
.single-filter {
filter: opacity(50%);
}
.multiple-filters {
filter: blur(5px) grayscale(100%);
}
Here comes our friendly neighborhood Pikachu to help show us what this looks like:
Here is a good reference for what filter
can do.
