CSS filter property
Description
CSS filter property applies filter to an element. There are many functions that we can use to filter an element differently.
Syntax
filter : none | blur() | brightness() | contrast() | drop-shadow() | grayscale() | hue-rotate() | invert() | opacity() | sepia()
Property values
noneDefault
-
No filter is applied to the element.
filter: none;
blur(+ve length)
-
It applies blur to an element.
It accepts only length value and not percentage value.
filter: blur(10px);
brightness(+ve-length or +ve-percentage)
-
It determines the brightness of an element. 100% or 1 value does not affect the element while other values within the range (0-1 or 0%-100%) show an effect.
filter: brightness(50%);
contrast(+ve-length or +ve-percentage)
-
It defines the contrast behavior of content. 100% value does not affect while the other values within the range (0-1 or 0%-100%) show a contrast behavior. 0% values show fully grayscale.
filter: contrast(50%);
drop-shadow(X-offset Y-offset blur-radius color)
-
It applies drop-shadow to the box (element). The parameter consists of horizontal-offset, vertical-offset, blur-radius, and color of the shadow.
filter: drop-shadow(5px 5px 5px rgba(230,230,230,1));
grayscale(+ve-length or +ve-percentage)
-
It converts an element into grayscale. 100% value means full grayscale.
filter: grayscale(50%);
hue-rotate(angle)
-
It represents huge rotation on the element. Actually, the parameter defines the number of degrees around the color circle to which the samle colors will be adjusted.
filter: hue-rotate(30deg);
invert(+ve-length or +ve-percentage)
-
It completely inverts the sample of the element. The argument value defines the proportion of conversion. 0% does not affect the element. While 100% completely inverts the element.
filter: invert(50%);
opacity(+ve-length or +ve-percentage)
-
It represents transparency of the object (element). 0% or 0 is fully opaque. And 100% or 1 is fully transparent.
filter: opacity(60%);
sepia(+ve-length or +ve-percentage)
-
converts an input element or image to sepia. Values vary between 0% (0) and 100% (1).
filter: sepia(30%);
