Propiedad de filtro CSS


Ejemplo

Cambie todas las imágenes a blanco y negro (100% gris):

img {
  filter: grayscale(100%);
}

Sugerencia: más ejemplos de "Pruébelo usted mismo" a continuación.


Definición y uso

La filterpropiedad define efectos visuales (como desenfoque y saturación) para un elemento (a menudo <img>).

Valor por defecto: ninguna
Heredado: No
Animable: si. Leer sobre animable
Versión: CSS3
Sintaxis de JavaScript: objeto .style.filter="escala de grises(100%)"

Compatibilidad con navegador

Los números de la tabla especifican la primera versión del navegador que es totalmente compatible con la propiedad.

Los números seguidos de -webkit- especifican la primera versión que funcionó con un prefijo.

Property
filter 53.0
18.0 -webkit-
13.0 35.0 9.1
6.0 -webkit-
40.0
15.0 -webkit-


Sintaxis CSS

filter: none | blur() | brightness() | contrast() | drop-shadow() | grayscale() | hue-rotate() | invert() | opacity() | saturate() | sepia() | url();

Sugerencia: para usar varios filtros, separe cada filtro con un espacio (consulte "Más ejemplos" a continuación).


Funciones de filtro

Nota: Los filtros que utilizan valores porcentuales (es decir, 75 %), también aceptan el valor como decimal (es decir, 0,75).

Filter Description Play it
none Default value. Specifies no effects
blur(px) Applies a blur effect to the image. A larger value will create more blur.

If no value is specified, 0 is used.
brightness(%) Adjusts the brightness of the image.

0% will make the image completely black.
100% (1) is default and represents the original image.
Values over 100% will provide brighter results.
contrast(%) Adjusts the contrast of the image.

0% will make the image completely black.
100% (1) is default, and represents the original image.
Values over 100% will provide results with more contrast.
drop-shadow(h-shadow v-shadow blur spread color) Applies a drop shadow effect to the image.

Possible values:
h-shadow - Required. Specifies a pixel value for the horizontal shadow. Negative values place the shadow to the left of the image.

v-shadow - Required. Specifies a pixel value for the vertical shadow. Negative values place the shadow above the image.

blur - Optional. This is the third value, and must be in pixels. Adds a blur effect to the shadow. A larger value will create more blur (the shadow becomes bigger and lighter). Negative values are not allowed. If no value is specified, 0 is used (the shadow's edge is sharp).

spread - Optional. This is the fourth value, and must be in pixels. Positive values will cause the shadow to expand and grow bigger, and negative values will cause the shadow to shrink. If not specified, it will be 0 (the shadow will be the same size as the element).
Note: Chrome, Safari and Opera, and maybe other browsers, do not support this 4th length; it will not render if added.

color - Optional. Adds a color to the shadow. If not specified, the color depends on the browser (often black).

An example of creating a red shadow, which is 8px big both horizontally and vertically, with a blur effect of 10px:

filter: drop-shadow(8px 8px 10px red);

Tip: This filter is similar to the box-shadow property.
grayscale(%) Converts the image to grayscale.

0% (0) is default and represents the original image.
100% will make the image completely gray (used for black and white images).

Note: Negative values are not allowed.
hue-rotate(deg) Applies a hue rotation on the image. The value defines the number of degrees around the color circle the image samples will be adjusted. 0deg is default, and represents the original image.

Note: Maximum value is 360deg.
invert(%) Inverts the samples in the image.

0% (0) is default and represents the original image.
100% will make the image completely inverted.

Note: Negative values are not allowed.
opacity(%) Sets the opacity level for the image. The opacity-level describes the transparency-level, where:

0% is completely transparent.
100% (1) is default and represents the original image (no transparency).

Note: Negative values are not allowed.
Tip: This filter is similar to the opacity property.
saturate(%) Saturates the image.

0% (0) will make the image completely un-saturated.
100% is default and represents the original image.
Values over 100% provides super-saturated results.

Note: Negative values are not allowed.
sepia(%) Converts the image to sepia.

0% (0) is default and represents the original image.
100% will make the image completely sepia.

Note: Negative values are not allowed.
url() The url() function takes the location of an XML file that specifies an SVG filter, and may include an anchor to a specific filter element. Example:

filter: url(svg-url#element-id)
initial Sets this property to its default value. Read about initial
inherit Inherits this property from its parent element. Read about inherit

Más ejemplos

Ejemplo de desenfoque

Aplicar un efecto de desenfoque a la imagen:

img {
  filter: blur(5px);
}

Ejemplo de desenfoque 2

Aplicar una imagen de fondo borrosa:

img.background {
  filter: blur(35px);
}

Ejemplo de brillo

Ajuste el brillo de la imagen:

img {
  filter: brightness(200%);
}

Ejemplo de contraste

Ajuste el contraste de la imagen:

img {
  filter: contrast(200%);
}

Ejemplo de sombra paralela

Aplique un efecto de sombra paralela a la imagen:

img {
  filter: drop-shadow(8px 8px 10px gray);
}

Ejemplo de escala de grises

Convierte la imagen a escala de grises:

img {
  filter: grayscale(50%);
}

Ejemplo de rotación de tono

Aplicar una rotación de tono en la imagen:

img {
  filter: hue-rotate(90deg);
}

Invertir ejemplo

Invierta las muestras en la imagen:

img {
  filter: invert(100%);
}

Ejemplo de opacidad

Establece el nivel de opacidad de la imagen:

img {
  filter: opacity(30%);
}

Ejemplo de saturación

Saturar la imagen:

img {
  filter: saturate(800%);
}

Ejemplo sepia

Convierte la imagen a sepia:

img {
  filter: sepia(100%);
}

Uso de múltiples filtros

Para usar varios filtros, separe cada filtro con un espacio. Tenga en cuenta que el orden es importante (es decir, usar escala de grises() después de sepia() dará como resultado una imagen completamente gris):

img {
  filter: contrast(200%) brightness(150%);
}

Todos los filtros

Una demostración de todas las funciones de filtro:

.blur {
  filter: blur(4px);
}

.brightness {
  filter: brightness(0.30);
}

.contrast {
  filter: contrast(180%);
}

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

.huerotate {
  filter: hue-rotate(180deg);
}

.invert {
  filter: invert(100%);
}

.opacity {
  filter: opacity(50%);
}

.saturate {
  filter: saturate(7);
}

.sepia {
  filter: sepia(100%);
