Propriedade do filtro CSS


Exemplo

Altere todas as imagens para preto e branco (100% cinza):

img {
  filter: grayscale(100%);
}

Dica: Mais exemplos de "Experimente você mesmo" abaixo.


Definição e uso

A filterpropriedade define efeitos visuais (como desfoque e saturação) para um elemento (geralmente <img>).

Valor padrão: Nenhum
Herdado: não
Animavel: sim. Leia sobre animáveis
Versão: CSS3
Sintaxe JavaScript: object .style.filter="grayscale(100%)"

Suporte ao navegador

Os números na tabela especificam a primeira versão do navegador que oferece suporte total à propriedade.

Números seguidos por -webkit- especificam a primeira versão que funcionou com um prefixo.

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

15.0 -webkit-


Sintaxe CSS

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

Dica: Para usar vários filtros, separe cada filtro com um espaço (consulte "Mais exemplos" abaixo).


Funções de filtro

Nota: Os filtros que usam valores percentuais (ou seja, 75%), também aceitam o valor como decimal (ou seja, 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

Mais exemplos

Exemplo de desfoque

Aplique um efeito de desfoque à imagem:

img {
  filter: blur(5px);
}

Exemplo de desfoque 2

Aplique uma imagem de fundo desfocada:

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

Exemplo de brilho

Ajuste o brilho da imagem:

img {
  filter: brightness(200%);
}

Exemplo de contraste

Ajuste o contraste da imagem:

img {
  filter: contrast(200%);
}

Exemplo de sombra projetada

Aplique um efeito de sombra à imagem:

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

Exemplo de escala de cinza

Converta a imagem para tons de cinza:

img {
  filter: grayscale(50%);
}

Exemplo de rotação de matiz

Aplique uma rotação de matiz na imagem:

img {
  filter: hue-rotate(90deg);
}

Exemplo de inversão

Inverta as amostras na imagem:

img {
  filter: invert(100%);
}

Exemplo de opacidade

Defina o nível de opacidade da imagem:

img {
  filter: opacity(30%);
}

Exemplo Saturar

Sature a imagem:

img {
  filter: saturate(800%);
}

Exemplo Sépia

Converta a imagem para sépia:

img {
  filter: sepia(100%);
}

Usando vários filtros

Para usar vários filtros, separe cada filtro com um espaço. Observe que a ordem é importante (ou seja, usar grayscale() depois de sepia() resultará em uma imagem completamente cinza):

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

Todos os filtros

Uma demonstração de todas as funções do filtro:

.blur {
  filter: blur(4px);
}

.brightness {
  filter: brightness(0.30);
}

  filter: contrast(180%);
}
