Quick Reference
The filter property defines visual effects (like blur and saturation) to an image element.
img {
filter: sepia(100%);
}
Values
| Default value | none |
| Inherited values | no |
| Can it be animated? | yes |
These are the allowed values.
| Filter | Description |
|---|---|
| none | Specifies no effects (default) |
| blur(px) | Applies a blur effect to the image; larger values mean more blur (0 is the default) |
| brightness(%) | Adjusts the brightness of the image
|
| contrast(%) | Adjusts the contrast of the image
|
| drop-shadow(h-shadow v-shadow blur spread color) | Applies a drop shadow effect to the image
|
| grayscale(%) | Converts the image to grayscale
|
| 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) |
| invert(%) | Inverts the samples in the image
|
| opacity(%) | Sets the opacity level for the image. The opacity-level describes the transparency-level, where:
|
| saturate(%) | Saturates the image.
|
| sepia(%) | Converts the image to sepia.
|
| 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 – for example: filter: url(svg-url#element-id) |
| initial | Sets this property to its default value |
| inherit | Inherits this property from its parent element |
Using JavaScript
The HTML element can also be styled using JavaScript and the element’s id.
document.getElementById('my_img').style.filter = 'sepia(100%)';
<button onclick='my_function()'>Click Here</button>
<script>
function my_function() {
document.getElementById('my_img').style.filter = 'sepia(100%)';
}
</script>
