safari css filter blur

Today I Learned

How to fix filter: blur() performance issue in safari.

The filter: blur() property in css may come in handy in some situations, but you should know of a side effect it has in Safari (tested on version 15.1 as of this writing).

The issue is a nasty performance drop around the element on which the filter is used, making every other interaction extremely slow. And it happens in Safari only. In other browsers everything works well.

One solution I've found so far is to use transform: translate3d(0, 0, 0) along with filter on the same element, to force the browser use GPU acceleration for that particular element instead of the CPU.

The Use of filter

The CSS filter property adds visual effects to images or other elements without the use of photo-editing applications such as Adobe Photoshop:

You can set and animate multiple filters:

In the following sections, we will discuss each CSS filter in detail.

Note: if a filter uses percentages as values, decimal values are accepted as well (75% will be the same as 0.75).

Modifying image colors

Most of the CSS filters allow you to manipulate the color of the image. Let's review them using illustrative code examples.

brightness()

The CSS brightness() filter sets a linear multiplier to images:

Values lower than 100% make images darker . Values higher than 100% make images brighter .

The CSS contrast() filter controls the contrast of images:

Values under 100% lower the contrast, and those over 100% raise it.

hue-rotate()

The hue-rotate filter in CSS gives images the hue rotation effect:

The value of angle indicates the number of degrees around the color circle the input samples will be set to. The default value of 0 degrees does not change the image at all.

The CSS opacity() filter applies a specified level of transparency to the image:

The value of 100% leaves the original transparency of images, and 0% makes it completely transparent. You cannot use negative values.

The CSS saturate() filter sets the intensity of colors in images:

The value of 0% turns the image black and white . You can apply values over 100% as well, but this will result in very high color intensity. You cannot use negative values.

Converting color schemes

To change the color scheme for the image completely, you can use three CSS filters: grayscale() , sepia() and invert() .

grayscale()

CSS grayscale filter creates black and white images:

You can control the proportion of the CSS grayscale by indicating specific percentages: 100% creates a completely grayscale image, and 0% does not change the image at all. Choose any value between these two to tone down the colors as much as you need.

CSS sepia() filter applies a reddish-brown color to images:

A 100% value turns images fully sepia . The filter won't work with negative values.

The invert() CSS filter inverts the image color scheme, which means each color becomes its exact opposite. For instance, red becomes cyan, and green becomes magenta:

Other visual CSS filters

The CSS blur() adds a Gaussian blur to images. You can add length values in the parentheses and indicate how many pixels will the effect blend into each other:

Note: CSS blur() does not accept percentages .

drop-shadow()

The CSS drop-shadow() filter applies a shadow effect to images:

CSS drop-shadow can have five values:

• offset-x and offset-y indicate the shadow offset .
• blur-radius indicates how blurred the shadow is.
• spread-radius indicates how much space the shadow takes.
• color indicates the color of the shadow.

Applying multiple filters

You can combine several CSS filters to get even better results. To define multiple effects, you need to write them in a single statement, separating them by commas.

The following example uses both CSS blur() and brightness() :

Animating filters

CSS filters are animatable . Therefore, you can create different combinations and transform images:

backdrop-filter

The backdrop-filter property in CSS is used to apply filter effects ( grayscale , contrast , blur , etc) to the background/backdrop of an element. The backdrop-filter has the same effect as the filter property, except the filter effects are applied only to the background and instead of to the element’s content.

Classic example:

Filtered backgrounds without backdrop-filter

Before backdrop-filter , the only way to add a filtered background was to add a separate “background” element, position it behind the foreground element(s) and filter it like so:

The backdrop-filter property allows you to eliminate this extra “background” element and apply filters to the backdrop directly:

At the time of writing, backdrop-filter is part of the Filter Effects Module 2 Editor’s Draft and is not officially part of any specification. Browser support is currently limited (see below).

can be any one of the following:

• brightness()
• drop-shadow()
• grayscale()
• hue-rotate()
• url() – (for applying SVG filters)

You can apply multiple <filter-function> s to a backdrop, like so:

See the W3C Filter Effects Module Working Draft for acceptable values for each of the filter functions.

For a comprehensive look at filter functions and nifty ways to use them together, see the filter almanac entry on CSS-Tricks .

The following Pen is forked from an example in Robin Rendle’s article exploring backdrop-filter .

This feature is not Baseline because it does not work in some of the most widely-used browsers.

• See full compatibility
• Report feedback

The backdrop-filter CSS property lets you apply graphical effects such as blurring or color shifting to the area behind an element. Because it applies to everything behind the element, to see the effect the element or its background needs to be transparent or partially transparent.

No filter is applied to the backdrop.

A space-separated list of <filter-function> s or an SVG filter that will be applied to the backdrop. CSS <filter-function> s include blur() , brightness() , contrast() , drop-shadow() , grayscale() , hue-rotate() , invert() , opacity() , saturate() , and sepia() .

Create OS-style backgrounds with backdrop-filter

Blurring and color shifting behind an element.

Historically, these techniques were difficult to implement on the web, requiring less than perfect hacks or workarounds . In recent years both Safari and Edge have provided these capabilities through the background-filter (and alternatively, the -webkit-backdrop-filter ) property, which dynamically blends foreground and background colors based on filter functions. Now Chrome supports background-filter , starting in version 76.

Browser support

Browser Support

For performance reasons, fall back to an image instead of a polyfill when backdrop-filter isn't supported. The example below shows this.

• The backdrop-filter property applies one or more filters to an element, changing the appearance of anything behind the element.
• The overlaying element must be at least partially transparent.
• The overlaying element will get a new stacking context.

CSS backdrop-filter applies one or more effects to an element that is translucent or transparent. To understand that, consider the images below.

The image on the left shows how overlapping elements would be rendered if backdrop-filter were not used or supported. The image on the right applies a blurring effect using backdrop-filter . Notice that it uses opacity in addition to backdrop-filter . Without opacity , there would be nothing to apply blurring to. It almost goes without saying that if opacity is set to 1 (fully opaque) there will be no effect on the background.

The backdrop-filter property is like CSS filters in that all your favorite filter functions are supported: blur() , brightness() , contrast() , opacity() , drop-shadow() , and so on. It also supports the url() function if you want to use an external image as the filter, as well as the keywords none , inherit , initial , and unset . There are explanations for all of this on MDN , including descriptions of syntax, filters, and values.

When backdrop-filter is set to anything other than none , the browser creates a new stacking context . A containing block may also be created, but only if the element has absolute and fixed position descendants.

You can combine filters for rich and clever effects, or use just one filter for more subtle or precise effects. You can even combine them with SVG filters .

Design techniques and styles previously reserved for operating systems are now performant and achievable with a single CSS declaration. Let's look at some examples.

Single filter

In the following example, the frosted effect is achieved by combining color and blur. The blur is supplied by backdrop-filter , while the color comes from the element's semi-transparent background color.

Multiple filters

Sometimes you'll need multiple filters to achieve the desired effect. To do this, provide a list of filters separated by a space. For example:

In the following example, each of the four panes has a different combination of backdrop filters while the same set of shapes are animated behind them.

This example shows how to blur a semi-transparent background to make text readable while stylistically blending with a page's background.

Text contrast on dynamic backgrounds

As stated earlier, backdrop-filter allows performant effects that would be difficult or impossible on the web. An example of this is changing a background in response to an animation. In this example, backdrop-filter maintains the high contrast between the text and its background in spite of what's going on behind the text. It starts with the default background color darkslategray and uses backdrop-filter to invert the colors after the transformation.

More than 560 of you have upvoted the Chromium bug over the past few years, clearly marking this as a long awaited CSS feature. Chrome's release of backdrop-filter in version 76 brings the web a step closer to truly OS-like UI presentation.
