Is there a way to add a blur effect to the moving elements in the background of a

For a project I'm currently working on involving a full screen styled Google Maps page, I am looking for a way (css, jQuery, or other options...) to overlay a header and slide-in sidebar with a blur effect similar to the iOS frosted/blur effect.

I am aiming to achieve something like the following example: Sample blurred header

The challenge I am facing is that I do not have control over what is beneath the header, and it constantly changes. This makes it impossible for me to use the 2 image trick to simulate a blurred background. Any suggestions or alternative approaches would be greatly appreciated!

Answer №1

Check out this informative post here, along with a related link for further reference here

The process outlined involves the following steps:

  1. Create the HTML layout
  2. Replicate the content section and convert it to canvas form
  3. Position the Canvas within the Header section
  4. Synchronize the scroll movements of the content area with the canvas in the header

Further down on the page, you'll find an example (the narrower one). There may be some missing elements causing slight spillage, but give scrolling a try. However, frequent changes in content could lead to performance issues. Proceed cautiously.

I'm not aware of any other method to accomplish the complex task you desire.

If you're looking to incorporate an external image, one potential approach is loading it into an svg container as a background and then applying a feGaussianBlur filter. However, the level of control over the markup may vary.

For a helpful overview on implementing blur effects, consider checking out this W3 Schools resource:

http://www.w3schools.com/svg/svg_fegaussianblur.asp

Here's a demonstration courtesy of jsfiddle (not my own):

https://jsfiddle.net/jamygolden/yUG5U/2/

To give you a sense of how the markup might look, here's an example snippet:

<svg id="svg-image-blur">
    <image x="0" y="0" id="svg-image" width="300" height="200" xlink:href="http://path/to.your/image.jpg" />

    <filter id="blur-effect-1">
        <feGaussianBlur stdDeviation="2" />
    </filter>
</svg>

And when it comes to styling with CSS:

#svg-image-blur { height: 200px; width: 300px; }
#svg-image:hover { filter:url(#blur-effect-1); }

Answer №3

Employ the backdrop-filter property as it is widely supported by modern browsers:

backdrop-filter: saturate(180%) blur(20px);
-webkit-backdrop-filter: saturate(180%) blur(20px);

Answer №4

Is it possible to use CSS blur effect?

-webkit-filter: blur(10px);
-moz-filter: blur(10px);
-o-filter: blur(10px);
-ms-filter: blur(10px);
filter: blur(10px);
