Dark Mode Beta - help us root out low-contrast and un-converted bits.Recently, I was browsing a post on Medium and I spotted a nice image loading effect. First, load a small blurry image, and then transition to the large image. I found it pretty neat and wanted to dissect how it was done. I have performed a WebPageTest test against this page on Medium where you can see how it loads too. Render a div where the image will be displayed.

Thus, they prevent reflows while the images are loaded since everything is rendered in its final position. This has also been referred to as intrinsic placeholders. Load a tiny version of the image. At the moment, they seem to be requesting small JPEG thumbnails with a very low quality e. Then, the image data is taken and passed through a custom blur function You can see it, a bit scrambled, in the main-base.

At the same time, the main image is requested. Once the main image is loaded, it is shown and the canvas is hidden. I have prepared this CodePen where I have implemented the same effect, though using CSS filters for the blur instead of a canvas see below more info about this variant.

You can see it better in full screen. I recommend that you use network throttling and disable cache to notice the full animation. Clearly, there is a lot of things going on to be able to render an image this way, and it can be discouraging to do something similar on your site. A few years ago it would have been impossible to do this animations and blur effects in a performant way, but the truth is that most of the times the latency is the bottleneck, not the device capabilities, and we can play with these visual explorations.

Lazy loading. Using JS for making the requests allows them to be in control of what images are requested. While all the small thumbnails are requested, the large images are only requests when they are within the viewport. Better placeholder. The thumbnails are very small, barely 2kB, which combined with the blurry effect allows for a better placeholder than a solid colour, without sacrificing payload.

Tailored image sizes. Medium serves different images sizes depending on the device that makes the requests, which optimises the weight of the page. Instead of making a request for the small thumbnails, it is possible to inline them using data URIs. This increases the size of the HTML, but accelerates the rendering of the placeholder, which is immediate one the markup is downloaded.

The blur effect allows these images to be really small. I did some tests with 0. By default, when a browser renders a small image scaled up, it applies a light blur effect to smooth the artefacts of the image. The effect can also be turned off for images like QR codes. Here is a demo, but you can see it better in full screen :.

Note how the artefacts are smoothen. Its support is quite wide aside from IE. The advantage of this technique is that you can easily tweak how much blur you want and everything is achieved using CSS.Learn Development at Frontend Masters. Filter effects in CSS have been around for a while, and together with things like blend modes, they bring new possibilities for recreating and manipulating stuff in the browser that we previously had to do in Photoshop.

Here, Emil explores a performance technique using one of the more forgotten filter effects — the filter function — as well as recreating it with SVG. This all starts with a post from the Facebook engineering team on how they load cover photo previews in their native apps. This is especially true on low-connectivity or mobile networks, which often leave you staring at an empty gray box as you wait for images to download. Ideally the image would be encoded into the initial API response of their app when getting the profile data.

But to fit inside this request, the image would have to be capped at bytes. Troublesome, as cover photos are over kilobytes in size. So how do you get something valuable out of bytes and how do we show the user something before the image is fully loaded?

The ingenious solution was to return a tiny image around 40 pixels wide and then scale that tiny image up whilst applying a gaussian blur. This instantly shows a background that looks aesthetically pleasing, and gives a preview of how the cover image would look. The actual cover image could then be loaded in the background in good time, and smoothly switched in. Smart thinking!

Big header background images and their performance drawbacks are definitely something that we can relate to when building for the web, so this is useful stuff.

We may try to avoid the downloading of heavy images, but sometimes we make the tradeoff to to achieve a certain mood. The best we can do in that situation is try to optimize the perceived performance, so we might as well steal this technique. The very first request will load the tiny image in inline CSS, then the high-res background comes after first render. In this example, we are using a background image, regarding it as decoration rather than part of the content.

In order to make use of smart sizing modes like the CSS values cover and containbackground images are probably the most common solution for these kinds of designs, but new properties like object-fit are making the same approach a bit easier for content images. Sites like Medium already use blurred content images to improve load times, but the usefulness of that technique is debatable — do the blurred images bring anything to the table if the loading technique fails? You can find the final example as a Pen.

The problem I am facing is being able to load my menu's individual HTML pages, as content is loaded via ajax. In my menu, when a link to example. What I don't want is to be loading everything via Ajax from 1 file this will be very messy for me. If you download the source and put a link in the navigation to go somewhere, you'll see it doesn't do anything.

However when I try and remove some Javascript, I manage to break the animation everytime. Is there some legend out there that knows how I can achieve directly linking to an html file or loading each pages content via ajax from an independent html file while keeping all the menu's animation in tact?
