Re: [blink-dev] Intent to remove: zoom CSS property

What's the latest on this topic? Is this still an ongoing discussion or is it decided to become deprecated from Chrome 117 onwards? Our application relies heavily on it so ideally we have at least a couple of months to adapt to this (and have some warnings in the console first a couple of relea

Not to our knowledge, but we’ll dig deep into this. However, I can confirm that simply using transform: scale is not one of them: I’ve just done this in our app, and immediately run into the same issues we’d seen the last time we tried: scroll performance is awful, there is scroll jumpiness (

Re: [blink-dev] Intent to remove: zoom CSS property

Similarly, online web design and authoring tools (like Framer, or our OSS project at Utopia) rely on the zoom property for working when "zoomed in". In Firefox (w/ scale as fallback) the result is a degraded (eg blurry) experience - sometimes severely so, especially when shadows, serif fonts, a

In a previous response it was stated that the removal of this property leads to only a small amount of code being removed, which I assume also means that there is little impact on reducing complexity in the engine. Maybe I missed it but is there an in-depth explanation of the intention and impa

I would like to point out that Microsoft Excel Online utilizes zoom CSS property heavily to perform the Excel grid zoom operations. Removing it would completely break our zoom functionality in the product and impact 100s of millions of users. On Thursday, April 20, 2023 at 10:42:17 PM UTC+3 Ch

Re: [blink-dev] Intent to remove: zoom CSS property

Back to the testing question. There are hundreds of blink web tests that set zoom via CSS. Most of them are not testing the zoom CSS feature itself (though some are) so most of them would need to be updated to test browser zoom situations. It's tractable, particularly if we modify the existing test

Re: [blink-dev] Intent to remove: zoom CSS property

Hey everyone, I currently depend on the `zoom` CSS property since using `scale` in conjunction with perspective transforms results in a significant color washout in Chrome. My primary goal is to achieve pixel-perfect precision, and I'd be more than willing to transition away from `zoom` if this

Re: [blink-dev] Intent to remove: zoom CSS property

I'm supportive of aligning with the CSSWG and Firefox here. But this does seem at least a little risky to me, so I think we need to carefully consider the launch plan. First, you'll have a flag so we can kill-switch it if we see any non-trivial breakage in practice, right? WebView seems particular

Not sure which e-mail you are referring to. I tried transform: scale(100) and I was pleasantly surprised to see that it did not make anything pixelated (I did not try raster image formats, of course, that must be pixelated even with zoom). I was worried it was not a good replacement, but it is for

Re: [blink-dev] Intent to remove: zoom CSS property

I seem to recall tests making use of CSS zoom. Is that not a concern? How do we write tests for issues that only manifest at particular browser zoom levels, because transform behaves differently than zoom (aka device scale factor)? Stephen. On Fri, Apr 14, 2023 at 8:14 PM Chris Harrelson wrote:
