Hey!
Do you have a repo where we can have a look? Is the @tailwind base; directive present in your CSS file? It's responsible to set some CSS variables, including stuff for filters, so make sure it's there.

I think I've figured out the source of the problem. At least it was the source of the problem for me 😇 In production, my tailwind code was getting run through sass, and sass was tossing out the last backdrop filter variable assignment for some unknown reason. So I should have had: *, ::before, ::after {
--tw-backdrop-blur: ;
--tw-backdrop-brightness: ;
--tw-backdrop-contrast: ;
--tw-backdrop-grayscale: ;
--tw-backdrop-hue-rotate: ;
--tw-backdrop-invert: ;
--tw-backdrop-opacity: ;
--tw-backdrop-saturate: ;
--tw-backdrop-sepia ;
}But in my case it left out the sepia variable. So when the browser was trying to resolve I could have fixed it a couple of different ways. I could have manually declared the --tw-backdrop-sepia variable. But what I ended up doing was removing sass from the pipeline and going with an all postcss pipeline which didn't have the bug. Now that all the backdrop variables are initialized, the class is working as intended. |

3.0.11 works, but it's because 3.0.12 added the variable declarations that sass was mangling. This is the PR that introduced the changes that are causing the problems listed here: #6926. But I don't think the problem we're all experiencing is due to a bug in that PR, it's due to a bug elsewhere in our respective build pipelines. My reasoning for this is that if you strip away everything else, and just use the Tailwind CDN, it works fine: https://play.tailwindcss.com/My70K5zys8 |

I see, good information here. I'll play around a bit, but unfortunately for me, I cannot remove sass as I am using tailwind in conjunction with a rails app. rails uses webpacker, which in its current version lists looks like webpacker v6, which is due out soon, drops sass as a dependency, although I'll still have issues as some of the libraries I bring in to my app contain sass files. |

I'm using webpacker as well. You don't have to remove sass from your dependencies, you just need to remove it from the build pipeline that handles tailwind. So the sass loader only handles I'll see if I can get you more details on my exact setup tomorrow when I'm back in front of it. |

Hi all! This appears to be, at least in some of the cases, a bug in postcss parsing that doesn't mix well with some cssnano optimizations. Can you upgrade your projects to the latest versions of postcss (>= 8.4.6) and cssnano and see if the problem disappears? |

|
Unfortunately no change in build result after updating postcss. |

|
ah that's a bummer so it appears that more than just an postcss + cssnano issue. As far as Tailwind CSS goes it is generating the appropriate CSS in dev or production builds. So other PostCSS plugins, build tooling, or minification appears to be the issue here. |

In my use case I'm not using tailwind base because it saves me some bytes, ExampleRemember to use a background with an alpha, like I'm only using this: <div className="backdrop-blur-md backdrop-saturate-50 bg-[rgba(255,255,255,0.8)]">tailwind 3.0.21 adds this snippet: .backdrop-saturate-50 {
--tw-backdrop-saturate: saturate(.5);
}
.backdrop-blur-md, .backdrop-saturate-50 {
backdrop-filter: var(--tw-backdrop-blur) var(--tw-backdrop-brightness) var(--tw-backdrop-contrast) var(--tw-backdrop-grayscale) var(--tw-backdrop-hue-rotate) var(--tw-backdrop-invert) var(--tw-backdrop-opacity) var(--tw-backdrop-saturate) var(--tw-backdrop-sepia);
}
.backdrop-blur-md {
--tw-backdrop-blur: blur(12px);
}On this print bellow, devtools shows in blue color the custom properties applied to the backdrop-filter, just two out of nine.
The snippet above does not work as expected, but this script bellow does work: .backdrop-saturate-50 {
--tw-backdrop-saturate: saturate(.5);
}
.backdrop-blur-md, .backdrop-saturate-50 {
backdrop-filter: var(--tw-backdrop-blur) var(--tw-backdrop-saturate);
}
.backdrop-blur-md {
--tw-backdrop-blur: blur(12px);
}Work-around-ishPre-defined all backdrop related custom properties even though your project doesn't need them, so the backdrop-filter from tailwindcss will evaluate the correct CSS expression. Problem "solved", what do you think? |

Hey everyone! I have the same problem using filters (filter and backdrop-filter). It works on my local machine in dev mode but it won't work when running it in production. What fixed it for me was adding a custom class where the filter is set by me like (not my preferred solution but it works): Somehow empty variables get stripped in the production build process of NuxtJS or a plugin that's used in there. Thank you for reading. Have a great day! Best wishes |

Hello. I don't use nuxt.js but I had a similar problem. Fix was to not minify CSS. I use gulp scripts to run development and build steps. For dev: I use a For production: gulp first inlines the CSS between It turns out, minification breaks the backdrop blur for me and setting it to I hope this can help someone. Good days! |

Chrome (Version 98.0.4758.109) on Mac obviously has a bug. The drop-shadows based on the filter utility do not work as expected. The css var defaults are ignored. Once you check one css var in the developer tools all css var defaults are respected. |

I have the same issue. Css error because of the empty values for some vars. CSS: I don't even use filters, so I don't understand why these variables are added. config: The exact same setup, where I change content for purge with Tailwind 2 works correctly. The variables are added without causing an error in the output. |

I just encountered this issue in production too. Using postcss (8.4.12) with cssnano (5.1.5) with latest (3.0.23) TailwindCSS. Filters worked in development, not in production. Fixed (for now) by downgrading TailwindCSS to 3.0.11 from advice in this thread This definitely seems like a bug to me. |

If this is an issue for anyone, the best way to actually push things forward is to open an issue that includes a minimal reproduction 👍 We aren't seeing this on our own projects, and any time we've looked into it the real issue has been a bug in whatever CSS minifier was being used. But we have no issues that we've seen using cssnano for our stuff. |

Hi @adamwathan , thanks for your reply and for your awesome framework! I opened this as an issue, but it got moved to discussions somehow. As a check I created a new Nuxtjs project with only Tailwindcss included like the Tailwindcss doc explains: https://tailwindcss.com/docs/guides/nuxtjs I created a div with some text and a div overlay with blur applied to it. But when generating static html/css it doesn't apply the blur anymore: The only difference I see is this: Could that be the issue? Adding or removing Hope you guys can use this input.

Thank you @jasperverbeet, this was insightful and I thought it would actually fix the issue. Although I was not able to fix it by simply adding a peerDependencies. My NuxtJS is pretty minimal I'm not sure what could be interfering. Here is what it looks like after adding the dependency and running npm explain cssnano. I am using the same nuxt version as you (2.15.8). I am curious what package and version of TailwindCSS you're using. I am using @nuxtjs/tailwindcss (5.1.3) Are you using tailwindlabs/tailwindcss? Do you think it matters what package I am using? Cheers! |

Hmmm weird, maybe I mixed things up or something. I created a local prototype and the issue disappeared for me after I added the peerDependency. The issue was introduced in 3.0.12: v3.0.11...v3.0.12, somehow the empty CSS variables with the Nuxt CSS optimizer remove the empty variables entirely. |

Same issue here with create-react-app. When building our app, all the empty custom variables like --tw-backdrop-brightness, --tw-backdrop-contrast got deleted from the css, which was causing issues with the backdrop filter. The workaround we ended up using, was to add a custom plugin in the tailwind.config.js to override the existing backdrop-blur plugin from tailwind. Basically we just reused the one from tailwind but updated it by adding a fallback for each variable (--tw-variable-name,) In that way, even if the variable is not defined in the css, there is a fallback that is set to an empty value.

Reproduction URL
Describe your issue
I have a div on top of an image with backdrop blur applied to it. During development everything looks fine. After building, the backdrop filter blur isn't working, but the css is there. Not tested with other filters.
I'm using the class backdrop-blur-lg and generates:
.backdrop-blur-lg { --tw-backdrop-blur: blur(16px); -webkit-backdrop-filter: var(--tw-backdrop-blur) var(--tw-backdrop-brightness) var(--tw-backdrop-contrast) var(--tw-backdrop-grayscale) var(--tw-backdrop-hue-rotate) var(--tw-backdrop-invert) var(--tw-backdrop-opacity) var(--tw-backdrop-saturate) var(--tw-backdrop-sepia); backdrop-filter: var(--tw-backdrop-blur) var(--tw-backdrop-brightness) var(--tw-backdrop-contrast) var(--tw-backdrop-grayscale) var(--tw-backdrop-hue-rotate) var(--tw-backdrop-invert) var(--tw-backdrop-opacity) var(--tw-backdrop-saturate) var(--tw-backdrop-sepia); }At the end when I delete the undefined filters from the css in the console (I only use backdrop blur), the backdrop filter does its job again (Chrome and Safari).
