Night-Mode | : crescent_moon : 夜间助手，可设置网页背景色的浏览器扩展（已在谷歌、火狐、Microsoft

I have a simple JavaScript light/dark mode button but I don't know how to make the transition ease out as well as in. Here's the CSS:

It has been brought to my attention that a website I'm helping out with sometimes has problems with span elements being injected. Those spans will break the whitespaces and make the text hard to read. Those spans look something like this:

I've been building a camera app using the AVFoundation and wanted to add NightMode support to it. Apple features a stunning implementation for this, more about it can be read here: https://www.macrumors.com/guide/night-mode/

Now, the only "properties" I can find about "night mode" would be low-light boost, which only seems to be an iPhone 5 feature https://developer.apple.com/documentation/avfoundation/avcapturedevice/1624602-islowlightboostenabled https://forums.developer.apple.com/thread/52574

I'd like to take advantage of the apple native night mode and implement it into my camera app. Is there any way to do so? Is this a feature that might be added to the SDK within the next releases? Did I miss something in the SDK?

I want to add animation for switching theme from light to dark or vice versa in flutter like telegram do :

telegram's switch animation

telegram's switch animation

can't see any way to do it in flutter, is it possible in flutter?

thx for any answer

I know there is a new feature on Android Q to finally support dark theme (wrote here about detecting it).

I also know that there is "Night Light" feature (here) that makes the screen become more yellow-ish.

Supporting the theme choosing manually is something I've done for years (using simply setTheme on Activity's onCreate's first line of code), but I want to know if there is something automatic that will allow me to set it even before the app really starts, in the splash screen.

It seems a very old feature (since API 8!) has existed on Android for a very long time, of having "night" qualifier in the resources, and I never even tried it.

Sadly, because "dark theme" and night-related stuff are now more often talked about as the new features (here for example), I can't find what's the old one all about.

Looking at some articles and documentations, though, it seems it's almost completely manual:

• https://developer.android.com/reference/android/app/UiModeManager.html - says I can set it myself, including set it to be automatic. However, it seems it's related to being docked, and maybe even car-mode.

• https://google-developer-training.github.io/android-developer-fundamentals-course-concepts/en/Unit%202/53_c_providing_resources_for_adaptive_layouts.html - Says I can set "night" as a qualifier, and there is a "night mode".

I tried to set the various themes accordingly:

res/drawable/splash.xml

Is there any CSS prefix for night mode or javascript event that trigger when user change the mode? I want custom colors for the element if the user enables night mode from the browser setting.

Thanks

I know the Stylus and Stylish (not recommended) browser extensions that can re-style a given website (basically by customizing CSS).

In this comment, the author states this can be done via "user stylesheets".

How is it possible to use "user stylesheets" to modify the style of www.example.com and a different style for www.example2.com?

Is it something that can be done without requiring a third-party browser extension, if so, how/where in the browser options should we add our custom CSS?

The following js code allows me, with buttons, to dynamically change color to the body class, it works great. However, in addition to backgroundColor I have tried to use other CSS rules, for example color, borderColor, on a button, and it works very well.

1) If I use box-shadow or boxShadow does not seem to work. Am I wrong or is there a list of CSS rules I can use?

2) $('h2').css('backgroundColor', '#000'); to get a change of color on mouse over I tried $('h2:hover').css('backgroundColor', '#ff0000'); but this does not work. Also in this case the reason is that dynamically you cannot use: hover? Or am I wrong?

TL,DR;

ContextCompat.getColor() does not use the night colors (values-night/colors.xml) though it should when night mode is enabled.

Here is the problem:

Hi everyone,

So I'm implementing a dark theme for my Android app, I call this to enable it : AppCompatDelegate.setDefaultNightMode(AppCompatDelegate.MODE_NIGHT_YES);

I have set colors in values/colors.xml and there dark version in values-night/colors.xml. The colors changes well depending on the nightMode, BUT :

when I use ContextCompat.getColor(getApplicationContext(), R.id.myColor), it uses the normal colors (values/colors.xml) and not the night colors (values-night/colors.xml).

In my build.gradle, I have set these :
