QUESTION
I've been upgrading my CRA project to TailwindCSS 3, but now CSS nesting no longer works. Upon starting the server, the console spits out:
...ANSWER
Answered 2022-Feb-03 at 18:38This is mostly just bad news.
Create React App's Tailwind support means that they will detect tailwind.config.js in the project and add tailwindcss to their existing postcss configuration. Source in CRA
The guide that Tailwind offers on their site creates a dummy postcss.config.js - Making changes in this file does not change the actual postcss configuration. (misleading if anything)
This is a known issue currently - Github discussion on Tailwind support PR between Adam Wathan (Tailwind founder) and Ian Sutherland (CRA maintainer). But it does not seem like there is an intention to be fixed soon.
If you want to use nesting (or any PostCSS plugin really) is to eject from CRA using:

In a fresh Laravel 9 installation, the URL processing from Laravel Mix does not work anymore.

...ANSWER
Answered 2022-Feb-22 at 10:55Actually moving the css imports into resources/js/app.js solves this problem. However, this results in the imported css to be included in the public/js/app.js, not the public/css/app.css.
QUESTION
I'm trying the create a 3D subscene with objects being labelled using Label objects in a 2D overlay. I've seen similar questions to mine on this subject, and they all point to using the Node.localToScene method on the node to be labelled in the 3D space. But this doesn't seem to work for my case. I've taken example code from the FXyz FloatingLabels example here:
The Label objects need to have their positions updated as the 3D scene in modified, which I've done but when I print out the coordinates returned by the Node.localToScene method, they're much too large to be within the application scene, and so the labels are never visible in the scene. I've written an example program that illustrates the issue, set up very similarly to the FXyz sample code but I've created an extra SubScene object to hold the 2D and 3D SubScene objects in order to plant them into a larger application window with slider controls. The 3D scene uses a perspective camera and shows a large sphere with coloured spheres along the x/y/z axes, and some extra little nubs on the surface for reference:

For starters, there is one subScene, not two.

ANSWER
Answered 2021-Dec-25 at 20:47You need to add a config js file for the tailwind engine, inside the config file use content attribute to define where is your HTML or JS files, the new engine automatically looks inside these files and compiles only the classes that you used.

I'm looking for ways to count the number of trailing newlines from possibly binary data either:
- read from standard input
- or already in a shell variable (then of course the "binary" excludes at least 0x0) using POSIX or coreutils utilities or maybe Perl.
This should work without temporary files or FIFOs.
When the input is in a shell variable, I already have the following (possibly ugly but) working solution:

I want to create dark mode for a web site which use bootstrap. I have to add new root class which includes all boostrap colors. Here is my colors.scss:
...ANSWER
Answered 2021-Aug-07 at 20:32As explained here, there's no way to attach a class to :root. However, you don't need this to achieve what you want.
Simply make a dark class then you can add that as desired to the html or body tag.
Make all the needed theme color changes inside .dark{}, and then @import "bootstrap". When .dark doesn't exist on the body, the theme colors will return to Bootstrap defaults.
