I found MS DOC about Css in razor. But it isn't work with Scss file.
I resolve this problem by creating two files: css and scss. And use sass --watch. But I need write this every time, when creating new component.
Unfortunately SASS is not supported for CSS Isolation feature of Blazor. At least, not at this moment.
In our project, we use CSS Isolation for the CSS component isolation feature, but we use SASS files to manage our theme, for style we want accros the application.
That being said, if you really need some SASS for an unique component, you totally can, by adding for example a wrapper with a specified id, and use this id in your scss file, with a dedicated name for it, for example MyComponent.scss.
In addition, I've found this article, but I preferred to not use it because it is a bit heavy to setup, but up to you: https://joren-thijs.medium.com/how-to-add-scss-support-to-blazor-cd2a62995441
You can use AspNetCore.SassCompiler which supports both normal and isolated scss. I believe it has a watch mode when using Blazor Server, WASM is not supported yet.
It can also do minification with source mapping.

I'm using dynamicaly generated classnames in React/Tailwind. I know that it doesn't supported. So I need to generate a css file including all Tailwind functionality. How can I achive it?
My advice would be to refactor the code so you support the "tailwind way" because loading the entire library will possibly hurt your performance ,if you are not going to do that you can add all the classes you do not want purged to the safelist in your tailwind.config.js
Here is a link to official doc

I have a web application with the back-end in node.js and front-end in react.js.
I have written the css using sass and am wondering if I am can somehow connect node and sass so that on request from the user (example font-size change) at the client-side a new css file can be generated and sent to the web application.
If this is possible that what module/library do i need to take a look at?
SCSS is a CSS precompiler. It's only use is to generate CSS when compiled. Write a simple syntax are generate the CSS for the browser to use it. Any use of SCSS other than this is not what it is made for.
Now coming to your use case, all you need is themeable CSS. If you need just the change in font-size or theme color, you don't even need an extra css. Explore CSS4 variables. Here is a very basic use of CSS4 for theming. https://dev.to/idoshamun/theming-with-css-variables-322f
I'm trying to customize the design of my ionic app, I don't know much about SASS, but based upon my research, most people have suggested or are customizing the defaults of ionic through the scss files. Since I don't know much about SASS, I was wondering if its safe to make changes to ionic's defaults through the ionic.css file.
Yes it is "safe" as long as you plan to never use sass! If you use sass it will overwrite what's in the ionic.css file.
Having said that, you should really just use sass as it will make your life a lot easier. You don't need to learn anything new to use sass because writing normal css in a sass file will work just fine.
You can then add bits of sass as you progress and pick them up.
As stated by Rob Dodson, style tags are now unavoidable with Web Components. I am trying to find a way to use LESS with this new tecnhology without having to paste the compiled CSS in my HTML document everytime I change something in the LESS file . Is there anyway to achieve that?
I am using Polymer.
Thanks!

You can make the client compile the LESS to CSS , you should definitely take a look at this :
http://lesscss.org/#client-side-usage
It is advised to compile it yourself to css in a production environment though !
Doing this client-side hardly seems like the corrent solution, especially at scale. For instance, do you really want 1000 web components in your app all including LessCSS and compiling on the client side?
Just compile server-side and include the compiled version in your html import. Apps like DocPad, make this a lot easier. For instance:
src/documents/components/my-component/my-component.css.less is your source file, and is compiled to out/components/my-component/my-component.css, which is accessible at /compoennt/my-component/my-component.css.
We use this workflow to also make use of javascript pre-processors like coffeescript, as well as post-processors like css auto prefixer, and bundlers like Browserify. See: https://stackoverflow.com/a/23050527/130638 for more info.
Simply compile your less and embed the generated CSS file via good old link tag.
I don't think that rob wanted to say that using style tags is the only way to go. You can still link to external stylesheets as you always did.
Why don´t you compile on server side using php compiler? Have a look here - http://leafo.net/lessphp/ -
To let you know, i´m using this compiler on my projects, on the server side without any kind of problems!!!!!!! :) IMO, it´s better to have the compilation work on the server side. I´m not totally 100% sure, but i think IE8 don´t recognize text/less
The way I have done this before is have individual .less or .scss file for each component and have it compile into the individual .css file which is then called into the respective component file. and finally vulcanize everything into a single file.
Incase you want to use a single CSS file, then use //deep// combinator or ::shadow pseudo elements in the CSS.
If you able to create the custom elements without using ShadowDOM then you can simply have all your less merge into a single CSS.
Honestly speaking I was unable to create a wc without shadowDOM in polymer. There is a long conversation on github on enabling / disabling and hacking a way to create a wc without shadowDOM here https://github.com/Polymer/polymer/issues/222
One solution would be to have the preprocessor translate .less files into .css and then linking them inside Polymer components, like explained in the official documentation: https://www.polymer-project.org/1.0/docs/devguide/styling#external-stylesheets
Unfortunately this is deprecated. So the other way to go could be to have another step that wraps the preprocessor-generated css files with a dom-module: this way you can follow the Polymer way including the style module inside your components, or using the css file compiled from less if you do things outside Polymer components.
I'm using Gulp for my build process and I found this module very useful:
https://github.com/MaKleSoft/gulp-style-modules
It creates, for every .less file I have in my sources, an .html file with a dom-module wrapped around it, ready to be included in the components' styles.
In my project i have a lot of css styles. Some of them are never used (not anymore). I check this manually with eclipse: i select text and then with "Search -> Text -> Project" i can find, if this style occurs only in the stylesheet or also in java files. Is there better way to check, which styles are currently used in my GWT project?
edit:
#Igor,Keith: thanks for the hint, but i'm not using the CssResource to insert my css file. Instead i use my index.html. And i want to remove the unused styles just for better overview. CssResource is not exactly, what i'm looking for.
If you use CssResource to inject your css file, GWT will handle pruning unused styles for you (just like it does in the case of unused code). It will also by default obfuscate it, so watch out for that. For a comprehensive explanation see the docs.
CssResource works best in combination with UiBinder. I'd recommend both - you even get cool features like compilation-time errors when you are missing a CSS style in your UiBinder xml files (or you misspelled it), among other cool/awesome things - again, check the docs for the full list.
GWT 2.0 added a feature called ClientBundle, which is a generic mechanism for bundling resource files such as images and CSS. If you bundle CSS files with ClientBundle (via the CssResource class), the GWT compiler can actually generate errors on unused CSS selectors.
The documentation is a bit rough, but here is the relevant part of the GWT docs:
http://code.google.com/webtoolkit/doc/latest/DevGuideClientBundle.html#Strict_scoping
In addition to detecting missing selectors, CssResource also supplements CSS itself, letting you use constants and conditionals within your CSS, even allowing you to specify different styles depending on which browser is being used. It also provides obfuscation and minification, among other things.
I'm still looking for a better solution. To solve the problem i've used the linux terminal instead eclipse for the search and that was faster.
