I'm using Codekit to minify all my CSS via Sass. This works great but causes an issue when inspecting the code as everything appears on line 1! I use the lines as a quick way to find the code I'm looking for.
I use the Codekit plugin for Coda, which means every time I make a change to a .scss file and save, it just auto compiles the code.
I guess everyone will tell me not to compile the code until launch, in an ideal world that's great but there will ALWAYS be a need to inspect the code without once it's all been compiled.
Is there a way around this? Or is this a downside of compiled code? What processes do people go through to get to the minified code? How can I tell which .scss the change is in?
I could set it to be less compressed so it's not all on one line but I would then lose the benefits of compressing it.
These are the settings I have Codekit set to:
Codekit supports Source Maps, which will let Google Chrome show you the original code even after minification.
In your compilation settings, check the Create a source map box for SASS.
For more information, check out this Team Treehouse article (the article deals with JavaScript, but the same principle applies to CSS too) and the Codekit SASS documentation.

I see this html template, and inspect it using Chrome inspection tool.
I'm surprised to know that my browser can detect the scss files instead of the compiled css one.
Then, I push Ctrl+U to view the page source, try to find 'scss' but it gives nothing in result.
So, how does the browser know the scss files?
P.S. I'm new to scss/sass/css pre-processor things
You can read this article for more about Sourcemaps: https://www.html5rocks.com/en/tutorials/developertools/sourcemaps/
This is mainly used for debugging and most of the times is stripted from production environments (in this case I guess they left it for people to check the actual source code and learn as you did :P)
What you are seeing is called Sourcemaps. Sourcemaps allow you to see the original source instead of the compiled CSS. This is usually used for debugging.
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.
By default SASS looks at the filename and determines whether to make a css file out of it. I'm wondering if there is a way to prevent this from happening.
We're building a large website and lots of front-end developers are editing the css, but we only have one dev server. Sure some things you can see happen locally, but often you can only see the real rendered way on the server.
So, when I push my compiled css file to the server, my co-workers' css gets clobbered until s/he commits and I do an svn:update, etc, etc.
However, if we were working in different SASS file, and those css files were getting created, I would only have to push up, say, the forms.css file instead of the whole thing.
Then for Production, we'd put it back to the way SASS normally works.
The only other way I can figure to do this is to do a mass rename of files, which seem very messy.
Thanks in advance.
The entire point of partials is that they don't get compiled into files. If you want a sass file to be turned into a css file, remove the underscore.
Your real problem seems the be that you're putting compiled CSS in your version control. Don't do that. Only commit Sass, and compile it into CSS server-side with a post-receive hook or something.
I am searching for a solution on how to implement SASS into an asp.net project. I have searched a lot but have found no example on the web. As far as I know some kind of JavaScript file will be needed in project in order for it to work.
Can anybody please share a sample aspx page with one or two textboxes with SASS applied to it?
Sass is written in Ruby, not JavaScript. There are a few JS compilers, but none of them are official, and none of them should ever be considered for use outside of development.
Outside of Ruby on Rails, there is no integration. You put your source files where appropriate and use the Sass compiler to compile it and place the CSS file into your public directory. Whether you use the command line or an application like Scout is up to you.
I personally use the command line to continuously watch my Sass files as I am working on them, and it only takes a second or 2 to compile (just slightly longer than it takes to alt-tab so I can refresh and see how it looks).
I'm considering using less in an upcoming project but have been trying to figure out the best way to work with it while in development.
Usually when developing a site I'll write my html and css then start testing it in the browser, see how it looks, refine, reload, and repeat the whole process until I'm happy with how everything looks.
A crucial part of the process is using the Inspect Element feature in the browser to identify the piece of CSS I need to change. Usually just by looking at the line number I know exactly where to go in my CSS file.
But if I use Less (or any other method of combining/compressing my CSS) it makes the line numbers useless. I know I could use Find to search for the section of code but line numbers are much faster.
This is especially true when working on a project that involves other developers or large CSS files.
I just wondered how others deal with this, or maybe there's a better process?
Minified CSS really should only be going out to the production version of your site. When you're performing tests/changes etc, this should all be done in some test or development version of your site in a secondary server area where you can have the line-numbers version of css available. The same would go for JavaScript. On the production viewable copy, you want it minified. In development, you don't.
In any event, you should always have 2 copies of your css. The first copy is the primary source copy that is your development copy. It has all of your properly formatted styles with line-breaks in it. The other is the very latest minified version of your css that went to production. This will allow you to switch between the 2 files rapidly in the event that you need to work something out, assuming your site uses some sort of templated delivery (layout pages, master pages, or whatever).
The minified version will only be useful in the final delivery. All other needs should use the master copy. It might not be a bad idea to put a configuration in server-side portion of your site that determines what style sheet to use. That way you can simply change a configuration setting and go into a "debug" mode.
I agree with Joel - that's how I handle it. A build script minifies the CSS (and JS) before each release is FTP'ed to production. I just have a switch in PHP like:
if ($config->prod()) {
// incldue the minfied css
} else {
// include all the original files
}
Personnaly, I use an ant build script to make a production version:
it "condense" multiple css files in one
then it minify them with YUI compressor
same for scripts
(page recomposition to point to the newly generated files)
this way you divide your http request for those files, and gain some bandwith from 30% to 70% i'd say. depends on gzip also.
in my case, the dev version have:
18 css weighting 178ko
reduced down to 1 css at 96ko in the production version
I personally use tools to minify and inject the CSS into the browser each time i save my Less file. So i see each change immediately. This way it's pretty clear what just happened. I don't need the referencing line numbers that much any more.
I recently started using source maps, to see the correct file and line numbers (of my less files) when inspecting CSS in the browser again. I think that is what you are looking for. I personally don't need this extra fanciness that much.
