The general error: SyntaxError: Invalid or unexpected token, referencing line 1 of index.css.
This is the result of encountering CSS syntax in a CSS file that I'm trying to import for styling.
Attempted fixes and experiments:
Deleted everything out of the CSS file and exported an empty JS module. This works, verifying that the import is treating it as a JS file, not CSS.
Removing the #import statement from line 1 of the CSS file. Of course, this fails to make a difference because the remaining CSS syntax throws the same error.
Paired down the Webpack config file to eliminate the surface area of the problem. Rendering should be handled by Webpack, so the issue may reside there. Config was very basic and set to handle CSS, SASS, JS, and JSX.
Tried importing the CSS file from other file locations, including the server's app.js file.
Tried making use of ExtractTextPlugin as an bundling alternative.
Tried making use of Isomorphic Style Loader.
All in all, given the attempted fixes and tests listed above, the issue seems unrelated to Webpack per se. It's as if the server side rendering is attempting to import the CSS file before Weback gets involved.
The fix, it turns out, was to use the ignore-styles package in our server app.js file:
require('ignore-styles')
The description as listed on the repo:
A babel/register style hook to ignore style imports when running in Node. This is for projects that use something like Webpack to enable CSS imports in JavaScript.
I have a really annoying issue where the bundler is not loading the file all.css correctly after publishing, resulting in my datepicker not being styled properly.
Here is the datepicker when debugging from Visual Studio:
And after publishing the application:
Where all.css simply contains
#import "base.css";
#import "theme.css";
#import "jquery-ui.css";
And bundleconfig.cs contains:
bundles.Add(new StyleBundle("~/Content/css")
.Include("~/Content/bootstrap.css")
.Include("~/Content/mystyles.css")
.Include("~/Content/themes/base/all.css"));
I noticed that the issue is resolved if I manually add
.Include("~/Content/themes/base/jquery-ui.css)
But this does not explain why this is happening in the first place.
Does anyone have any ideas or suggestions?
Thanks!
My team is using SitePrism for feature tests in a Rails 4 app, and we're currently restructuring our CSS assets in the project. One of the asset files includes a line that #imports from a subdirectory:
app/assets/stylesheets/lib/admin.scss.css:
#import "base/base-admin";
and app/assets/stylesheets/lib/base/base-admin.scss in turn includes:
#import "shared/reset";
#import "shared/colors";
#import "shared/breakpoints";
#import "shared/grids";
This all works fine in development in the browser (I get no errors from requests to lib/admin.css, and I see the CSS rules are applied to the page correctly).
But when I run our feature tests, I get
Failure/Error: #page.load
ActionView::Template::Error:
File to import not found or unreadable: base/base-admin.
Load paths:
/Users/duncanmalashock/ruby_projects/platform
/Users/duncanmalashock/ruby_projects/platform/.bundle/gems/ruby/2.2.0/gems/bootstrap-sass-3.3.4.1/assets/stylesheets
(in /Users/duncanmalashock/ruby_projects/platform/app/assets/stylesheets/lib/admin.scss.css)
However, none of the other assets are broken in the test environment. Why can't these be found?
This turned out to be a naming error. The suffixes on my manifest were ".scss.css", instead of ".css.scss" (which would have been correct).
The Asset Pipeline starts with the last suffix, and tries to run a process that matches it, then repeats with the next suffix in.
So the Pipeline was trying to #import a file in the wrong way (there's an #import directive in CSS and also differently behaving one in SCSS), which was leading to unexpected behavior.
I have made my first website using MVC 5 which works fine on my local machine but when I publish it to the server some of the CSS is not minifying correctly.

After trying to correct some of the errors and publishing again the error looks the same.
The strangest part is with bootstrap.css which I have slightly modified for the purpose of the website. When I publish it the changes are not in the bundle file. Is it possible that bootstrap is loaded from Bootstrap server and not my project?
bundles.Add(new StyleBundle("~/Content/cssmain").Include(
"~/Content/bootstrap.css",
"~/Content/site.css",
"~/Content/ilightbox.css",
"~/Content/bannerscollection_zoominout.css"));
I have also tried to do minification myself using web application but my changes are not visible and the files do not appear to be minified.
Any help is appreciated.
I resolved the problem bundling bootstrap.css by doing 2 things:
Include the bootstrap.css first in the bundle. The code sample in the question already does this, but I was not.
Add the official minified version (bootstrap.min.css) to the project in the same directory as the unminified version. This prompts the bundler to use the existing minified file instead of trying (and failing) to minify bootstrap.css itself. See the green arrow in the screenshot below.
Note that if you are using a specific theme, substitute bootstrap.css and bootstrap.min.css with the files provided by the theme. Here's the working code from my project that uses the spacelab theme:
bundles.Add(new StyleBundle(GetStyleBundlePath("bootstrap")).Include(
"~/Content/3rdParty/bootstrap.spacelab.css",
"~/Content/3rdParty/bootstrap-datepicker.css",
"~/Content/3rdParty/bootstrap-multiselect.css"));
For those that may stumble on this post... You can also resolve this by moving the #import to the first bundled item.
According to: http://webdesign.about.com/cs/css/qt/tipcssatimport.htm
#Import must always be first in the CSS document. When you bundle multipule CSS files together, it chains them into a single bundled css file. Since the second css file added to my bundle, in bundle config, contained an #Import at the start, as the files were chained together the #import appeared towards the middle of the newly merged document. Once I changed the bundle order the issue was resolved.
This is important to understand because although you can use the minified files provided by plugins like bootstrap any changes made to the non-minified files during development will not be added to the existing minified css file. Meaning you will have to make the changes twice, and navigate your way through the minified file.
Make sure the none of those .js files you are bundling end with //Some Comment. If a file ending with a double backslash // comment is tacked on to another dependent file it will be seen as one long comment causing the error you are seeing. I bet there is an //#Import at the end of one of your .js files. If that's the case I think you can probally safely change that line to /*#Import */
Also, I don't know if this was fixed in MVC5 but in MVC4 the minification parser doesn't handle the non-standard :-moz-any() and :-webkit-any() css tags.
Also look at this post that details how to resolve Less #import directories.
We experienced the same issue and it turns out that bootstrap.css is the problem. We were getting the same exact minification errors that you wrote above. The bundler is having problems with #import, #keyframes and #-webkit-keyframes that are in the css file.
What we did to solve the problem is to remove bootstrap.css from the bundle and just reference it directly (or the minified version, if you have it) in the Shared/_Layout.cshtml.
#Styles.Render("~/Content/bootstrap.min.css")
#Styles.Render("~/Content/css")
Minification Problem Solution:
I know Two types of possible that cause optimization problem :
The invalid CSS files that should be validated before bundling. here is W3C CSS validation service to meet this purpose.
Also considering that Microsoft Optimizer reads content of target resources for minification process, so by using some special phrases like # sourceMappingURL=jquery.min.map in a JavaScript file or #charset "UTF-8"; in a styleSheet file, the Minification will be failed again. So try to remove or comment them.
Note that by default, Bundling process can't build relative path of image resources in css or js files.
Relative Image Path Solution:
You can use the same path as bundling path like:
bundles.Add(new StyleBundle("~/Content/css/jquery-ui/bundle")
.Include("~/Content/css/jquery-ui/*.css"));
Where you define the bundle on the same path as the source files that made up the bundle, the relative path of image resources will still work( i.e. /bundle can be any name you like).
Or using new CssRewriteUrlTransform() as second parameter like:
bundles.Add(new StyleBundle("~/Content/css/bundle")
.Include("~/Content/css/*.css", new CssRewriteUrlTransform()));
Encountered this too. I had Bootstrap in the bundle-list among with the main CSS file, in which I imported bootstrap.min.css again. So Bootstrap got requested twice. Removing the import line in my main CSS file solved this for me.
#import don't work with bundle minification.
Do this... in the file BundleConfig.cs set:
bundles.UseCdn = true;
bundles.Add(new StyleBundle("~/skin", "../Content/dark-skin/skin.css"));
And set this in layout:
#Styles.Render("~/skin")
But only application relative URLs (~/url) are allowed.
What I did was, in my BundleConfig.vb (cs), I put all the files I referenced by #import within the css files like this:
bundles.Add(New StyleBundle("~/bundle/css-account") _
.Include("~/Content/consola/bootstrap/css/bootstrap.css",
"~/Content/consola/plugins/node-waves/waves.css",
"~/Content/consola/plugins/animate-css/animate.css", //Referenced by #import
"~/Content/consola/plugins/bootstrap-select/css/bootstrap-select.css",
"~/Content/account/account.css",
"~/fonts/awesome/css/font-awesome.css",//Referenced by #import
"~/Content/consola/materialize.css", //Referenced by #import
"~/Content/consola/style.css"))
That eliminated almost all the errors.
The next thing I did was modify my css files changing css pseudo-classes syntax from this [type="checkbox"]:not(.filled-in, .gm-menu-hamburger) + label:after { to this one [type="checkbox"]:not(.filled-in) + label:after,
[type="checkbox"]:not(.gm-menu-hamburger) + label:after {
That solved all errors I had.
Hope that helps
The issue for me was I had #import in a .css file.
I moved my code into a corresponding .less file that gets compiled on build, which resolved the build error for me. Compiled with Gulp.
Not sure about other, but changes I made in Bundle.config file did not get picked up until I rebuild the project.
I guess, compiler includes the information into the compiled DLL, and no longer looks at Bundle.config.
I am using ASP.NET forms application though, not sure about MVC.
Check if you have any minified (...min.js) files in your bundle.
bundles.Add( ... minified files???
));
Remove them from the bundle and render in the _layout.cshtml file:
#Styles.Render("~/Content/fontawesome-free-5.10.1-web/css/all.min.css")
Or add the non minified version of your css to the bundle.
My solution was the same as #GraehamF, I was having issues where the #imports were trying to load the css, when you inspect with dev tools the bundle css's if you see something like "run-time error", it means the file is not loaded correctly.
Before to deploy remove the debug="true" on your web.config then try to run the code on your local box, that should give you the idea of which files are not getting loaded and causing the bundle did not work.
In my Ruby on Rails project I have some strange problem. I had to switch from sass to less for some reasons. In development all css work is fine. I see my site with right design. But, when I try do some cucumber tests I get error with long trace and it starts from:
Invalid CSS after "bootstrap-theme.css.map */": expected selector or at-rule, was "{"version":3,"s..."
This is not my file, it comes from twitter bootstrap.
Actually, this is json file. Before it come several css files, and all is ok.
Strange that is in development and visual view is good, but in cucumber test I get this error.
It seems your test fails on the CSS sourcemap syntax. Since version 1.5 Less support v3 source map.
When you compile your Less code with source maps, your CSS will end with a reference to sourcemap file, for instance as follows:
/*# sourceMappingURL=bootstrap-theme.css.map */
Notice that the above is valid CSS comment syntax.
And the bootstrap-theme.css.map file has been created. That file indeed contains JSON and not CSS, something like that shown below:
{"version":3,"file":"bootstrap-theme.css","sources":["less/theme.less"
So your tests should not validate *.css.map files as CSS.
