Currently, I'm using the cdnjs from cloudflare to reference the MarkerCluster plugin js and css files for leaflet, and it works fine. However, when I try and reference the local version I downloaded from the github page and reload my html page, the markerclusters go away. Here are my references:
<link rel="stylesheet" type="text/css" href="Leaflet.markercluster-master/Leaflet.markercluster-master/dist/MarkerCluster.css" />
<link rel="stylesheet" type="text/css" href="Leaflet.markercluster-master/Leaflet.markercluster-master/dist/MarkerCluster.Default.css" />
<script src="Leaflet.markercluster-master/Leaflet.markercluster-master/src/MarkerCluster.js"></script>
I have checked and rechecked the file paths and I can confirm they are correct. I've referenced both MarkerCluster.css and MarkerCluster.Default.css because that was recommended when I reference through cdnjs. I've made sure to redownload the latest version from github, still to no avail.
I've added and deleted type="text/javascript" from the script that runs the js file, but that didn't help either:
<script type="text/javascript" src="Leaflet.markercluster-master/Leaflet.markercluster-master/src/MarkerCluster.js"></script>
I am referencing these files within the <head> of the html file. Any help would be greatly appreciated!
Reasoning:
I would like to reference the local files so that it can act as a backup in case the cdnjs goes down. I know that this has very rarely happened, if ever. But for this project, we are concerned with maintaining this site for a long time and want to ensure the maximum amount of protection against plugins breaking/becoming incompatible.
The MarkerCluster.js file you have downloaded is just a part of the source code of the plugin.
It is concatenated with other source files to produce the dist file that is available on public CDN's.
See the disclaimer on the repository: https://github.com/Leaflet/Leaflet.markercluster/blob/master/dist/WhereAreTheJavascriptFiles.txt
We don't ship the .js files in the git master branch.
They are only present in version tags and in npm.
See how to get the JS files here: https://github.com/Leaflet/Leaflet.markercluster#using-the-plugin
Or how to build them: https://github.com/Leaflet/Leaflet.markercluster#building-testing-and-linting-scripts
A very simple mean to retrieve this dist JS file is to download what you get from the CDN. E.g. paste the URL in your browser address bar; this should display the raw content of the file. Then right click anywhere on the code and select "Save as..."
If you look in dist/WhereAreTheJavascriptFiles.txt you'll see that if you download the source you need to build the dist js files with jake. Or just use the CDN. The js file you've included is part of the source codebase.
I'm working on a website that uses Gulp.js to compile and browser sync to keep the browser synchronised with my changes.
The Gulp.js task compiles everything properly, but on the website, I'm unable to see any style, and the console shows this error message:
Refused to apply style from
'http://localhost:3000/assets/styles/custom-style.css' because its
MIME type ('text/html') is not a supported stylesheet MIME type, and
strict MIME checking is enabled.
Now, I don't really understand why this happens.
The HTML includes the file like this (which I am pretty sure is correct):
<link rel="stylesheet" type="text/css" href="assets/styles/custom-style.css"/>
And the style sheet is a merge between Bootstrap and Font Awesome styles for now (nothing custom yet).
The path is correct as well, as this is the folder structure:
index.html
assets
|-styles
|-custom-style.css
But I keep getting the error.
What could it be? Is this something (maybe a setting?) for gulp/browsersync maybe?
For Node.js applications, check your configuration:
app.use(express.static(__dirname + '/public'));
Notice that /public does not have a forward slash at the end, so you will need to include it in your href option of your HTML:
href="/css/style.css">
If you did include a forward slash (/public/) then you can just do href="css/style.css".
The issue, I think, was with a CSS library starting with comments.
While in development, I do not minify files and I don't remove comments. This meant that the stylesheet started with some comments, causing it to be seen as something different from CSS.
Removing the library and putting it into a vendor file (which is ALWAYS minified without comments) solved the issue.
Again, I'm not 100% sure this is a fix, but it's still a win for me as it works as expected now.
In most cases, this could be simply the CSS file path is wrong. So the web server returns status: 404 with some Not Found content payload of html type.
The browser follows this (wrong) path from <link rel="stylesheet" ...> tag with the intention of applying CSS styles. But the returned content type contradicts so that it logs an error.
This error can also come up when you're not referring to your CSS file properly.
For example, if your link tag is
<link rel="stylesheet" href="styles.css">
but your CSS file is named style.css (without the second s) then there is a good chance that you will see this error.
I had this error for a Bootstrap template.
<link href="starter-template.css" rel="stylesheet">
Then I removed the rel="stylesheet" from the link, i.e.:
<link href="starter-template.css">
And everything works fine. Try this if you are using Bootstrap templates.
I have changed my href to src. So from this:
<link rel="stylesheet" href="dist/photoswipe.css">
to this:
<link rel="stylesheet" src="dist/photoswipe.css">
It worked. I don't know why, but it did the job.
Make a folder just below/above the style.css file as per the Angular structure and provide a link like <link href="vendor/bootstrap/css/bootstrap.min.css" rel="stylesheet">.
Comments in your file will trip this. Some minifiers will not remove comments.
Also
If you use Node.js and set your static files using express such as:
app.use(express.static(__dirname + '/public'));
You need to properly address the files.
In my case both were the issue, so I prefixed my CSS links with "/css/styles.css".
Example:
<link type="text/css" rel="stylesheet" href='/css/styles.css">
This solution is perfect as the path is the main issue for CSS not getting rendering
In addition to using:
<base href="/">
Remove the rel="stylesheet" part from your CSS links:
<link type="text/css" href="assets/styles/custom-style.css"/>
I simply referenced the CSS file (an Angular theme in my case) in the styles section of my Angular 6 build configuration in angular.json:
This does not answer the question, but it might be a suitable workaround, as it was for me.
I know it might be out of context but linking a non existed file might cause this issue as it happened to me before.
<!-- bootstrap grid -->
<link rel="stylesheet" href="./css/bootstrap-grid.css" />
If this file does not exist you will face that issue.
The problem is that if you have a relative path, and you navigate to a nested page, that would resolve to the wrong path:
<link rel="stylesheet" href='./index.css'>
so the simple solution was to remove the . since mine is a single-page application.
Like this:
<link rel="stylesheet" href='/index.css'>
so it always resolves to /index.css
There are a lot of answers to this question but none of them seem to really work. If you remove rel="stylesheet" it will stop the errors but won't apply the stylesheets.
The real solution:
Just remove the .. It works then.
As mentioned solutions in this post, some of the solutions worked for me, but CSS does not apply on the page.
Simply, I just moved the "css" directory into the "Assest/" directory and everything works fine.
<link rel="stylesheet" type="text/css" href="assets/css/bootstrap.css">
<link rel="stylesheet" type="text/css" href="assets/css/site.css" >
I got the same issue and then I checked that I wrote:
<base href="./"> in index.html
Then I changed to
<base href="/">
And then it worked fine.
Also for others using Angular-CLI and publishing to a sub-folder on the webserver, check this answer:
When you're deploying to a non-root path within a domain, you'll need to manually update the <base href="/"> tag in your dist/index.html.
In this case, you will need to update to <base href="/sub-folder/">

I had this problem with a site I knew worked online when I moved it to localhost and PhpStorm.
This worked fine online:
<link rel="stylesheet" href="/css/additional.css">
But for localhost I needed to get rid of the slash:
<link rel="stylesheet" href="css/additional.css">
So I am reinforcing a few answers provided here already - it is likely to be a path or spelling mistake rather than any complicated server setup problem. The error in the console is a red herring; the network tab needs to be checked for the 404 first.
Among the answers provided here are a few solutions that are not correct. The addition of type="text/html" or changing href to src is not the answer.
If you want to have all of the attributes so it validates on the pickiest of validators and your IDE then the media value should be provided and the rel should be stylesheet, e.g.:
<link rel="stylesheet" href="css/additional.css" type="text/css" media="all">
I have had the same problem.
If your project's structure is like the following tree:
index.html
assets
|-styles
|-custom-style.css
server
|- server.js
I recommend to add the following piece of code in server.js:
var path = require('path')
var express = require('express')
var app = express()
app.use('/assets', express.static(path.join(__dirname, "../assets")));
Note: Path is a built-in Node.js module, so it doesn't need to install this package via npm.
You can open the Google Chrome tools, select the network tab, reload your page and find the file request of the CSS and look for what it have inside the file.
Maybe you did something wrong when you merged the two libraries in your file, including some characters or headers not properly for CSS?
At times, this happens when the CSS file is not found. It's worth checking your base URL / path to the file.
Adding to a long list of answers, this issue also happened to me because I did not realize the path was wrong from a browser-sync point of view.
Given this simple folder structure:
package.json
app
|-index.html
|-styles
|-style.css
The href attribute inside <link> in file index.html has to be app/styles/style.css and not styles/style.css.
In case you are using Express.js without any JavaScript code, try with:
app.use(express.static('public'));
As an example, my CSS file is at public/stylesheets/app.css.
How I solved this.
For Node.js applications, you need to set your **public** folder configuration.
// Express js
app.use(express.static(__dirname + '/public'));
Otherwise, you need to do like href="public/css/style.css".
<link href="public/assets/css/custom.css">
<script src="public/assets/js/scripts.js"></script>
Note: It will work for http://localhost:3000/public/assets/css/custom.css. But couldn't work after build. You need to set app.use(express.static(__dirname + '/public')); for Express
For a Node.js application, just use this after importing all the required modules in your server file:
app.use(express.static("."));
express.static built-in middleware function in Express and this in your .html file: <link rel="stylesheet" href="style.css">
By going into my browsers console → Network → style.css ...clicked on it and it showed "cannot get /path/to/my/CSS", this told me my link was wrong.
I changed that to the path of my CSS file.
The original path before change was localhost:3000/Example/public/style.css. Changing it to localhost:3000/style.css solved it.
If you are serving the file from app.use(express.static(path.join(__dirname, "public"))); or app.use(express.static("public")); your server would pass "that folder" to the browser so adding a "/yourCssName.css" link in your browser solves it
By adding other routes in your browser CSS link, you'd be telling the browser to search for the css in route specified.
In summary: Check where your browser CSS link points to.
This is specific to TypeScript and Express.js
I Ctrl + F'd "TypeScript" and ".ts" and found nothing in these answers, so I'll add my solution here, since it was caused by (my inexperience with) TypeScript, and the solutions I've read don't explicit solve this particular issue.
The problem was that TypeScript was compiling my app.ts file into a JavaScript file in my project's dist directory, dist/app.js.
Here's my directory structure. See if you can spot the problem:
.
├── app.ts
├── dist
│ ├── app.js
│ ├── app.js.map
│ └── js
│ ├── dbclient.js
│ ├── dbclient.js.map
│ ├── mutators.js
│ └── mutators.js.map
├── public
│ ├── css
│ │ └── styles.css
├── tsconfig.json
├── tslint.json
└── views
├── index.hbs
└── results.hbs
My problem is that in app.ts, I was telling express to set my public directory as /public, which would be a valid path if Node.js actually were running TypeScript. But Node.js is running the compiled JavaScript, app.js, which is in the dist directory.
So having app.ts pretend it's dist/app.js solved my problem. Thus, I fixed the problem in app.ts by changing
app.use(e.static(path.join(__dirname, "/public")));
to
app.use(e.static(path.join(__dirname, "../public")));

Found the above solution of adding
href="/">
Just before the style tag in index.html
I was working with the React application and also had this error which led me here. This is what helped me.
Instead of adding <link> to the index.html, I added an import to the component where I need to use this style sheet:
import 'path/to/stylesheet.css';
In my case, when I was deploying the package live, I had it out of the public HTML folder. It was for a reason.
But apparently a strict MIME type check has been activated, and I am not too sure if it's on my side or by the company I am hosting with.
But as soon as I moved the styling folder in the same directory as the index.php file I stopped getting the error, and styling was activated perfectly.
Bootstrap styles not loading #3411
https://github.com/angular/angular-cli/issues/3411
I installed Bootstrap v. 3.3.7
npm install bootstrap --save
Then I added the needed script files to apps[0].scripts in the angular-cli.json file:
"scripts": [
"../node_modules/bootstrap/dist/js/bootstrap.js"
],
// And the Bootstrap CSS to the apps[0].styles array
"styles": [
"styles.css",
"../node_modules/bootstrap/dist/css/bootstrap.css"
],
I restarted ng serve
It worked for me.
If you are setting Styles in JavaScript as:
var cssLink = document.createElement("link");
cssLink.href = "./content.component.scss";
cssLink.rel = "stylesheet";
/* → */ cssLink.type = "html/css";
(iframe as HTMLIFrameElement).contentDocument.head.appendChild(cssLink);
Then just change field cssLint.type (denoted by the arrow in the above description) to "MIME":
cssLink.type = "MIME";
It will help you to get rid of the error.
