import of css from top level css is blocked - css

Inside a web page I have the following snippet:
<html>
<head>
<META http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
<base href="https://XXXXX /">
<title>Example</title>
<link href="Layout/standard.css" type="text/css" title="Example" rel="stylesheet">
</head>
<body>
The referenced page standard.css looks like this:
#import url( "standard2.css" );
#import url( "standard3.css" );
After upgrading the noscript plugin (version 2.4.3) within Firfefox ESR 10.0.4 the css pages standard2.css and standard3.css are not loaded anymore. With an earlier version of noscript everything worked as expected.
Why is noscript blocking this? Is there a known security problem importing a css from within another css? Or is it simply a bug in noscript?
Update: The problem is not the cascaded import. The problem is that I used a short URL (https://hostname/...). If I use a fully qualified URL (https://hostname.mynet.com/...) everything is working.
So it really looks like a bug in noscript 2.4.3.

The NoScript changelog doesn't mention any changes to this, so it's probably a bug.

I wrote two other pages in this project correctly. But, when intended to code the third one, changes didn't apply at all.it seems that my html code doesn't receive the styles.
Surprisingly, the sass file fully converted to CSS file, and no problem was evident.
SASS / SCSS is a preprocessor for CSS, and can't be interpreted by your browser.
This is a duplicate question and possible solutions have alredy been described here: Attaching a SCSS to HTML docs
if you are using vs code download a sass extension which will convert your sass code into a css code and then you can link that css file generated by the extension to your html page
i will recommend scss-to-css extension by yutent as it doesn't require you to make it active like other extensions
you must read documentation sass official and follow this guide https://sass-lang.com/guide. if you not install sass this two way how install sass
read this https://sass-lang.com/install
or download extension in visual code
if you are still confused change your sass become sport.css

reactjs navbar design proglem(using bootstrap css internally)

I have a problem with the navigation bar,
I have a navigation bar for my project. As you can see my code below if I use the link and get it from an external source it is working well. But there is a problem for me when the net is a bit slow I can see the navigation's loading on my screen. it is a very small duration but it disturbs me very much. So I decided to use CSS source from my project folder but could not do that. I tried many code samples but could not do it correctly. If somebody helps me, I will appreciate it. Thanks.
I am also still trying to solve it but I wanted to get some help.
function MyNavBar(params) {
//console.log(params["conpanyID"]);

you might have linked your stylesheet inside the body instead of the header section , because of which your page will load first, then your CSS
here is an example
<!DOCTYPE html>
<html lang="en" dir="ltr">

<meta charset="utf-8">
<title>file</title>
<link rel="stylesheet" href="css/s.css">

Font Awesome class "fa-check" is not displaying check mark

I have a simple html page using font awesome css. Can anyone see why my font awesome check mark is not displaying, I cannot get the check mark to display and I cannot seem to figure out why.
I am using the .min.css link in my <Head> as such:
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<meta http-equiv="X-UA-Compatible" content="ie=edge">
<title>LoopLAB Theme</title>
<link rel="stylesheet" href="css/font-awesome.min.css">
<link rel="stylesheet" href="css/bootstrap.css">
<link rel="stylesheet" href="css/style.css">
</head>
When I want to inject it into a <i> element in the DOM, I simply use this:
<i class="fa fa-check"></i>
As you can see above, the check mark does not display. Do you see anything obvious that I am doing wrong? This seems like a beginner's error but I can't find the problem.
Check your CSS. There are a few ways you can do that!
Simply check if font-awesome.min.css is indeed under your CSS folder. If it is, check your folder structure. Can your HTML access this folder using css/font-awesome.min.css? The CSS folder must be a child from the folder you are currently storing your HTML file. Finally, are you using the latest version of font-awesome-min.css? This specific icon might not be included in your CSS file if it's an older version.
Inspect your site using your favorite browser inspect tool and locate your CSS file on inside the inspector. Clicking on it should open your CSS code. The code should be minified. If there is nothing inside of it or some kind of error your website is failing to find your file on your server or computer.
Plus you can also add from a CDN, for example, https://maxcdn.bootstrapcdn.com/font-awesome/4.7.0/css/font-awesome.min.css and import directly to your code.

I renamed my css file and now it doesn't work

Doing a website for a client and I merely changed the name of the css file in the folder and in the references on each page. And suddenly all my styling is gone. I've checked multiple times for spelling errors and it's all correct and I do believe I have referenced it correctly as it was working previously under a different name. My Question is How can the changing of the css file suddenly stop it working if it's still referenced correctly? Could it be that bootstrap is overriding it somehow?

Here is the <head> for my index html file.
The problem only occurred when I changed the file names but I can't leave it as "TestLayout" when it is a completed project. Any help is appreciated and I can supply what I can to help find the solution. Thanks in advance.
First off, a small tip: Load your custom CSS-file AFTER the bootstrap.css file. This way you can ensure that your styles are easily overriding the defaults of Bootstrap, so you don't have to bash in !important in order to change something.
And for your question, have you accidentally removed css/ from the beginning of your style.css? Since all the other CSS styles you have linked are under the CSS-folder.
Double check that, otherwise it should work, the name is valid.
If the path to your CSS file is still correct (and you haven't inadvertently removed the folder from the file path as per ProDexorite's answer) then you might need to completely refresh your browser.
You can do this with CTRL+F5 or to be completely sure you can empty your browser cache, although I usually find this isn't necessary.
ProDexorite is also correct regarding the CSS files - it's called Cascading Style Script which means any styles in the files you load last will overwrite the files loaded before. Therefore any custom CSS (main.css and style.css for example) should be loaded AFTER the Bootstrap or any other library css files. This just means you need to reference them in the right order in your page that's all.

Flash of unstyled content (FOUC) in Firefox only? Is FF slow renderer?

I'm not seeing this issue in any other browser that I've tested - IE, Chrome, Opera - but whenever I load a page from the server, I'm seeing a flash of unstyled content before the CSS is applied.
This is even happening on subsequent page loads where everything should be cached - every time the page loads I see the unstyled content for a split-second, then everything settles in.
It's also worth noting (perhaps?) that the page is using #font-face to pull some Google fonts. They are stored in a separate stylesheet being pulled after the main responsive stylesheets and media queries.
I've tried a few different things, to no effect:
Rearranging order of CSS stylesheet links
Removing link to stylesheets with #font-face
Disabling Firebug? (Read on here somewhere...)
One other thing that may be worth mentioning is that I used quite a lot of Element Type CSS selectors in the page's CSS. Is it possible that this is slowing down the rendering process?
This seems unlikely as there is no problem immediately re-rendering the page upon changing the dimensions of the window - the responsive stuff renders fine immediately.
So this leads me to believe that there is some issue with how the CSS is being loaded.
Here is my HEAD code:
<!DOCTYPE html>
<head>
<!--<meta name="robots" content="noindex" />-->
<meta charset="utf-8">
<meta name="description" content="">
<meta name="viewport" content="width=device-width; initial-scale=1.0; maximum-scale=1.0; minimum-scale=1.0; user-scalable=no; target-densityDpi=device-dpi" />

WTF is going wrong with Firefox? It's driving me nuts!
If you add a dummy <script> tag right after <body>, Firefox will show the page after all the css from <head> is loaded:
<body>
<script>0</script>
<!-- rest of the code -->
</body>
There is an official bugreport about this FOUC (Flash Of Unstyled Content) on the Firefox site: https://bugzilla.mozilla.org/show_bug.cgi?id=1404468
I had the same problem with Layout was forced before the page was fully loaded. If stylesheets are not yet loaded this may cause a flash of unstyled content. showing in the console, and a visible flash of unstyled content upon page refresh, withouth (F5) or with clearing the cache (Ctrl + F5). Having the developer tools open does not made a difference either.
What helped me was declaring a variable in a script just before the </head> tag ended, so basically after all the <link> tags.
It's important to note, that an empty script (or with just a comment) or any random javaScript would not help, but declaring a variable worked.
<head>
<link rel="stylesheet" href="css/main.css" />
<link rel="stylesheet" href="css/other.css" />
<script>
/*to prevent Firefox FOUC, this must be here*/
let FF_FOUC_FIX;
</script>
</head>
There was no need to rearrange links or not use imports within css or js files.
Please note that the issue will no longer be visible (FOUC is visibly gone), but the console might still show the same warning.
I was experiencing this error. A colleague has said that it's caused by the attribute, autofocus being added to a form field.
By removing this attribute and using JavaScript to set the focus the brief flash of unstyled content stops happening.
For what it's worth, I had this same problem and found that it was being caused by having poorly formatted <html>...</html> tags.
To be precise, in my code I accidentally closed the HTML tag too early, like this:
<!DOCTYPE html>
<html lang="en"></html>
<head>
<title>My title</title>
The code provided by the original poster is missing the opening <html> so I suspect that's probably what is happening there.
Filament Group share they way they load their fonts in detail,
http://www.filamentgroup.com/lab/font-loading.html
which is a nice modern approach to #font-face loading
Smashing magazine also review there website performance and came up with a different solution that stores the caches a base64 copy of the font in local storage. This solution may require a different licence for you font.

Additional recommendation
The head of your document contains far to many individual stylesheets, all these css files should be combined into a single file, minified and gziped. You may have a second link for your fonts placed before you main stylesheet.
<link rel="stylesheet" href="resources/css/fonts.css" type="text/css" />
<link rel="stylesheet" href="resources/css/main.css" type="text/css" />
I've had the same issue. In my case removing #import rule in the CSS file and linking all the CSS files in the HTML resolved it.
In my case the reason of FOUC in FF was the presence of iframe on page.
If I removing iframe from markup then FOUC disappears.
But I need iframe for my own hacking reasons so I changed this
<iframe name="hidden-iframe" style="display: none;position:absolute;"></iframe>
into this
<script>
document.addEventListener('DOMContentLoaded', ()=>{
let nBody = document.querySelector('body')
let nIframe = document.createElement('iframe');
nIframe.setAttribute('name', "hidden-iframe");
nIframe.style.display = 'none';
nIframe.style.position = 'absolute';
nBody.appendChild(nIframe);
});
</script>
I've added this inline JS right in template just for readability: in my case this code runs once per page.
I know that it's dirty hack, so you can add this code in separated JS-file.
The problem was in Firefox Quantum v65.
I had the same problem (but also in chrome). Even if many of the existing answers provide clues to the reason for FOUC I wanted to present my problem and its solution.
As I said, I had FOUC in a fairly large project and already had the suspicion of a racecondition in some form.
In the project SASS is used and via a "bootstrap" file for the css a fontawesome free package was added via import.
#import "#fortawesome/fontawesome-free/css/all.css";
This import has increased the total size of the css file by a lot, which caused the file to take a long time to load, and the browser went and already loaded the following javascript.
The JS that was then executed forced the rendering of its content and thus created the FOUC.
So the solution in my case was to remove the big fontawesome package and insert the icons I used from it (~10) via an Icomoon custom font. Not only did this solve the FOUC but it also had the nice side effect that the delivered CSS files are much smaller.
