I noticed recently that something is related to CSS3 and some DOM elements that kind of make ::before and ::after appear in the inspector window. I wonder why they appear there?
The sample is as follows:
Get a Local Copy of Bootstrap
If you can't access Bootstrap from the CDN, you'll need to pull it in via NuGet or your preferred package manager (npm, bower, etc.). This will download the files into your solution so that they don't require any external connections.
Additionally, you can download Bootstrap directly if you would prefer that approach.
Reference the Local File
Once you have it in your solution, you'll just need to reference it by location within the <head> section of your _Layout.cshtml file:
<!-- Point to the location within your solution that Bootstrap is stored -->
<link href="~/Content/bootstrap.min.css" rel="stylesheet" type="text/css" />
Or you can simply drag-drop it from your Solution Explorer :
If you are still encountering issues, consider checking the Developer Tools (F12) within your browser and clearing your cache to ensure the latest files are being pulled properly.

I have a simple, local HTML file:
<html>
<head>
<link href="stylesheet.css" rel="stylesheet" type="text/css"/>
</head>
<body>
<div class="myclass">Hello World</div>
</body>
</html>
and a simple stylesheet:
.myclass {
color: #456123;
background-color: red;
}
I am deploying my stylesheet to an outside cloud hosting service (AWS S3). However, when I swap the URL out, the styles don't work anymore:
<link href="https://example.s3.us-east-2.amazonaws.com/stylesheet.css" rel="stylesheet" type="text/css"/>
What do I mean by they don't work? The page doesn't display correctly, none of my styles get applied. The page renders as if there was no stylesheet at all.
I've tested all the obvious things, and then some:
The remote stylesheet is accessible, I downloaded it separately by URL and WGet
The remote stylesheet is the exact same as local, byte-for-byte (no diff)
I have disabled cache in my browser
I have hard refreshed
Per my browser tools > network tab, the browser loads the stylesheet promptly (~200ms)
Per my browser tools > sources tab, I can confirm that the entire stylesheet is there, present as a source and readable
I even wrote a script that I loaded into the body that fetched the CSS stylesheet externally, and using a callback after that, created the myclass div. The styles still didn't apply, even when controlling for latency/race conditions like that.
What could be going on here?
Fixed it! I found a similar problem here, which led me to the answer: when CSS files get uploaded to AWS, they get uploaded as Content-Type: Binary/Octet-Stream for some godforsaken reason. (Madness!)
My browser tools didn't raise that as an issue -- I guess browsers are pretty flexible these days -- but it must've still been an issue for HTML rendering.
So the solution is simple: go into AWS S3, click on the file, and change its metadata to hold:Content-Type: text/css. Or you can also set that metadata programmatically if you're uploading these files via an AWS CLI or SDK.
As an aside, you should do the same for JS files, which also get uploaded as binary/octet-stream. For whatever reason, the browser is still able to execute those fine.
I have a very strange problem that never happen to me. I normally attach css as always and in Visual Studio code or in local file is working perfect. <link href="css/style.css" rel="stylesheet">
But when I host page all css is gone(I try 4 of them). Then I must reload all linked stylesheet to be working again(special extension in chrome). Someone have any idea why this happen?
Edit: As the user suggest, also first try to clear the browser cache, deleting cookies and data, before continuing troubleshooting.
The most common problem causing that issue is the location of the .css file, it depends on how you are hosting the site but perhaps setting an absolute path to the file can help you discard the location issue. Also you are telling something about a chrome extension, did you try loading the page in another browser for troubleshooting?
Useful information: To avoid the problem of caching styles and scripts, it is recommended to use version
<link rel="stylesheet" href="/mydomain.com/css/style?v=1598035492054">

So I've been working on a website for college and I'm starting to learn PHP but for that I installed xampp and tried to access the website from localhost.
By my understanding, the HTML file and images, even (some) images defined in CSS are loading but the entire CSS file is not, like float and flexbox and some padding, borders, and different types of positioning isn't working as intended. It's definitely finding the CSS file so I don't think there's a problem in my <link> tag in the <header>.
HTML header:
<head>
<meta charset="utf-8">
<title>Home - akiro</title>
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<link href="https://fonts.googleapis.com/css?family=Oswald&display=swap" rel="stylesheet">
<link href="https://fonts.googleapis.com/css?family=Merriweather&display=swap" rel="stylesheet">
<link rel="stylesheet" href="style.css" type="text/css">
</head>
As Doc-Han Stated this is most likely caching, and its an issue I think most of us have run into during the UI development process.
One thing you can do to get around this, is to open and do your debugging in an incognito window which wont cache files and can be reopened to load new sets if session caching does occur.
Alternatively some code editors have an in-built web server instead for this reason. I've been using Adobe brackets for a couple years now and love it. It serves the pages using an internal Node server and as a result, they have it set up for real time code updates. Changes to the code are reflected in real time which i find helps a lot in dealing with UI development flow for me avoiding issues like this and just the saved 3-5 seconds of refreshing each time i make a change (which adds up when your making 5000 changes Im certain other editors offer something like this as well.
This is just because with Xampp the browser caches your CSS files. This means that if making changes to the file, the browser will still access the cached file rather than the new one. A simple trick is to open the CSS from the local server and refresh the page so that the new CSS will be used.
example open localhost:8080/project/css/style.css and refresh that page
Quite some possibilities why it's not working as expected:
As Doc-Han stated; an old version of the css my have been cached.
You're loading the css from a relative path: style.css. This means the css should be in the same folder as the html file. Maybe the css should be loaded from '/style.css' or '/resources/style.css' or another location
Maybe the css contains some simple typo's so you're applying 'flaot' instead of 'float'
Inspect your page through your browsers developer tools. Open the console. Check if there are there any errors. Check if the css did load, also check if the right version was loaded. Check if the styling rules are applied to the right html elements or are applied at all.
If it is a caching problem in Chrome you can open the dev tools, open the Application tab, click the 'clear storage' menu item and clear site data. Now reload the page. In the network tab you can also click 'disable cache' and reload the page.
Just clear your browser's caches and done!
I just had the same problem but opposite and troubleshooting with Google brought me here.
My server was working perfectly in localhost but when I tried visiting it live via Ngrok or port forwarding, I got broken pages without CSS. I read a comment in this post about visiting the CSS file directly and then refreshing and in doing so realized I couldn't visit a lot of my CSS files, and then realized I set rules in my .htaccess for rewriting. Only leaving this comment so if anyone makes my mistake and finds themselves here like I found myself here, check your .htaccess.
I'm trying to use Font-Awesome icon fonts via the BootstrapCDN link which I'm pretty sure I have the latest version of:
<link href="//netdna.bootstrapcdn.com/font-awesome/4.0.3/css/font-awesome.css" rel="stylesheet">
I've put this link in the <head> part of my html file and I am trying to get it to work with this simple html code of:
<!DOCTYPE html>
<html>
<head>
<title>Font-Awesome Icons</title>
<link href="//netdna.bootstrapcdn.com/font-awesome/4.0.3/css/font-awesome.css" rel="stylesheet">
</head>
<body>
<p><i class="fa fa-camera-retro"></i> Camera Icon<i class="fa fa-facebook"></i> Facebook Icon</p>
</body>
</html>
However it's not rendering. I've tried this code in the latest versions of FireFox (27), Safari(7) and Chrome(33). I've checked that the fa class is on each of the icons I'm trying to call up and also that the fa- prefix is being used as opposed to the old icon- prefix. I've checked my implementation of the code with this video http://headwaythemes.com/using-font-awesome-with-headway/ (although meant for a WordPress theme, in principal the code should work the same) and looked around on stack overflow but previous questions like Fontawesome not loading haven't yielded me any help in solving my issue.
I don't have the fontawesome.otf installed but surely it isn't that if I can see the glyphs when visiting http://fortawesome.github.io.
Should I just download and host the font-awesome files along with my entire future website so I don't have to worry about updating the BoostrapCDN link as well? - Even though I only plan to use a few icons?
The reason it is not loading is because the URI is starting with "//". That signifies that it is a protocol relative path, meaning it will use whatever protocol that page is using. If you open your html locally, then your browser will use file as the protocol, thus trying to access the font-awesome css with "file://". If you access your html using a local or remote http web server, then you would access the page using the http protocol, thus accessing the css with "http://".
Solution:
Change the path of the css or mimic it on your local machine.
Run a local or remote http server and access the page.
For more info:
URI starting with two slashes ... how do they behave?
Such an easier way to deal with this - just add 'http:' in front for the cdn line, and it will work on your local machine, i.e. like this:
<link href="http://maxcdn.bootstrapcdn.com/font-awesome/4.2.0/css/font-awesome.min.css" rel="stylesheet">
Ta-daa!
What Pulkit answered is absolutely correct. Just to add, if you want to create a quick local server, just go to the directory of the html and css pages, and then go to the terminal and type -
$python -m SimpleHTTPServer
Then, go to your browser and go to 127.0.0.1:8000
If it doesn't show up, try changing the homepage of your website to index.html
Hi I have a question about the loading of CSS files.
I know there is only 3 ways to add style to your elements, but technically only 1 way to add a CSS file to a HTML document.
<head>
<link rel="stylesheet" type="text/css" href="mystyle.css">
</head>
I have a problem here though. I have a CSS file loaded that was not listed to be loaded for that area/HTML file. Even more strange, My colleague and I have the EXACT same revision on the software, the exact same data file... everything is exact except the google chrome version. But when he loads it up, the CSS file is not loaded for him and its perfect on all other machines as-well.
If there is no command to load that file, can it get stuck in the cache and be loaded for "child" forms?
This file is used on the login screen for styling and its the only place. The main site in completely separate..... yet not
Any idea will be appreciated.
If you colleague has the same code as you, and it's is not loading for him then it's probably cached in the browser. You can clear out your cache in Chrome by pressing ctrl + shift + delete and select empty the cache.
