CSS stylesheet works hosted locally, but not remote - html

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.

chrome can't use local css for a simple local site

I am having a weird problem.
I am trying to build my github page site. So I am writing my html locally and then push it online to see it.
The problem is that Chrome doesn't recognize my css file when I am opening it locally. When I push the changers online or I am using another browser it work just fine
Here is how I import it on my index.html file:
<html>
<head>
<title>Title</title>
<link rel="stylesheet" type="text/css" href="css/style.css">
</head>
And when I go to the chrome dev tools
css have turned to chinese
Microsoft edge load the css file normally.
I have tried a couple of different things like:
Using another editor
Creating the file in different directory
trying different filenames
Clearing Chromes Cache
Nothing seems to work
I have loaded again a local a site like this and it worked fine.
Any ideas?
Make sure the file encoding is UTF-8. You can use iconv or just in your text editor > save as.

Why is my CSS not working properly in localhost using xampp but working fine when same files are opened locally or from a Netlify site?

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.

Local css file loads, direct address fails

Here is the HTML I am having problems with:
<link rel="stylesheet" href="http://resources.8thdaystudio.com/neonlights.css" type="text/css" />
I have a copy of the css file in my page's local folder, and when I put neonlights.css in the href, it works. I have a copy in my resources server to use from any of my pages, but it's not applying the css when I do the direct link. Using inspect in Chrome it's not showing me an error loading the file but still not applying the css.
it is observed that the url:
http://71.57.185.233:82/neonlights.css loads as text/css
but http://resources.8thdaystudio.com/neonlights.css loads as text/html.
It's due to your server's configuration as you indicated. I have verified this in Fiddler.
Through some reading about MIME types I figured out that the likely problem is my server. I'm running Servers Ultimate Pro on an Android device and I believe it's sending the file with the incorrect type.

CSS file loads when not called

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.

Stylesheet not working in Chrome/Safari but can work in Internet Explorer

TL;DR
I've read through many questions on Stack Overflow on this issue and I've tried to follow the given advice. Still, my CSS stylesheet will not work in Chrome/Safari but it can work in Internet Explorer.
The only odd thing that I can see about my scenario is my server is returning all files as of type application/octet-stream. I cannot change this aspect of the server. Is there something I can do to interpret my CSS file as a stylesheet in Chrome/Safari and IE?
I have an embedded web server project that I am working on. I have very limited control of the server software and the ability to make page-level settings. All I can do is create static HTML, CSS, and image files that are compiled into the server application.
As such, all files that are returned from the embedded server are declared as application/octet-stream in the HTTP header. This produces warnings in Chrome but no errors.
Initially, I had a problem loading this style sheet in Chrome/Safari but it would work in IE. After reading through a couple questions on Stack Overflow, I found that I needed to change my stylesheet declaration from:
<link rel="stylesheet" href="/styles/index.css">
to:
<link rel="stylesheet" type="text/css" href="/styles/index.css">
When I made this change Chrome & Safari still failed to process the CSS file but IE also started to ignore the stylesheet.
Oddly, if I do not declare a DOCTYPE on my HTML document I can get linked stylesheets to work in all of my browsers. This is, however, not a desirable solution.
My guess is this issue has something to do with the HTTP header declaration and that it doesn't match the type declared in the link element.
What can I do to get this stylesheet to work in Chrome, Safari, and IE while following good web development codes-of-practice (i.e. using doctypes on my HTML files and not embedding the style code in the HTML headers?)
For clarity sake, the relevant CSS/HTML code is shown below.
index.css
html {height:100%}
body {margin:0;min-height:100%;position:relative}
iframe {width:100%;height:100%;border:none}
.hdr {min-width:765px;overflow:auto}
.logo1 {float:left;margin:4px}
.logo2 {float:right;margin:4px}
.menu {position:absolute;top:70px;left:0px;bottom:0px;width:175px}
.content {position:absolute;top:70px;left:175px;bottom:0px;right:0px;}
index.htm
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=windows-1252">
<link rel="stylesheet" href="/styles/index.css"> <!-- Removed the type declaration so that this would at least work in IE9 //-->
</head>
<body lang="en-us">
<div class="hdr"><img class="logo1" src="/images/logo1.png" alt="Logo #1"><img class="logo2" src="/images/logo2.png" alt="Logo #2"></div>
<div class="menu"><iframe name="menu" src="/menu.shtm"></iframe></div>
<div class="content"><iframe name="main" src="/home.htm"></iframe></div>
</body>
FYI, this is a new project that is being developed from an existing one. The original project did not declare a DOCTYPE on the HTML files. Therefore, all page data was loaded and executed in the browser in quirks mode. Furthermore, the index.htm originally consisted of multiple frames within a frameset.
I am trying to update this application, using correct, and up to date methods for developing web pages. I can make this application work, but I feel that this would be at a sacrifice of future-browser compatibility if I have to rely on browser quirks mode and framesets.
I have tried to close the link tag but that doesn't help. Technically, this shouldn't be an issue since this document is declared as an HTML5 document, rather than XHTML.
It's certainly due to the application/octet-stream content type. I can re-create the issue on my end. Soon as the content type is set to text/css your HTML/CSS load fine.
As a workaround you can use <style> tags for you CSS if you can't get the server to send the correct content type.
I hate to have to answer my own question this way but the problem was most certainly with the fact that the server was returning a content type of application/octet-stream within the HTTP header.
After discussing the issue with management we had to update the code associated with the HTTP processor. This is code that is part of a third-party RTOS and we have been extremely hesitant to making any changes to this code.
However, in this case the need has out-weighed that desire. I've integrated the necessary changes to fix the HTTP header to return a content type of "text/css" for cascading style sheets. All is now right with the world.
I think I'll just chime in here. Not to answer the question, but to confirm the issue and perhaps help people with similar problems.
I had the same problem: an external css file was loaded alright, but it was not applied in Chrome. (Safari and FF were ok about it). So, same problem, slightly different cause.
It turned out that because of a bug in the webserver code the HTTP response contained two Content Types, 'text/html' and 'text/css'.
The solution was to remove the faulty 'text/html' line. It seems Chrome is pickier than other browsers about response headers. Which I suppose is legitimate, but a warning would have been nice.
btw, you can see all the http information for a loaded resource in Chrome, when you open Developer Tools, and select Network. Then click on the file that you want to investigate. (it took me a while to find that)
We had a problems with an iframe wich it's contents was updated by an external javascript routine, the CSS were loaded but were not applied. But updating the body HTML from a routine present in the iframe head worked as suposed to.
This same behaviour was not present in gecko and explorer, but happened the same at Safari browser (webkit)
Hope this could give some light in this curious case.
I would like to add one bit of information that may save some of you some time. It appeared that chrome was not recognizing my CSS either. After reading the above post I reviewed the files in the Developer Tools->Network. Turns out that Chrome was using a locally cached version of my CSS. As soon as I refreshed as opposed to accessing the URL again, it worked!
I'm no expert, but i've made this mistake before, it's rather simple.
You've written:
<link rel="stylesheet" href="/styles/index.css">
If this is a folder in the same directory as your index.html file, then you need to remove the first /. like so:
<link rel="stylesheet" href="styles/index.css">
EDIT: I think someone else mentioned this already, but it may have been overlooked.
