Here is picture in chrome:
I just woder what does user stylesheet mean here. The case is that I am 100% sure that these classes does not exists in my stylesheets (it was before). I thought It comes from cache but it remains even after cache is cleared. Any ideas? Thanks.
First of all, read this definition of what a user style sheet is. It is an extra stylesheet to help you (the user) browse the web. Hence if you prefer certain CSS settings over what the web page designer intended, you can overrule those settings with your own.
This user stylesheet that you found, may therefore just be a local CSS file on your pc.
Therefore we need to know: where did you find that .CSS file?
If the same file is in this location:
PC: C:UsersYourUsernameAppDataLocalGoogleChromeUser DataDefaultUser StyleSheetsCustom.css
MAC: ~/Library/Application Support/Google/Chrome/Default/User StyleSheets/Custom.css
Then the answer is:
The file above is, as it sounds, a CSS file that you can modify and add your own custom styles to, to change the look and feel of your Google Chrome Web Inspector.
Which means that with that specific stylesheet you can change the look of your Google Chrome Web Inspector.
So it has nothing to do with the website you are inspecting, only with how your web inspector looks (it is built with HTML, CSS and JavaScript).
You can read about it here. (Google Chrome version 33 does not feature custom stylesheets)
It could also very well be the case that Google Chrome implements some other user stylesheet that is stored somewhere else on your pc (but I wouldn't know where exactly).
Note that the inspector also shows user agent stylesheets which is the default stylesheet that your browser implements. You can read about those in this question: What is user agent stylesheet
It is possible that the http server itself has cached the previous version of the file and is serving it.
Reload and check the headers in the Network tab, so you can get the full picture. Or if you are using development environment, you can restart the server - just to be sure.

I'm having some issue with a django app and it's CSS file refreshing. Basically I can see that the changes I make in my file are identified and copied in the root folder of my website, however when I open up the web browser that change is not being displayed at all:
I am using Firefox as a browser however this issue happens also on Chromium browser
If you have setup everything well in your settings.py file then your best option is to disable caching form your developer panel.
I had similar issues when I make changes in css and they are not updated when i refresh my browser. This is because the browser is keeping a cache of the css file and its not being updated for some reason.
So according to this post,you can disable caching
I am making a website using PHP. While completing it I tested it on Firefox only. Today when I tried to test it on other browsers (Opera, Chrome & Internet Explorer) I found some problems in my CSS. When I made changes to my CSS file, none of these browsers except Firefox is showing changes made in the CSS file.
<link rel="stylesheet" type="text/css" href="style.css" media="screen">
So far what I have tried after Googling for a long time is
Cleared Cache memory of browser
Put "?v='+1 everytime'" at end of style.css
Refresh the webpage using 'ctrl+f5', 'ctrl+r' etc.
Any help ? Thanks in advance....
This is intended behaviour by most browsers. Whenever you try to load a page, if any resources are already present in browsers' cache, they will be loaded from there.
You have two options:
disable browser cache for your preferred browser (some browsers allow you to disable cache for specific domains)
make your HTML always refresh the resource, by appending a non-repeating parameter to the requested resource file name. I personally use: ?v=1482939287 (where 1482939287 is the timestamp). This will make the browser always refresh the resource, as it will ask for a version that's not existing in browser cache.
Example: <link rel="stylesheet" type="text/css" href="/css/style.css?v=1482939287">
Update: You can flush the cache for a webpage by opening Dev Console (Ctrl+Shift +I), right-click-ing on refresh page arrow (while Dev Console is open) and selecting Empty Cache and Hard Reload. That is emptying the cache.
You can also disable it, as suggested above, by opening Dev Console, going to Network tab and checking "Disable Cache" checkbox right under it. Please note that cache is only disabled while your developer console is open.
There are several solutions for this. I will list you some of my options below.
Unique identifiers to files though parameters
Adding a parameter behind the file as a kind of a version number may help.
In php you can use time() to get the current timestamp or unique() to get a unique string.
Cache settings server side
You can also find some .htaccess settings for caching specific file types on the server side. For performance reasons you should do this for production, too.
Browser Dev Tools
Another way is to open your Browser Dev Tools (mostly F12) while developing. Most browsers like Chrome and FF provides a cacheless enviroment when your Browser Dev Tools are open. As a example in chrome you can disable caching explicit.
My suggestion
Or even better use Task Runner to accomplish this. The keyword to search for is 'cache bust'. As example you can run gulp for concat, versioning, and let it connect the right css files you want to. This is specially suggested for development phase.

Good day.
So, here is my issue.
I'm currently using sharepoint 2010 for web applications, I am supposed to display pdf as part of a web page. Currently, the browser tends to download the pdf file instead of displaying it.
Content-disposition is already set to inline.
I've also used iframe, and src is pointing to custom httpHandler.
I've already added "application/pdf" MIME type in the list of AllowedInlineDownloadedMimeTypes as per the advice in this link http://www.pdfshareforms.com/sharepoint-2010-and-pdf-integration-series-part-1/.
However, the application still failed to display it, and it prompts the user to download the file instead.
I'm using mozilla firefox v12 and ie8 to test the application, they both exhibit the same behavior.
What else is missing? Thank you.
It's important to remember that not all browsers, especially older ones like Internet Explorer 8, have the ability to render PDF content inline. In these older browsers, this was generally accomplished through plug-ins like Adobe Reader or Foxit being installed on the client machine.
Basically, if you are using an older browser, your users will likely need one of these (or a similar) plug-in installed. Otherwise when the browser encounters a PDF file, it will serve it to the user, as it doesn't really know how to deal with it.
There is also a chance that this could be a permissions / settings issue similar to the one addressed in this related question. You may want to review over some of the discussions within that thread as well as this Sharepoint 2010 one, which details a a setting called "Browser File Handling" and how it's default value of "strict" can affect how PDFs and other files are accessed.
He came across the solution while looking at the "Web Application General Settings". There is a setting called Browser File Handling and by default it is set to strict.
I'm hosting an ASP.NET website on Local IIS (not IIS Express), and as soon as I save a change to a .css file in Visual Studio, the change immediately appears in browser windows that use that file (or after mousing over the window in Chrome), without clearing caches and refreshing.
Why do the changes appear immediately?
Opening the .css file itself (not a page using the file) in the browser shows a more expected result: saving the file in Visual Studio does not change what I see in the browser until I refresh the .css file.
As it turns out, I had Browser Link enabled in Visual Studio, and with it, CSS Auto-Sync. This opens up a port on the local machine and uses SignalR to communicate with the browser window about 400 times per second, including any CSS changes needed.
For more information, see these topics:
.net localhost website consistently making get arterySignalR/poll?transport=longPolling&connectionToken= calls
How can I disable __vwd/js/artery in VS.NET 2013?
This probably happens due to caching. when you open the css itself, it retrieves a new copy from the server, but when you open a page that uses the css file, the css file is being cached as the page's resource and the browser just shows the cached resources until you force it to reload them.
a trick i learned to fix the issue, is to link the css file to the aspx page and include a random query string to the linking, that way it tricks the browser to think that its a new resource and reload it from the server anyway.
like this:
<link href="../stylesheets/MyCSS.css?<%=DateTime.Now%>"
rel="stylesheet" type="text/css" />
we use the aspx preprocessor directive <%=DateTime.Now%> to append the current time as a query string, to ensure the link is always different.
Dont forget the question mark between the css filename and the preprocessor directive
I'm developing a Chrome extension that has an options page. And I am willing to style this page same as Chrome options page is styled. I found that there is a file
chrome://resources/css/widgets.css
that holds this style (it is listed in "Developer Tools > Sources"). However, if try to load it in my page either directly from HTML
<link rel="stylesheet" href="chrome://resources/css/widgets.css" type="text/css">
or from CSS
#import url("chrome://resources/css/widgets.css");
then get this error printed in the console:
"Not allowed to load local resource: chrome://resources/css/widgets.css
It looks like I'm missing some permissions in my manifest.json, but did not find anything suitable on the developer's pages (notice it lists "chrome://favicon/", but that's it).
Anyone knows a solution?
P.S. Yes, I have copied this file into my extension's folder, and I got what I want, but the smart and proper way using this file (IMHO) is loading it directly from Chrome resources.
Short answer: No, you can't access chrome://resources... from an extension.
First, it's blocked on purpose, thus why you see "Not allowed to load local resource." Second, you really shouldn't rely on Chrome's resources, which can change in any version.
