For some reason I can't get the new css to be used in firefox or ie's browser.
I am using php to consolidate all the css into one file, then output it like so:
PHP file:
header('Content-type: text/css');
readfile('layout.css');
readfile('a.css'); //jqueryUI
Here's how I call it from the HTML side:
<link rel='stylesheet' href='stylesheet/css.php?v=1327523109' type='text/css' />
The "v" querystring parameter is simply a php time() function from a tip I got on another search for the problem. Hoping the time() would trick the browser into not loading the cache version, but it is not working and still loading the old css.
When I look in firebug's css file it shows the old css file. However if I directly access the .css page through the url, the output to the browser screen shows all the new css code.
if I render the same page in the chrome browser it shows the new css without any problem...but ie and ff show the old css.
I don't understand what's going on and how to fix it. Can anyone help me?
ctrl + shift + del In both browser will allow you to clear your cache, cookies, temp files, and more via nice checkboxes.
Perhaps the css file is cached in the browser. Try CTRL+F5. If that doesn't work try clearing the cache, if that doesn't work try a reboot. :D
I tried CTRL+F5, Clearing the cache, rebooting...none of that worked right. Then I decided to change the ordering inside the css.php file for the readfile() functions. Once I moved the ordering around it triggered the new css to load. I don't know exactly why this worked, but now the new css loaded.
Decided to answer this here in case someone else comes accross a similar problem and the traditional cache clearing doesn't fix it.
Here is the trick, instead version, just use the PHP filemtime() Function to show your last modified file.
<link rel='stylesheet' href='stylesheet/css.php?<?php filemtime('stylesheet/css.php'?>' type='text/css' />
So every time you modified CSS file, the browser will know what file must be loaded.
hope it help..

My site is in a Host. (Not localhost)
Framework: CodeIgniter.
Changes made using CSS: Flot chart's legend
I did changes to front end using Chrome tools/developer tools.
I can see all the changes I made instantly.
I FTP to the site, downloaded the CSS file, did necessary changes (same as chrome developer changers) and uploaded the CCS file.
I access the site, but I cannot see the changes I made using CSS file.
Check if your hosted CSS contains the latest changes
If CSS is ok try to open chrome dev tools and inspect the element that you are trying to modify. Scroll through the CSS applied to that element and check if your styles are there.
If you didn't find any of the styles that you are tring to apply to the element probably you misspelled the selector name. Remember to check .class #id
also, in order to ensure that your CSS files are not cached suffix your php files like this
<link href="/stylesheet.css?<?php echo time(); ?>" rel="stylesheet" type="text/css" /&glt;
EDIT
tip above also works for any resource! (css, javascript files, images ...)
Try Ctrl+F5. It's hard refresh
change the name of the css file so there are no cache issues and then check. if that does not work then look at your source code and copy paste the address of the css file to make absolutely certain you have the link correct.
I think your CSS is still cached so have a Look at this popular question: How to force browser to reload cached CSS/JS files?
There are some solutions how you can force your browser to refresh the CSS or js.
The easiest answer you will get is using something like this:
/styles/screen.css?v=1234
If you did a change all you have to do is to +1 the counter!
In PHP you van also use this:
<link rel="stylesheet" href="mycss.css?v=<?php echo filemtime('mycss.css') ?>"/>
It's like an autocounter using the timestamp of the CSS file.
In the DevTools Settings (F1) or in the Network panel (depends on what version of Chrome you are using) tick the Disable cache (while DevTools is open) checkbox. If caching is your problem, it should get fixed.
This is such an annoying and timeconsuming bug!
Since a while back I have to clear the cookies each time I change something in my .css file. Well, currently it's a .less file. But this has happened to me before and also my buddy when working with a .css file.
If I don't clear cookies after a change nothing happens with the site..
Frustrating!
Someone have any good explanation for this strange behavior? :)
Thanks
Are you sure your CSS isn't just getting cached by the browser? The next time you modify your CSS file try performing a hard refresh (generally CTRL+F5 on Windows, CMD+SHIFT+R on Mac).
I'm not sure that cookies affect your styling but if you have issue with cached css file try adding timestamp to your css file:
<link rel="stylesheet" href="/your/path/to/cssfile.css?{Add a timestamp here}" />
also you can use a bookmarklet(it actually adds timestamp for you):
javascript:void(function(){var i,a,s;a=document.getElementsByTagName('link');for(i=0;i<a.length;i++){s=a[i];if(s.rel.toLowerCase().indexOf('stylesheet')>=0&&s.href) {var h=s.href.replace(/(&|%5C?)forceReload=\d+/,'');s.href=h+(h.indexOf('?')>=0?'&':'?')+'forceReload='+(new Date().valueOf())}}})();
the font of the content of my facebook app keeps getting italicized even when i've removed the italics from the css file. if i make minor changes in the css file and upload it to the server, the firebug shows the unedited previous css file and hence, the app keeps showing unformatted content. what exactly is going wrong here?
i made a new css file and copied the contents of the previous css exactly as it was, and i linked it in all the files which require css. but when i upload these files to the server, facebook canvas doesn't show any css at all. i replaced the css filename with the previous one, and it works. why is this?
Actually it looks like facebook is currently experiencing some weird problems with styling. It doesn't cache any new styles, only displays what was previously cached (from yesterday). If you provide a new stylesheet url it will not be able to pull it up (like that url doesn't exist).
During normal conditions what others already suggested should work.
Facebook does like to cache things. Persistently. I don't know why the new file wouldn't have worked, by I can recommend 'spoofing' your css filename with a spurious querystring variable, and incrementing it each time you make an update.
eg
href="my_css_file.css?x=1"
Sounds like the browser is caching your CSS file, which is why even Firebug sees the older version.
There are numerous ways you can prevent the browser from caching your CSS file during development (once in production mode, you probably want it to remain in the cache). The most common technique used by web frameworks like Ruby on Rails is to append a random query string to the URL, like so:
<link rel="stylesheet" type="text/css" href="style.css?96234987" />
...but the trick is that it should be different every time, so the browser thinks it's a different file.
Here are links to a simple trick for PHP, a JSP example, and other possible methods.
According to Include files on facebook developer wiki:
Stylesheet includes are cached automatically by Facebook. Just include a tag like:
<link rel="stylesheet" type="text/css" media="screen"
href="http://yourapp.com/stylesheets/style.css?v=1.0" />
Increment the version number upon each change to your style sheet, as specified above.
When I make any changes to my CSS file, the changes are not reflected in the browser. How can I fix this?
The fix is called "hard refresh"
http://en.wikipedia.org/wiki/Wikipedia:Bypass_your_cache
In most Windows and Linux browsers: Hold down Ctrl and press F5.
In Apple Safari:
Hold down ⇧ Shift and click the Reload toolbar button.
In Chrome and Firefox for Mac:
Hold down both ⌘ Cmd+⇧ Shift and press R.
Try opening the style sheet itself (by entering its address into the browser's address bar) and pressing F5. If it still doesn't refresh, your problem lies elsewhere.
If you update a style sheet and want to make sure it gets refreshed in every visitor's cache, a very popular method to do that is to add a version number as a GET parameter. That way, the style sheet gets refreshed when necessary, but not more often than that.
<link rel="stylesheet" type="text/css" href="styles.css?version=51">
A good way to force your CSS to reload is to:
<link href='styles.css?version=1' rel='stylesheet'></link>
And then just increment the version number as you change your CSS. The browser will then obey. I believe Stack Overflow uses this technique.
I always use Ctrl+Shift+F5 out of habit, it should force a full-refresh including by-passing any http proxies you may be going through.
I had this issue. Turns out I completely forgot I had CloudFlare setup on the domain I was live testing on.
CloudFlare caches your JavaScript and CSS. Turned on development mode and BAM!
Do Shift+F5 in Windows. The cache really frustrates in this kind of stuff
This sounds like your browser is caching your css. If you are using Firefox, try loading your page using Shift-Reload.
Having this problem before I found out my own lazy solution (based on other people suggestions). It should be helpful if your <head> contents go through php interpreter.
To force downloading file every time you make changes to it, you could add file byte size of this file after question mark sign at the end.
<link rel="stylesheet" type="text/css" href="styles.css?<?=filesize('styles.css');?>">
EDIT: As suggested in comments, filemtime() is actually a better solution as long as your files have properly updated modify time (I, myself, have experienced such issues in the past, while working with remote files):
<link rel="stylesheet" type="text/css" href="styles.css?<?=filemtime('styles.css');?>">
The Ctrl + F5 solusion didn't work for me in Chrome.
But I found How to Clear Chrome Cache for Specific Website Only (3 Steps):
As the page is loaded, open Chrome Developer Tools (Right-Click > Inspect) or (Menu > More Tools > Developer Tools)
Next, go to the Refresh button in Chrome browser, and Right-Click the Refresh button.
Select "Empty Cache and Hard Refresh".
Since I found this thread having the same problem, 10 YEARS later, I'll add my own solution too. I use PHP most of the time, and rather than requiring the user to press unusual buttons to refresh the page, or myself to remember to bump a version number embedded in a link, I used the filemtime() function to get the modification time of the css file (as a unix timestamp), and then use THAT number as the parameter.
$FILE_TIME = filemtime("main.css");
$CSS_LINK = "main.css?version=$FILE_TIME";
While results in a URL like:
http://example.com/blah/main.css?version=1602937140
This entirely disables caching, since every time the page is refreshed, it will believe it needs to grab the CSS file again, changed or not... but that's far less frustrating than forgetting to manually update this trick and wasting time wondering why it isn't right. You can always remove it from a production server.
If you are using plain HTML, you could probably engineer a javascript wrapper or some such, but that's probably more trouble than it's worth.
Have you tried renaming the new version of your CSS to CSSv2.css and then directing your page to use that? If that solves the stale-file issue, then you're just experiencing non-refreshing files. If not, you've got bigger issues.
If you're using ASP.NET web forms, make sure that you are using the right theme:
I just spent about an hour trying to solve this!
Is this a local custom CSS file? Is this your website? Maybe you should clear your cache.
Also the last CSS declaration takes precedence.
I faced the same problem. Renaming the file worked for me.
The reason this occurs is because the file is stored in the "cache" of the browser – so there is no need for the browser to request the sheet again. This occurs for most files that your HTML links to – whether they're CDNs or on your server, for example, a stylesheet. A hard refresh will reload the page and send new GET requests to the server (and to external b if needed).
You can also empty the caches in most browsers with the following keyboard shortcuts.
Safari: Cmd+Alt+e
Chrome and Edge: Shift+Cmd+Delete (Mac) and Ctrl+Shift+Del (Windows)
I'm working on a webapp, and every so often we run into situations where pages will load without applying CSS. This problem has shown up in IE6, IE7, Safari 3, and FF3.
A page refresh will always fix the problem.
There are 3 CSS files loaded, all within the same style block using #import:
<STYLE type="text/css">
#import url([base css file]);
#import url([skin css file]);
#import url([generated css path]);
</STYLE>
In any situation when we take the time to examine the html source, nothing is out of the ordinary. Access logs seem normal as well - we're getting HTTP 304 responses for the static CSS files whenever they are requested, and an HTTP 200 response for our generated CSS.
The mimetype is text/css for the css files and the generated css. We're using an iPlanet server, which forwards requests to a Tomcat server.
davebug asked:
Is it always the same css file not loading, or is the problem with all of them, evenly?
None of the CSS files load. Any styles defined within the HTML work fine, but nothing in any of the CSS files works when this happens.
I've had a similar thing happen that I was able to fix by including a base style sheet first using the "link rel" method rather than "#import". i.e. move your [base css file] inclusion to:
<link rel="stylesheet" href="[base css file]" type="text/css" media="screen" />
and put it before the others.
if it happens often enough that you're able to see it in your browser, try intalling the Live http headers Firefox extension or the Tamper Data extension, and watch the response headers as they are seen by the browser.
I don't know why, but in my case if the page is loaded from an action with the path like /ActionName, I see this problem.
But if I change it (for example) to /reservedArea/ActionName or /aPath/ActionName it works :/
It's crazy...
Examining the headers is a good idea, but I imagine all you will learn from them is that the server didn't respond to a request every once in a while.
I see this happen all the time on the net. Images won't load until you refresh, css is messed up, etc. All of the situations are solved by a refresh.
I imagine one way you could "fix" this, maybe, is by specifying in your cs file a url for an image for some element. Then, on page load in javascript, get that element and see if that image has loaded. If not, then have the page reload itself.
Seems pretty exotic, but that's the only idea I had...
Use ab or httperf or curl or something to repeatedly load the CSS files from the webserver. Perhaps it's not consistently serving the pages.
