I've just been tasked with migrating a website from a Windows server to a Linux server.
One of the issues I've noticed straight away is that there are a number of CSS url() definitions that don't work because the case in the CSS is not the same as the actual file.
eg:
background: url(myFile.jpg);
while on the server the file is actually MyFile.jpg.
Does anyone know of a simple tool or browser plugin I can use just to scan the CSS file and verify that the url() declarations exist so that I can easily find and fix them?
The site is quite large, so I don't want to have to navigate through the pages to find 404 errors if I can avoid it.
Use Developer Tools in Google Chrome or Firebug in Firefox.
When you load HTML page with that CSS, it will show any missing resources in Network tab.
EDIT
I guess there is no any tool that will
Scan through CSS file for all the URLs
Check whether each URL exists or not.
But you can try following two links for these two tasks.
RegEx to get the URLs from CSS : With this you will have all list of URLs used in CSS
Check if a URL exists or not with cURL : An example in PHP was given.
You can still search for these two items separately and try fixing the issues.
Let me know if this helps.
What, if you simply write a http request into browser's URL bar pointing directly to the image and/or css?
How about firebug in firefox? It would give you all 404 in its console.

You can install Firebug if you're using Firefox or you can press F12 if you're using Chrome.. i think that goes the same with IE.. From there you will be able to check the URL and even view it in a new tab.
Turns out that the W3c Link Checker also scans CSS files which is very handy.
Had this have not worked I would have had to put together something like Vanga's solution.
Here's how I would approach this.
Make sure all image requests are handled by a (PHP) script, by adding the following to my .htaccess
RewriteRule .(?:jpe?g|gif|png|bmp)$ /images.php [NC,L]
Use file_exists() to check if the file exists, maybe even try if a lowercase version of the file exists.
Log missing files into a database table or text file.
Use a script to loop through the website's sitemap with curl to get a complete list of requested filenames that resulted in a 404.

I am helping out a friend with a slow WP. I installed hummingbird and it's telling me that some css files are slow to load (for example: https://cdnjs.cloudflare.com/ajax/libs/gsap/1.11.2/TweenMax.min.js - it takes 390ms to load). I would like to store this file locally and see if the performance improves. The problems is that I'm not sure about how to locate the file that is actually requesting this css file. Any help is appreciated.
I suggest a sweet plugin I use called String locator. It will search the whole site for a string like TweenMax.min.js. It will also search by plugin. When it find it it gives options to edit straight to the file. Hope this helps.
Not sure how to really categorize this question, but on this page, the file http://d1el287zd12c0j.cloudfront.net/assets/hitgrid-0a8239a14fba0de87431c06cd75774f3.css seems to be completely ignored by browsers. It appears to load successfully and no different than any other css file on the page, but the styles in it are simply not applied to the page.
The content-type, encoding and everything appears to be working as expected. Roughly the same content "applies" fine on my local installation of the app.
I'm at a loss as to what's going on here.
I just check it out and everything went right.
Try to make the filename shorter in the CDN. Large names tend to make error in some way or maybe check if no other stylesheet is interfering with the styles
If that didn't work, answer these questions and Ill try to git it a try again
Which OS are you using?
2. Are you using wordpress?
We're having a weird problem at work that happens only in chrome. It looks like the css file is getting cached and the content of this file isn't getting re-downloaded.
The problem is that when using a fresh session for example "private session", the image "mainSprite.png" isn't getting displayed.
After some tests, I believe the problem is related to us doing redirects at the beginning if the user isn't authenticated. From what I understand, it might not complete the download of the sprites linked inside the css files. It will cache an invalid object as soon as the redirect starts and then on the following pages, it will fail to display a correct image since it cached something wrong.
The strange thing is that it actually loads the image completely at some point. But it looks like it's not refreshing it in memory...
I did a timeout of one second before starting redirects on first load and images correctly display. This is a quick fix and I can't expect every computer to load in 1 second every images contained in the css.
edit
As far as I can say, it really looks like a race condition. I changed the order of loading. We use require.js. Instead of loading js after css, I start js loading before. And images are getting loaded correctly now on my local server.

When images aren't visible, opening new tabs will have the same problem. Closing the browser and reopening it will work on first load and images isn't being downloaded but loaded from Cache which means that before closing the browser, the image was indeed downloaded.
It looks like the problem coming from your redirects unfortunately i couldn't see your example ( link won't open ). Google chrome has indeed issues with caching it's annoying during development time ( clear up the cache, load new image, do the same for new image..), if you need to clear your cache try the folowing:
try to go to
chrome://chrome/settings/clearBrowserData
in your chrome browser and check the options:
Empty the Cache( i have also Clear download history and Delete cookies and other site and plug-in data )
click on 'Clear Browsing Data' button it should
All what you need to do is to trace your cash list via chrome, and from what I see is that you got this error which make it not cached:
Uncaught TypeError: Object [object Object] has no method 'placeholder'
So if you want to trace, you can use the manifest offline mode or you trace via your code.
Just following and test your page, I did catch where the error is:
file: scripts2.js Line 20 --> $('input[placeholder]').placeholder();
which you need to check the name of the place holder and change it here in this tag.
Thank you
I assume your server/backend app has routes set up. Like this Play! framework example:
# Ignore favicon requests
GET /favicon.ico 404
# Map static resources from the /app/public folder to the /public path
GET /public/ staticDir:public
# Catch all
* /{controller} {controller}.index
According your summary I suggest to set up a static folder route (where the images are) in config file or htaccess as you want, then check image url in browser url bar (with empty session). That should work!
First I would suggest that you first try to find ways to narrow the redirects. If it possible I would suggest that it would be much more advisable to try to create your content dynamically based on your users authentication using languages like PHP or ASP (just to name two).
The classic way of disabling the caching on a webpage is to set two <meta> tags inside of your <head> </head> tags. However, you should note that these are technically not "correct" as they are not part of any of the "offical" standards documentation. This also means that I would again lean towards my first suggestion of finding a better delivery system which in turn should prevent the problem.
So for "testing" purposes the tags would be:
<HEAD>
<META HTTP-EQUIV="CACHE-CONTROL" CONTENT="NO-CACHE">
<META HTTP-EQUIV="EXPIRES" CONTENT="0">
</HEAD>
Maybe I don't understand your question or dilemma (maybe because of lack of explanation or because I can't see your page at that link since I run Chrome), but there's an example I ran across here that works in Chrome by just using Javascript/jQuery to load, instead of CSS:
http://jsfiddle.net/2Cgyg/6/
Use image at URL: http://www.w3schools.com/cssref/img_tree.gif
And although the accepted answer didn't work for me in Chrome, this is the question I got the jsFiddle above, from:
Load Image from javascript
All the caching, etc. is unnecessary, and even something you wouldn't want to do if your images are ever updated to something else - they won't appear without forcing a refresh which you can only do through altering the file name like this to avoid users not seeing your updated image:
myPic.jpg?MMDDYYYY
And you could set the date according to the date you are modifying it.
clean your browser history like cache,cookies
clean the temporary internet file
if problem not solved then reinstall browser your problem is solved definitely
I need to modify a couple of classes in the css of the site i'm currently woking on. another person worked in it, so i really don't know where he has put the styles. i know firebug shows the css path on the corner, but it's just showing the url like this: http://localseo.org#3(line 149) . what does it mean? how do I get the file path? Thanks for the help everyone.
Click on that URL.
It will open the correct file to the correct line. From there you can easily see the path...
However, if you mean file path, on the server, you cannot get that from the browser or Firebug; it depends on your server settings.
Open firebug and you'll see a CSS pane/tab you can then select the stylesheet you want/need to edit.
The web dev toolbar for Firefox is quite an impressive tool.
What I am completely clueless about is how does this tool get the css stylesheet file of a site? This is hosted on a host which is secure etc. I am completely stumped.
I must be thinking about this in all the wrong way.
Thanks
The client (in this case Firefox) has to download the CSS file in order to render the page correctly. The plugin (in this case Firebug) simply requests the proper URL and the browser it gets it--most likely from the cache. There is no real mystery here.
In every HTML file, there's a link to the CSS stylesheet, or else the browser wouldn't know where to find it, thus losing the ability to render the page correctly.
It's in the form of <link rel="stylesheet" type="text/css" href="theme.css">,
I'd like to add that regardless of whether the host is 'secure' or not, it still is presenting the file to the client.
Unless, of course, you're looking at a XML file. Then you need to consult the XSL which'll tell you where the stylesheet is.
