Chrome created unknown css style snippet by itself? - css

I've created a micro page with absolutely no external references, even without any favicon.ico.
Instead I'm using base64 inline images.
The only CSS I'm using is inline of a <div> element.
The following code is not part of my source, so I don't know where it becomes generated.
Where and how does the following code come from?
What is it's meaning? What consequences does it have?
Fulltext for copy&paste:
<style type="text/css" style="display: none !important;">object:not([type]),object[classid$=":D27CDB6E-AE6D-11cf-96B8-444553540000"],object[classid$=":d27cdb6e-ae6d-11cf-96b8-444553540000"],object[codebase*="swflash.cab"],object[data*=".swf"],embed[type="application/x-shockwave-flash"],embed[src*=".swf"],object[type="application/x-shockwave-flash"],object[src*=".swf"],object[codetype="application/x-shockwave-flash"],iframe[type="application/x-shockwave-flash"],object[classid$=":166B1BCA-3F9C-11CF-8075-444553540000"],object[codebase*="sw.cab"],object[data*=".dcr"],embed[type="application/x-director"],embed[src*=".dcr"],object[type="application/x-director"],object[src*=".dcr"],object[classid$=":15B782AF-55D8-11D1-B477-006097098764"],object[codebase*="awswaxf.cab"],object[data*=".aam"],embed[type="application/x-authorware-map"],embed[src*=".aam"],object[type="application/x-authorware-map"],object[src*=".aam"],object[classid*="32C73088-76AE-40F7-AC40-81F62CB2C1DA"],object[type="application/ag-plugin"],object[type="application/x-silverlight"],object[type="application/x-silverlight-2"],object[source*=".xaml"],object[sourceelement*="xaml"],embed[type="application/ag-plugin"],embed[source*=".xaml"]{display: none !important;}</style>

I can think of two possibilities:
1) Added by a browser plugin or extension.
Try running in Incognito mode with all extensions disabled, and if it's due to a plugin or extension the additional content will go away.
2) Added by the web server that is serving the web page
To see if it's #2, load the HTML file in your browser using a local file:// URL and check if it's still there.
Most likely it's related to an Ad-Blocking type of browser plugin that is setting { display: none !important } CSS attribute for all Flash, Shockwave, Silverlight, etc. content on the page.

IIS renders embedded font icons incorrectly

I have a static web page that displays icons embedded in one of the css references. The icons are not displayed properly and we see some junk characters instead when browsed to from IIS. The same web page when opened directly in the browser seems to render fine. I wonder if it is some misconfiguration in the static page website but I am unable to figure out what the issue could be. Would greatly appreciate any help to solve this issue.
The page when rendered by IIS:
The page when rendered by browser directly:
Looks like the CSS file is the issue.
The css file when browsed to via IIS:
The original css file opened with the browser:
If you use extended styles and sass syntax, when SASS does the compression, it changes Font Awesome characters from escaped ASCII sequences to unicode. So you need to add <meta charset="utf-8" /> in the head to let the browser know how to interpret it.

codeigniter website on a host- CSS changes does not change front end elements

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.

Shopify: Can't load external stylesheet from another server

https://friends-with-you.myshopify.com/
I'm trying to develop my first shopify theme. I'm trying to load a stylesheet which is hosted on another server, but the CSS is not loading. If I copy and paste that CSS directly into a file in the shopify theme, it works.
<link type="text/css" rel="stylesheet" href="http://fwy.pagodabox.com/magic/themes/fwy/fwy.css" />
What am I doing wrong at the above URL, and why isn't the css loading?
thanks!
Can you load your CSS file over both http and https? If so, change your tag to look like this:
<link type="text/css" rel="stylesheet" href="//fwy.pagodabox.com/magic/themes/fwy/fwy.css" />
That way whether a user visits using http://yourstore.com or https://yourstore.com, they'll get the stylesheet served using the protocol they're on (and you won't get any mixed content warnings).
A little more background: http://paulirish.com/2010/the-protocol-relative-url/
Under IE7 and IE8, using this in a <link> tag will result in your content being fetched twice.
Change your link tag to use a secure URL:
<link type="text/css" rel="stylesheet" href="https://fwy.pagodabox.com/magic/themes/fwy/fwy.css" />
^
The URL you're using now works fine on its own, but since you're browsing to the Shopify store over SSL, many web browsers are going to be hesitant to load the CSS over an unsecured connection.
I just checked and pagodabox serves the CSS file just fine over SSL.
In normal HTML documents one can load stylesheets from anywhere, as long as they exist and you're able to load them by typing the URL in (which I can).
I see the page as two navigation bars with a logo on the left hand side. There are hover states with transitions to a colour background on each item. Although, when I loaded the page, Chrome warned me not to load supposedly insecure content. Before this is loaded I just see text in Times New Roman. I think this is you problem.
I use themes with WordPress and style-sheets come with them (mostly). I don't see why you couldn't just put the style-sheet in with the rest of the theme.
Overall, the answer is yes (normally) but in this case browsers may regard it as un-safe and therefore not load it.
Yes you can! But it is faster to host the stylesheet on your server/where the other files reside. If you plan to include a stylesheet from elsewhere, you could run into problems of that server being down/busy and hence your theme will not display as required. As #Blieque mentioned, some browsers may question external content causing unnecessary warning popups to a user/user-agent.

How do tools like the web dev toolbar get the entire css file of a site?

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.

What might cause CSS to fail to load occasionally on all browsers?

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.
