Google Chrome Developer Tools - unable to edit CSS - css

I'm using Google Chrome developer tools to try different CSS values on a localhost site e.g. changing "border-width: 1px" to "border-width: 2px".
For some reason I am unable to edit. If I click on "1px", I can type in a new value e.g. "2px" but as soon as I hit return, the value returns back to "1px".
For some reason, it is only affecting one site - all other sites I can edit fine.
Any ideas what the problem might be?
Earlier on, I saw a "paused in debugger" notification at the top and the page greyed. Might this have something to do with the problem?

I discovered that the problem was the use #import in the site's style sheet, specifically:
#import url('http://fonts.googleapis.com/css?family=Open+Sans');
Once this was commented out, I was able to edit the CSS again.

What does the colon in the styles tab of Chrome dev tools mean?

I googled the heck out of this and could not word my search properly to find the answer. I'm working on a Wordpress site that is letting me edit the stylesheet (style.css) via the Editor, but the changes aren't appearing on the website, the old css is still being shown for some reason. I have cleared my browser cache to no avail.
Anyway....
Using Chrome's dev tools show the old styles are being pulled from things like style.css:90, style.css:400, style.css:9, etc...
What does that mean? Where are those numbers coming from?
Are the numbers the line numbers from your CSS file? As in the code/style declaration on line 90 and line 400 from your style.css file.

Css background Wont work?

I have a question.
I am currently building a "blog" website. Not that it matters but..
I am trying to set my background to be a specific image that i have.
And it used to work! Until recently and I just don't know why it wont.
It works when i am on my computer, everything works fine.
But i am using 000Webhost as the hoster for the website.
So if u go to "http://pontuslundhblogg.uphero.com/"
You might see that the website is completely white. Cause the picture wont load for the background.
In my css sheet, i am using:
body {
background-image: url("bakgrund.jpg");
And yes, i did name the picture bakgrund.jpg and uploaded it to 000webhost. Its the exact same name etc. I wondering.. Could two different css stylesheets make so it gets weird or something? Cause I added a second css style sheet to be able to have a drop-down menu in a different sheet, and i added the drop-menu. Around that time it started messing with me..
Is it me doing something wrong.
Or is it 000Webhost?
(Might add that none of my pictures is working now, i can also contribute with more code if needed!)
If you go to pontuslundhblogg.uphero.com/bakgrund.jpg you get a message
"The image pontuslundhblogg.uphero.com/bakgrund.jpg cannot be
displayed because it contains errors".
If you go to pontuslundhblogg.uphero.com/bakgrund1.jpg you get 404 page, which means that the first path (bakgrund.jpg) is correct - but the image itself isn't good.
Try to upload it again or contact the hosting service.
If you use FTP maybe you need to change something in your FTP program settings - maybe change from ASCII to Binary transfer.

Internet Explorer not loading external styelsheet

So, I'm working on a clients page that's hosted with BigCommerce and it appears that all of the custom styles I wrote are not being recognized by internet explorer. It works fine in all other browsers.
It's strange because IE sees the .css file, but when you click into the stylesheet in developer tools, none of code populates.
I don't have more than 31 stylesheets so that's not the issue. I'm at my wits end and any help would be greatly appreciated.
The website is www.bangsshoes.com.
The stylesheet is .../bangs.css
Just a thought, but you could:
a) try combining the styles into another style sheet which is being successfully incorporated or,
b) since this is just a reset, try another reset? or a modenizr? http://cdnjs.cloudflare.com/ajax/libs/modernizr/2.8.2/modernizr.min.js
Another test would be to comment out the other style sheets and see if that makes a difference-- it's possible another style sheet is interfering (though unlikely!)

Chrome inline background-image lost on back-button in Chrome

I have an inline style on element on one of my templates.
- hero_image = article.hero.url(:medium) if article.hero.url
%article{style: "background-image: url('#{hero_image}');background-attachment : fixed;"}
It works marvelously for me. Except when I go to another link and the use the back button to return the page.
When I use the back button to return the page, the inspector the source is the exactly the same, but no image. When I refresh the page, same code, but the image is there. Seriously weird and annoying.
I've seen reports of this being a bug in Chrome related to background-attachment:fixed; but the work arounds they suggest don't work.
Is there a way to force (via Turbolinks?) this element to refresh?
It turns out that the issue is fixed by adding the base url to the url like so:
- hero_image = base_url + article.hero.url(:medium) if article.hero.url
%article{style: "background-image: url('#{hero_image}');background-attachment : fixed;"}
(I added a base_url helper thanks to this: https://stackoverflow.com/a/2952576/1291663)
I've run into the same problem on my app, trying to display user avatars.
There are (many) bug reports related to this particular situation dating back a couple of years, but the bug is still present as of time of this writing.
The solution I've gone with is to replace the background with an actual img tag, and than use z-index tricks to push it back.

Export CSS changes from inspector (webkit, firebug, etc)

When I'm working with CSS, I'll often test in a browser - say, Chrome - right click an element, click Inspect Element, and edit the CSS right there. The use of arrow keys to change things like margin and padding makes lining things up super easy.
It's not too hard to then take those changes and apply them to the CSS file, but it would be cool if I could just right click the selector in the inspector and select "export" or "copy", and have the contents available in my clipboard.
Does something like this exist?
I have found the answer to this, at least as of Chrome v14.
While in the Elements section, just click on the "filename:linenumber" link next to the CSS rules. The CSS file that shows up will contain all of the modifications.
This place exactly:
In Chrome, you can right-click a CSS file in the Sources tab and click "Local Modifications"
This shows you all of your local changes. Each revision is timestamped and you can rollback to any previous revision.
See the Live Editing and Revision History section of this tutorial.
Firediff is a Firebug add-on that tracks changes done in Firebug. It logs everything you'll do in the HTML pane (great) but also your brief use of the Web Developer Toolbar extension (not so great), say Shift-Ctrl-F to obtain a font-size information in px.
I have seen a Firebug extension in Chrome but didn't test it, I use Firediff with Firefox.
In Chrome there is also the Changes tab in the console drawer that displays all the modifications of CSS. It's not an export, but at least it is very convenient to quickly grasp what has changed.
I built a Chrome extension that does exactly this.
It's called StyleURL - it takes whatever CSS changes you made in Chrome Inspector and outputs valid CSS as the diff: https://chrome.google.com/webstore/detail/styleurl/emplcligcppnlalfjknjbanolhlnkmgp
Here's an example where I added "padding-bottom: 50px" to this page:
It's open-source and on GitHub too: https://github.com/Jarred-Sumner/styleurl-extension
Both Firefox and Chrome support this feature now, but worth to note that in some platforms if not all Chrome does not show it by default, you need to enable the "Changes" view to see it (in my Kubuntu Linux 20.04 it wasn't by default), here is how you can enable it: go to the "Customize and Control DevTools" button in the Developer Tools bar > "More tools" > "Changes", then the tab will appear at the button:
In Firefox there is no need to enable it, but if you come from the Chrom* world may be hard to find it. Just check the last section in the right at the "Inspector" tab:
I've suggested this product on SO before (I'm not affiliated with them in any way).
http://www.skybound.ca/
Excellent product. Sounds like exactly what you're looking for and much more.
EDIT: Several other answers here have mentioned Google Chrome's ability to link to your local files (which is very very cool). Check out the other answers!
If you edit external CSS, then you can drag its latest revision out of the Resources panel into any text editor that supports DnD (see http://www.webkit.org/blog/1463/web-inspector-styles-enhanced/, the "Persisting Changes" section for more detail.) You can also revert your CSS changes to any earlier version of the stylesheet resource (in the right-click popup menu of any stylesheet revision.)
As mentioned by cloudworks, the answer to this has changed. This can now be accomplished rather well by the Chrome DevTools Autosave extension. This tool tracks CSS and JavaScript changes made within the Chrome Developer Tools console, and saves them back to local files. For instructions to install and setup the extension, please refer to the guide written by #addyosmani on his blog, here.
There is also a handy screencast which details the extension rather well.
With Workspaces you can have your CSS saved as you type them in your inspector (in Chrome). The problem is that every change is automatically saved and there's no way to disable this feature, as pointed in http://www.html5rocks.com/en/tutorials/developertools/revolutions2013/ and Disable automatic saving of CSS changes in Chrome Developer Tools.
My in-beta-soon product LIVEditor does this exactly.
To let you understand it easily, you can think of Firebug's inspector is embedded into your text editor.
That way you don't have to make the changes manually again in your code editor after you tweaking it using Firebug or Webkit's developer tools.
If you're using the Firefox stock dev tools you can edit the css directly in the tools dialog - click the CSS viewport button (that's the button at the top with the {} symbol) and edit your css directly. It will update in realtime in the browser and when you're done just copy-paste it directly into your css file. Nice!
To add an answer for Safari specifically — it's kind of possible.
When you edit CSS in the Styles section in the Inspector for an existing CSS file, you can hit Cmd-S to re-save the entire file with the changes. However, if you're using a meta language like Sass / preprocessor / generating your CSS with bundling etc, I don't think this really solves that problem, though it may be possible with CSS source maps.
When you edit CSS at the top of the Styles section, under Style Attribute to add inline styles (not tied to an existing CSS file), it doesn't seem possible to easily export all of those changes. For now, I'm just copying and pasting the overrides manually for each element.
The official Apple docs are a little dated but found here: Web Inspector Tutorial - Editing Code to Change Your Webpage.
In Chrome, in the css inspector you can click and hold the + button, then choose to add your changes to the inspector-stylesheet. It's not as convenient as directly editing in your css-selectors, but what you write will all be in inspector-stylesheet.css
