I need write rules for pseudo elements specifically for Edge and IE, but It seems that both of these browsers are not showing ::after and ::before pseudo elements in their developer tools despite them being rendered on the page.
Is there way to edit them directly in browser, as it is possible on Chrome or Firefox?
Edge shows pseudo element styles on the given element, but after other (even inherited) styles....
So scroll down.
I'm trying to view/edit styles of an :after element in Developer Tools.
How may I find the rules associated to ::before and ::after pseudo-elements?
Found it. You select the element that has the :after and the :after styles will be listed with the other styles for that element.
In Chromium browsers (e.g. Chrome, Brave and Edge), open the element's collapsed content and click on the automatically added ::after element:
Firefox though has an independent Pseudo-elements section on the right pane after you click directly on the original element:
IE11 simply lists the ::after rule together with other element rules when you click on it:
Background story: I have a page with multiple CSS that override each other. There are so many crossed out CSS style, so I don't want to see them.
I know Firebug on Firefox provide this feature (Only Show Applied CSS), which can show what CSS style in what CSS file is being applied (neat !).
How do we have this feature on Chrome ? I tried install Firebug Lite for Chrome but no luck.
PS: Chrome have Computed Style tab, but it does not show what style come from what CSS file.
In the Chrome dev tools, in the right hand column (where CSS is shown in the Elements panel), the first section is called "Computed Style". If you deselect "show inherited", you get a neat list of the styles that actually apply to the element. Does that help?
I have created some fairly elaborate DOM elements with an :after pseudo-element, and I'd like to be able to inspect and tweak them in either Chrome Inspector or Firebug or equivalent.
Despite this feature being mentioned in this WebKit/Safari blog post (dated 2010), I can't find this feature at all in either Chrome or Safari. Chrome does at least have checkboxes to inspect :hover, :visited and :active states, but :before and :after are nowhere to be seen.
Additionally, this blog post (dated 2009!) mentions this capability exists in the IE dev tools, but I'm currently using Mac OS, so this is no help to me. Additionally, IE is not a browser I'm primarily targeting.
Is there any way of inspecting these pseudo-elements?
EDIT: In addition to being wrong about Firebug being unable to inspect these elements, I've found Opera to be pretty good at Inspecting :before and :after elements out of the box.
In Chrome's Dev tools, the styles of a pseudo-element are visible in the panel:
Otherwise, you can also input the following line in the JavaScript console, and inspect the returned CSSStyleDeclaration object:
getComputedStyle(document.querySelector('html > body'), ':before');
window.getComputedStyle
document.querySelector
As of Chrome 31 pseudo elements show in the elements panel as child elements of their parent as shown in the following image:
You can select them as you would a normal element but if you remove the content style then the pseudo element will also be removed and the devtools focus will change to it's parent.
It appears that inherited CSS styles are not viewable and you can't edit CSS content from the elements panel.
Chrome won't show :before and :after pseudo elements in the DOM-tree, if they miss "content" attribute. It should be set, even if it is set to nothing.
This won't show up:
:after {
background-color: red;
}
This will show up in the inspector:
:after {
content: "";
background-color: red;
}
Hope it helps.
At least since Chrome 62 there's a setting in DevTools to 'Show user agent shadow DOM' which displays additional pseudo-elements like input placeholders, which wouldn't show up in the DOM tree otherwise.

After a lot of frustration, I figured out that firefox doesn't show the pseudo elements in the document tree at all, but if you select the exact element which has pseudo element(s) defined, then the styles for its pseudo element(s) are shown in the style rules section on the right side. This is true for both firebug and the built-in inspect ("Q"), and I am shocked that nobody bothered to explain this clearly before.
Clearly, chrome/chromium's handling of pseudo elements is vastly superior, as they can be selected (both in the document tree and directly on the page) and inspected just like regular elements, with layout, properties and everything else, independent of their "owner".
Browser versions I'm using currently: Chromium 40.0.2214.91, Firefox 31.3.0.
Firefox has had this feature for awhile now, just right click, "inspect element", and see the before and after elements in the right panel of the inspector.
Select Element--> select hover checked ---> you can see ::before and after elements
Is there a way to move the checkboxes that disable CSS styles in the WebKit Inspector that is baked into Safari and Google Chrome from the far right over to the left, next to the declaration how Firefox's Firebug does it? To disable styles, one must go over to the far right, which can be hard to eye trace when the style declaration list is very long. On top of that, sometimes the new Lion style scrollbars can get accidentally clicked. I hear that even the Web Inspector in WebKit is laid out via CSS, so this should be relatively easy. Any help? Even if someone could get me to the style sheet for the WebKit inspector I could figure out the CSS. Thanks in advance!
Here's some screenshots to demonstrate what I mean:
