The :checked
pseudo-class in CSS selects elements when they are in the selected state. It is only associated with input (<input>
) elements of type radio and checkbox . The :checked
pseudo-class selector matches radio and checkbox input types when checked or toggled to an on state. If they are not selected or checked, there is no match.
So when a checkbox is checked, and you are targeting the label immediately after it:
input[type=checkbox] + label {
color: #ccc;
font-style: italic;
}
input[type=checkbox]:checked + label {
color: #f00;
font-style: normal;
}
The label text will turn from grey italic to red normal font.
<input type="checkbox" id="ossm" name="ossm">
<label for="ossm">CSS is Awesome</label>
The above is an example of using the :checked
pseudo-class to make forms more accessible. The :checked
pseudo-class can be used with hidden inputs and their visible labels to build interactive widgets, such as image galleries.

if I move the order, how to write the css code?
I’ve repetition something like that, but confuse how to make it simpler like you had
The above is an example of using the :checked pseudo-class to make forms more accessible.
I’m using this technique to hide/show navigation menus in a responsive layout. However, I’m discovering that since the LABEL tag cannot have FOCUS, that this technique is not at all accessible (at least not to keyboard users). Is there a way around this?
Also, in my experience the adjacent sibling selector (‘+’) does not work in iOS (must use the general sibling selector ‘~’).
IOS 8 seems to be sensitive to this. Fixed my problem to change from + to ~ ! Thanks!
Might be worth mentioning that unchecked checkboxes can be specifically targeted by using
:not(:checked)
.Browser support is almost the same. See https://css-tricks.com/almanac/selectors/n/not/
Hello Dennis, thank you very much for your comment.
Hello,
any ideas/tricks to use it on ie8 as long as :checked does not exist?
Thanks
Hi, for ie8 I add class ‘checked’ and use
input[type=checkbox].checked + label {
color: #f00;
font-style: normal;
}
there are various types of input fields in a HTML page such as text, number, email, radio, checkbox. Now how will i modify style to all input
except radio and check box. is it right code if i do that this way :
input:not([typy=”radio & checkbox”]){
float:right;
}
Sadly putting the label after the relevant field means that the field/label pair are not accessible according to the WCAG 2.0. There are a lot of examples of this field + label pattern out there but in order for the markup to make sense to all users and assistive technology the label should come first.
I await the day we can use selectors which target the preceding item

Apologies, the above statement isn’t actually correct, it was the Surfright standards that stipulated this. Labels after radios and checkboxes are valid. The WCAG 2.0 guidelines state that radiobuttons and checkboxes can have the label positioned after and (as far as I can tell) that this is a matter of visual positioning only.
Thank you man!
Browser support: Android: any?
No, unfortunately not. You named it. Android 4.2 is still affected. Your proposed hack has severe performance issues on some devices.
I don’t have an other solution, though.
Is there any solution if we want to repeat the “id” along with “check box” more times????? I need more check boxes and labels in my project..
:(
(Excuse me for my worst English)
Hi
Can any one tell this
i have two radio button.
If i check one radio button , i want that other radio button should be checked. means check other radio button on another radio button’s checked.
hi
One more thing it should be done by HTML and CSS. Without any use of javascript
Hey Jugal. You can’t do that with radio inputs. Only one radio input can be selected at a time. Instead you want to use:
input="checkbox"
However you will need to use some JS to toggle other inputs if one is selected. Can’t be done solely with HTML and CSS.
All CSS3 pseudo-classes are pretty cooool. They not just make the life of a web designer so easy but also they focus on more semantic, clean & simpler code. Not to mention, CSS4 has already offered us more yummy awesomeness.
Be warned this code will NOT work as expected in Safari 5.0.1 if you apply it to UL element.
Has anyone tried to do this with :focus?
@Tim
I just finished something using the :focus selector yesterday. I styled my label as if it were a ‘
<div>
‘ inside of an actual<div>
. The :focus selector runs a check on the checkbox, not the label itself so you can’t use display:none on it. To combat that, I simply moved it up and left 9999px from the page. Also, I need a checkbox for each of my labels(‘<div>
‘s) so I have to have CSS instructions for each one individually which is why I’ve numbered my id tags. This works for me because I have a known amount of boxes on my page.If someone knows an easier (or more efficient way) of using selectors, feel free to correct me. I just started dawdling with CSS about a week ago.
I’m using Firefox 38.0.5 for all of this on a Windows 7.

I’ve implemented an off canvas menu on my site but the sitewrap won’t slide out to reveal the menu on iOS 4 and 5, it works just fine on all other devices and browsers. Nothing happens at all when the nav trigger is pressed so I’m assuming it’s something to do with the pseudo element ‘:checked’.
I would appreciate any help anyone can give, it’s driving me nuts Lol!

It seems to be broken again for Chrome on iOS 9. See this issue https://code.google.com/p/chromium/issues/detail?id=534210

How would I use css to select read only radio buttons?
How would I use css to select radio buttons that are both read-only and checked?
But
readonly
is ignored on radio buttons, so it’s nonsensical.How to disable radio button after selection
https://jsfiddle.net/ajshres/skmw6hjd/
how much will it make a difference if I use label as parent and span or div as the sibling and not use for and id.
for list of checkbox, id might have to be generated unique and if we donot have to use id, would be a lot cleaner

Checkbox to alternate Submenu on/off over background. iphone safe?
I’m reading that :checked pseudo selector also works with select options, affecting the option the user selects, not just checkbox and radio buttons. It was news to me but makes sense.
Also interesting: there is a 3rd state for checkboxes, radio button groups and bars. It is :indeterminate and can be set with JavaScript.
Hi, Can anybody help me? I’m practicing a to-do list website and I added the following attribute to my CSS file. It doesn’t allow me to uncheck any checkbox after it was checked. What should I do?
If I remove this attribute, any checkbox can be checked or unchecked.
I’m working on Google Chrome Version 64.0.3282.140 (Official Build) (64-bit).
Hm, that’s odd. The CSS should not change the state of the checkbox, but merely style it based on the state of it — in this case, when it is in a checked state. Have you tried removing one each property individually to see if one of them is the culprit? That might help isolate the issue, if it is in the CSS.
I did some cleaning and now it’s working just fine! I don’t remember what was the previous state in order to compare them and learn about it :-\ Thank you for your help.
I try this, but it seems I cannot target an alement which is outside the form element where the checkbox is. Is this not possible?
Hey there! Do you happen to have a link to a Codepen (or some other demo with the code) where that is?
How can I get different styles for different checkboxes’ labels, on same page?
I’ve trying several ideas and nothing works for me.
I always get the same style for all my labels on different checkboxes.
Thanks in advance.
You can use parent class.
