Is there a way in html markup to have a checkbox greyed-out and checked?
I wan't to keep the checkbox styled depending on the browser, so not alter it too much with css.
I'm trying to have a row of 4 checkboxes. One is checked and blue by default, the other three are disabled and greyed out. When you either:
- click on the first one the other three become actively blue again
- or when you click on one of the three disabled ones the first one becomes inactive
<input type="checkbox" checked disabled />
<input type="checkbox" checked onclick="return false"/>
OR
<input type="checkbox" checked disabled />
The disabled will gray it out, the first example won't
Add disabled="disabled" to the end of the input tag. If you wanted the checkbox to be ticked on load add checked instead.

I'm trying to be WCAG friendly and have created a group of radio buttons, which, when they receive on-change, trigger action. But when I tried to navigate it by shift+arrow, I discovered that it doesn't just focus them, but right away checks them on? Am I missing something here, or is that normal behavior?
Edit:
The code looks like this for example:
<input type="radio" name="month" value="jan">January</input>
<input type="radio" name="month" value="feb">February</input>
<input type="radio" name="month" value="mar">March</input>
You didn't post any code so I'll assume you're using
<input type="radio">
and that you have several of them all with the same name attribute and that each radio button has a properly associated label with them. (Lots of assumptions but we can only guess if you don't post any code.)
When no radio buttons are initially selected, different browsers treat navigation to them differently.
On Firefox, I can tab to each radio button in the group.
On Chrome, I can only tab to one radio button in the group.
The tab does not select the radio button. It only moves the focus there.
Once my focus is on a radio button, then the arrow keys perform two behaviors:
It moves the focus to the next (or previous) radio button in the group and
It selects the radio button.
It sounds like you're asking about #2 behaivor. If so, then what you are seeing is normal behavior.
Default tab indexing is NOT working with radio buttons, working fine with any other HTML component e.g. checkbox, textbox etc.
Below basic code not working for radio button tab index but working fine with checkbox.
<div class="box">
<input type="radio" name="rdgroup">H
<input type="radio" name="rdgroup">E
<input type="radio" name="rdgroup">L
</div>
<div class="box">
<input type="checkbox" name="ckgroup">W
<input type="checkbox" name="ckgroup">O
<input type="checkbox" name="ckgroup">R
</div>

Thank you :)
Essentially a radio button is a group that functions as a single element since it retains only a single value. Tabbing to a radio group will bring you to the first item and then using the arrow keys you navigate within the group....
When you assign same name to the ratio buttons, it treats you like a one control. However when you don't select anyone you can have a focus on first one and then use arrow button to select the one you want to.
Focus can move to a radio group via: The Tab key An Access Key or
mnemonic targeting the label Activation of the label (through
Assistive Technology mechanism)
The Tab key moves focus between radio button groups and other widgets.
When focus is on the group and when no radio button is selected: Tab
key press moves focus to the first radio button in the group, but does
not select the radio button. Shift+Tab key press moves focus to the
last radio button in the group, but does not select the radio button.

As #Just Code said:

For radio buttons as a group if they have the same name then changing focus will work or navigate with arrow keys like (right, left, up, down).that is the default behavior of radio buttons, it is better to leave it as default. If you prefer tab control then i guess you have to implement it with javascript, because if you give them different name user can select all different radio buttons
enter code here
<div class="box">
<input type="radio" name="rdgroup" tabindex="1">H
<input type="radio" name="rdgroup" tabindex="2">E
<input type="radio" name="rdgroup" tabindex="3">L
</div>
<div class="box">
<input type="checkbox" name="ckgroup">W
<input type="checkbox" name="ckgroup">O
<input type="checkbox" name="ckgroup">R
</div>
you could use the tabindex attribute to get a workaround after the first radio button element gets focused the user can then use the arrow keys (default) to select the desired option.

I encountered a problem, where one radio button group is dependant on other state, which caused a disabled radio button to be selected. This is not a problem when selecting another value in the radio button group with the mouse for example, but it seems it is impossible to tab to the radio button group now. I realise that I maybe should not let this happen, but I think it is strange that you can build radio button group that you cannot change by keyboard alone. Here is a simple example:
<input type="radio" disabled checked name="test" value="1">
<input type="radio" name="test" value="2">
<input type="radio" name="test" value="3">
<input type="radio" name="test" value="4">
Is there something I can do to "fix" this behaviour, or does anyone have a good way to handle these edge cases, or how to code if differently all together to avoid this issue?
This is clearly a browser issue, although i'm not sure what would be the expected bahaviour.
The problem is that when you have a radio group, the keyboard goes to the selected element. If this element is disabled, then the focus will jump the whole radio group even if the other one are not disabled.
One "fix" would be to avoid the problem by dissociating the radio buttons in two groups and relying on some javascript code to let them appear as a whole group. You can also reimplement the whole radio button feature by using aria role="radio" on 4 div elements.
It's also possible to ask and wait for the bug to be fixed.
I have seen it on several webpages (cannot recall where exactly atm) where I am able to check or uncheck checkboxes by clicking on the text in front of the checkbox. I know how to do it in JavaScript (create a span with onclick()) , but I want to know if there is any way I can do it without JavaScript.
You can achieve this functionality using label tag as given below.
<input type="checkbox" id="option">
<label for="option">Select this option</label>
I want to have a checked checkbox behave as an unchecked checkbox, and an unchecked checkbox behave as a checked checkbox. How can this be accomplished?
Context: In my template is a for loop that creates a checkbox for each filter condition. I want to show the user that the initial setting has all checkboxes checked, and they can uncheck them to exclude certain categories. The backend uses exclude statements, therefore it's necessary to invert the checkboxes.
Try the checked attribute
<input type="checkbox" name="vehicle" value="Car" checked> I have a car<br>
