Circumvent id selectors in a checkbox hack - html

Question

I've posted about this project before. Twice, actually. And while the answers have helped me to better understand my situation, they haven't really been applicable to my situation. I blame myself because I was posting a skeletal version of the final code which didn't fully illustrate what I needed to accomplish.
Essentially: I need to integrate a relatively simple checkbox hack into a CMS, but the CMS strips id selectors. Hence, code that ought to look something like this:
<input type="checkbox" name="thisisaname" id="thisisanid"><label class="thisisanid" for="thisisanid">Type 1</label>
...ends up like this:
<input type="checkbox" name="thisisaname"><label class="thisisanid" for="thisisanid">Type 1</label>
Predictably, this breaks everything, and ostensibly any adaptation appears to be impossible. There is no CMS-specific alternative like ClientID=. Neither jQuery nor JavaScript are available to me (they're also stripped out by the CMS).
It's a case of something being extraordinarily simple to do, but being constrained by a CMS that multiplies the difficulty to the point where I'm uncertain if it's even possible. I am not a CSS maven. I know it only as much as I need to do these little projects for a few friends, and I apologize for posting about this yet again, but it's driving me crazy not knowing if this is something which ought to be shelved.
This is the code. Obviously, it's sloppy and it isn't in its fully-styled form, but it's close enough that I think it's a better example than what I've posted in the past:

I am in a quandary. I'm not very knowledgeable in CSS, and this CMS (which I must use, unfortunately) makes even the easiest of tasks inordinately difficult. Here's what I've tried:
Using nth-child / nth-of-type selectors: I was given this idea by
Temani Afif. This solution is elegant and I loved it, but
unfortunately, because of what the code will be used for, the
structure will vary often.
Placing the input above the labels: I've been advised to look
into this, but I can't find any information on how to properly code
with the input above the label, so I'm unsure if it can be used in this
situation.
I thought about mimicking the behavior I want using
[attribute|=value] selectors instead of id, but I haven't been
able to get it to work. I don't know, though, whether I'm being
limited by the code or my own incompetence, so I'm unsure if it's
something worth looking into further.
So… Is there a recommended means of overcoming the id= limitations I've missed in my research?
FWIW, the purpose of this is to create a simple(ish) code where it's easy to append the INFO CARD part of the code as many times as needed to edit this for sorting movies/books/other information of that nature, while maintaining the ease at which one can change the figure class=.

Answer 1

The issue here is the rather limited way in which the for attribute works inside a <label> - it looks for a form control with the corresponding id. (Only the id will do - no other attribute.)
If it cannot find one, then no form control ends up being associated with the <label>... consequently, the checkbox hack, which relies on the for attribute working, cannot produce the intended effect.
Since we can't add the id to the checkbox in the document's initial mark up, why not, instead, add the id to the checkbox dynamically, by accessing the Document Object Model (DOM)?
This is easily done in a single line:
document.querySelector('[name="thisisaname"]').id = 'thisisanid';
See the Working Example below, noting that the id is not present in the initial markup:
document.querySelector('[name="thisisaname"]').id = 'thisisanid';
label {
cursor: pointer;
}
label:hover {
font-weight: bold;
text-decoration: underline;
}
input[type=checkbox],
input[type=checkbox] + p {
opacity: 0;
}
input[type=checkbox] + p {
transition: opacity 1s linear;
}
input[type=checkbox]:checked + p {
opacity: 1;
}
<label class="thisisanid" for="thisisanid">Click Me</label>
<input type="checkbox" name="thisisaname">
