How to associate label with checkbox but not using "for=id" - html

Question

i have this code:
<li><input type="checkbox" id="checkboxThree" value="Alergia3" ><label for="checkboxThree">Alergia 1</label></li>
<li><input type="checkbox" id="checkboxFour" value="Alergia4"><label for="checkboxFour">Alergia 1</label></li>
<li><input type="checkbox" id="checkboxFive" value="Alergia5"><label for="checkboxFive">Alergia 1</label></li>
<li><input type="checkbox" id="checkboxSix" value="Alergia6" ><label for="checkboxSix">Alergia 1</label></li>
But I don't want to use "id" and "for" because I have to do other thing later and I can't use them. I have see this question: Possible to associate label with checkbox without using "for=id"? and I have triet what the first peson says:
<li><label ><input type="checkbox" name="Alergia1">Alergia 1</label></li>
<li><label ><input type="checkbox" name="Alergia2" >Alergia 1</label></li>
But It does not work either.
This is the entire project to see that it does not work:

So the first two checkboxes doesn't work.
Is there other way to do that? Thank you!

Answer 1

It doesn't seem to work for the first two "checkboxes" because putting the checkboxes in the label elements makes this CSS rule stop working:
ul.ks-cboxtags li input[type="checkbox"]:checked + label
That rule only applies to a checkbox followed by a label, not a label with a checkbox inside it.
If you're going to use the pattern with the checkbox inside the label, you're going to have to find a different way to do the styling. CSS isn't my strong suit, but as I understand it it's hard to style an element based on something inside that element. (There was once, briefly, a :contains pseudo-class, but it was never broadly supported because IIRC there were issues with performance.) This question's answers describe ways to do it, but unfortunately I think you're stuck with JavaScript if you do the containment.
