combining numerous css selectors fails - html

Question

I have a detailed css radio button I would like to use 45 times on the same page.
The css is a little beefy so it make no sense to recreate the entry 45 times.
But, when I try and combine multiple id tags, I get numerous errors (not displaying correctly)
HTML:
<div class="pcontainer">
<section class="pmain">
<div class="rblock">
<div class="squared1">
<input type="checkbox" value="None" id="squaredOne" name="check" />
<label for="squared1"></label>
</div>
</div>
</section>
<nav class="pright">
<div class="rblock">
<div class="squared2">
<input type="checkbox" value="None1" id="squaredOne" name="check" />
<label for="squared2"></label>
</div>
</div>
</nav>
....squared36
</div>
CSS:

How do I combine numerous CSS selectors?
Is there a dynamic method in CSS?

Answer 1

You wrote wrong css selector:
Use, for example:
.squared1 label, squared2 label
instead of
.squared1, squared2 label
Commas allows you to write multiple selector, but all of them must be complete
