I'm an educator (and beginning programmer) and am really excited about the 
potential of using Pollen for several projects.

I've read through the Pollen documentation thoroughly, and am unable to 
find any examples that cover what I need. I also have zero experience in 
Racket.

I'm trying to build Tufte-style margin notes 
<https://edwardtufte.github.io/tufte-css/> using Pollen (although if I can 
get this to work I will be able to use it for several other use cases). The 
markup I would like is like this:

<label for="mn-demo" class="margin-toggle">&#8853;</label>
<input type="checkbox" id="mn-demo" class="margin-toggle"/>
<span class="marginnote">
This is a margin note. Notice there isn’t a number preceding the note.
</span>


This is what I have so far:
 
#lang pollen

◊(define (margin . notes) `(span ((class "marginnote")) ,@notes))

Lorem◊margin["mn-demo"]{This is a margin note. Notice there isn’t a number 
preceding the note.} ipsum dolor sit amet, consectetur adipiscing elit.

There are two things I'm struggling with. First, I know how to *nest *the 
span with class "marginnote" inside another element. However, I don't know 
how to place two elements *before* it. (I've wasted a lot of time trying to 
make this work.)

Second, each margin note needs its own unique ID. So I want to pass this id 
(in this case "mn-demo") as an argument to the function. However, again I 
can't quite work out how to make this happen. In the Pollen documentation 
there are lots of examples using key-value pairs, but in this case the key 
is redundant. It would be redundant to have to type the same key every time 
I call the function, like this: [#:id "mn-demo"] It's much neater to just 
have ["mn-demo"].

I would be really grateful if anyone can help me, as I've come to the ends 
of what I can achieve on my own!
