Toggle Diffs about wg21

I handle this by having a style block at the top of my document containing among other things:

<style>
label { font-weight: bold; }

#hide_rm:checked ~ .wording .rm {
  display: none;
}

.wording {
  margin-left: 40px;
}
.wording .instruction {
  font-size: large;
  margin-left: -40px;
}
.wording .grammar {
  padding-left: 4em;
  word-spacing: .25em;
}
</style>

And a then in the Proposed Wording section I have

# Proposed Wording

```{=html}
<label for=hide_rm>Hide removed wording:</label>
<input type="checkbox" id="hide_rm"></input>
```

::: wording

[Modify [location.name]{.sref} as follows:]{.instruction}

[1]{.pnum} Make it [fail]{.rm}[work]{.add}.
