I thought I would have a look at spellcheck.html. I have updated the images as per my files, and have started working through the text.
One item that I (personally) think could be changed is the style <span class="menuitem">.
I don't know how others feel but I find that, as this is used to differentiate the text contained within the span from the surrounding text, there is not enough of a contrast between the two styles, and perhaps more emphasis should be applied to the referenced text.

I realise that if I play around with the properties of 'menuitem' in the style sheet this will affect the whole book so it needs to be something that works for all.
I will leave it as it is until I have heard what others think.
