Thanks for posting back so quickly!
I followed your first step, adding the following to the css:
.content{display:none;}
.menucontent{display:none;}
As promised, the accordion content did not display. But also, the post title headings became static. They no longer linked to the post content; and did not appear with the a:link styling given in my css. There’s no navigation to the content at all.
Do steps 2 and 3 resolve the above? I have made a lot of changes to my .css over time and I don’t want to dig in too much further (I’m no pro with .js files) here if I have some other underlying css stuff to tailor.
Thanks again.
