need some help wit ha tiny piece of js code

hi there,

I am trying to customize a theme and I'd like to hide comments and have them slide into view if someone clicks the show comments button.

so the comments are initially hidden via css: display:none;

after checkingn a few sites, this is not such a good idea, since users without js won't ever reach my comments.

the tutorial I use for hiding is this one:

then I found a suggested solution of hiding the comments via js so if a user has js turned of he will see the comments and those that have js will have to click to see them...

The suggested solution was:

If you are using JavaScript to show something, you should also use JavaScript to hide it

can someone help me out here with a line of code?

hiding with js also has the benefit of the hidden text getting indexed by google
