Dear Tom,
1). Now I understood the second part of the question, sorry :) You want the mouse-over menu items to be of different tone than the original state? At the moment the theme (by design) makes the mouse-over items completely untransparent and does not change the colour. If you want the mouse-over items to change the tone, you’ll need to insert the following css code into «style.css»:
#nav-secondary .middle-menu-container li:hover { background-color: #000000 !important; }
instead of the six zeroes, you can insert any tone you want in the hex format.
2). Ah sorry I forgot to edit that in the original response! Instead of
please put
3). The date’s class is «.meta-date», and the comments have the class «.meta-comment-count»
4). This is not an Origami theme issue, yet anyways: if you go to «Settings — Discussion» section of the admin menu, you can un-check the «Allow people to post comments on new articles» option, which should turn off comments for all posts and pages, unless overridden by the individual page/post settings (there is a «Discussion» box underneath the text editor area if you edit a page or a post; if it does not appear, you should open the «Screen Options» tab on the top right and tick the «Discussion» option).
Hope this helps!
Sincerely,
Andrew | Satori
