oh geez...seems you're right...i haven't the slightest clue why. how worrisome... :\ i don't know css very well, but the sensitivity of the buttons is kind of weird--even in Chrome and on Opera you have to click directly on the text for them to work. i'll consider going back to old-fashioned links, i think. thanks for the heads up, much appreciated! ♥
HTML specs don't seem to like the idea of a link inside of a button, but, like quokka says, you could put the button inside of the anchor tags(even if it does work on Chrome). See here -> https://stackoverflow.com/questions/41275537/why-firexfox-and-ie-cannot-open-a-link-anchor-inside-a-button-button-tag You could also just ditch the button tags and style the anchors to give them the same look.
Buttons are really meant to be used if you're attaching them to a Javascript onclick event. But that would be complicating things more than is necessary for a page link...
your new diary layout is beautiful!
Thanks a lot! ^_^
