I've done something... not sure what... and now everything on this site is way bigger than it used to be. Too big. It's only this site, so I guess it's something I did here? And it happened when I was messing around with the formatting on a new post, so possibly that had something to do with it? Help?
Huh. The browser zoom didn't work, but I restarted the computer and that did. So - thanks! Problem solved!
Google Chrome also as a zoom screen size option if anyone is using it: click on the three bars to the right side of menu bar (below the tabs, and above the bookmarks). The same option allows you to open an incognito window that comes in handy if you've used up your monthly free allotment of the WA Po or NYT news articles.
