I need to know what I can add to my functions.php (or another method?) to make the metabox for entering the Excerpt (on the Post/Page Add/Edit screen) larger as a default. We use that box for a specific purpose but as it only shows three lines - and the entered text is more than three lines - it means scrolling that we'd like to eliminate.
How can I make the size of that box be something like 10 lines?
Thanks for any advice!
