This is a commandline tool to grab correctly-cropped screenshots of the same HTML element found in many copies of the same html file in multiple subdirectories, and drop these shots in each directory.
Run
npm install -g partlyhuman/batch-capture
from the command line.
Run batch-capture, giving it options and a directory root
to start looking for files in. You often use . for the current
directory.
Run with no arguments or batch-capture --help to see all available
options.
