Take screenshots at different viewport sizes using CasperJS
# Takes provided URL passed as argument and make screenshots of this page with several viewport sizes.
# These viewport sizes are arbitrary, taken from iPhone & iPad specs, modify the array as needed
# Original gist by nhoizey:
# Usage:
# $ casperjs [--atf] [--url=URL]
# with SlimerJS - it has better feature support than the default PhantomJS
# $ casperjs --engine=slimerjs [--atf] [--url=URL]

You can’t perform that action at this time.
