when providing snapage with --viewports, -v or --style, -s,
snapage-cli will coerece the input to suit the expected input by snapage.
when providing styles - it will be applied to the body element (future release will include class based css).
the provided styles should be sperated by a colon (:) and different styles separated by semi-colon (;).
for example: snapage https://google.com -s 'border: 1px solid red; filter: scale(1.1);'
when providing viewport sizes (as opposed to device name such as iPad Pro) - use a x seperator between width and height.
for example: snapapage https://github.com -v '800x600' '1240x1080' 'iPhone X'
