rspec - capybara within :css syntax meaning -


i'm working on fixing specs, , have found piece of syntax nobody seems know represents.

in capybara suite there multiple occurrences of:

within(:css, '#foo') do

by removing :css have found functionally identical within('#foo') do

is there difference? other symbols can passed in first parameter within?

after following @andrey botalov's link, have found explains kind of selector being input within block.

in case, capybara.default_selector set :css, :css default. other option listed :xpath
