How do you test if a div has a certain css style in rspec/capybara?

Question

How do you test if a div tag has a certain css style? I\'m trying to test if it has display:none; or display:block.

I tried the following

Answer 1

My way to ensure that element have a certain class:

let(:action_items) { page.find('div.action_items') }

it "action items displayed as buttons" do
  action_items.all(:css, 'a').each do |ai|
    expect(ai[:class]).to match(/btn/)
  end
end

or smthing like this

expect(ai[:style]).to match(/color: red/)
