<div class="container iframe-container">

        <style>
           body { background-color: #000111; } .form-horizontal .control-label { font-style: normal; } ...
        </style>

basically I want to check if the background is #000111

Answer 1

Finally found the answer:

within_frame('wrapper') do
   color = find('body').native.css_value('background-color')
   expect(color).to eq('rgba(0, 1, 17, 1)')
end
