Answer 1

It’s as if you haven’t made anything up yet, but the grid itself seems to be arranged correctly!

Answer 2

hmm, judging by the title in the codepen, you are using html5 layout, but where <header> <footer> <nav>are the other elements? you can also use divs with the jumbotron class for the slider in bootstrap
