position elements on the page (all elements should be positioned well)

• [x] StockChart and StockNews are appropriate sizes for multiple window sizes.
• [x] Content is centered rather than up against the left edge.
• [x] Nav is centered rather than against the left and right edges.

Set #content to:

display: flex;
justify-content: center;

and .nav to min-width:900px

Everything looks good until the window gets narrower than 900px; then it cuts off the right and left parts of the screen.

Fine for now.
