CMS Button + Date cell Changes

[theresastone]

• when row to small, the button should wrap
• so the button doesn't have left margin when displayed in next row, give headline margin
• added row-gap class, to have space between headline and button on mobile
• when screen is small, the date cells shouldn't wrap
