By their very nature, styles further down a cascading style sheet (CSS file to you and me) override equivalent styles higher up (unless styles higher up are more specific). We can therefore set base styles at the beginning of a style sheet, applicable to all versions of our design (or at least providing our 'base' experience), and then override relevant sections with media queries further on in the document.
