 Plan: Layout and design each component for the smallest screen size first, then add more elements to each one as the size increases.
+    - “when in doubt, just remove.” (or place in a menu out of main view)
+    - It makes no sense to target individual devices anymore. Instead, add breakpoints where your design breaks. 
+    If you start with your design for the smallest device and start to drag your browser window wider, when do the lines become too long to read comfortably? 
+    When could you make better use of the screen? That is the point at which to add a Media Query and write some additional CSS.
     - NAV For example a menu can be fully shown as icons in a larger size but might be behind another click in smaller
     - Functionality: figure out what the minimum most important things to show at small size then add more "optional" stuff as it increases
         - Grid: show the Name column first and selector, then add the most relevant columns in order of relevancy
