Now defining margin instead of padding in ```/sass/base/_layout.scss``` so that the distance from
the navigation and article content scales nicely with smaller displays (phones, tablets).
Now setting colors ($nav-bg and navigation borders) in the appropriate file (
```sass/base/_themes.scss``` ).
Setting (curtailed) navigation bar specifications in the appropriate file (
```sass/partials/_navigation.scss``` )
Delleted color specifications in ```/sass/custom/_styles.scss``` which override end-user color
specifications in ```sass/custom/_colors.scss```; also removed navigation specifications from
here as they were placed in a better location - ```/sass/partials/_navigation.scss```.
changed width spec
changed navigation bar colors ```sass/base/_theme.scss``` to more closely match original
whitespace design
removed superfluous ```background-color``` spec from sass/partials/_navigation.scss
