Global template 

Better to be really specific and say `background-color` as saying `background` is only unnecessarily increasing the specificity. See: https://github.com/westfield/css_guidelines#writing-css

>> It might be tempting to use declarations like background: red; but in doing so what you are actually saying is ‘I want no image to scroll, aligned top-left, repeating X and Y, and a background colour of red’. Nine times out of ten this won’t cause any issues but that one time it does is annoying enough to warrant not using such shorthand. Instead use background-color: red;.
