Fixing spacing issues in SCSS files.

Again, I feel like this is pretty much de facto. The following examples
illustrate what I mean. The first is wrong, while the second is correct.

Example 1: footer{
Example 1:   border-top:3px solid #30add1;
Example 1: }

Example 2: footer {
Example 2:   border-top: 3px solid #30add1;
Example 2: }

See http://sass-lang.com/docs/yardoc/file.SASS_REFERENCE.html.
Utilizing what makes SCSS SCSS.

Sass is an extension of CSS3, adding nested rules, variables, mixins,
selector inheritance, and more. The following examples illustrate what
nesting means, which is what I have done. The 1st example can be written
as the 2nd, when utilizing SCSS.

Example 1: table.hl {
Example 1:   margin: 2em 0;
Example 1: }
Example 1:
Example 1: table.hl td.ln {
Example 1:   text-align: right;
Example 1: }

Example 2: table.hl {
Example 2:   margin: 2em 0;
Example 2:
Example 2:   td.ln {
Example 2:     text-align: right;
Example 2:   }
Example 2: }
