Main CSS Changes

1. Small Grey Icons on 'Our Approach'
On the 'Our Approach' page, I included small icons using a Summary Block. I disabled the links (normally a large picture pops up on click), added padding to make them smaller, and also reduced the opacity to make them lighter.
Note: On a mobile device, these icons disappear and are replaced with bullet points. This is because these icons would not otherwise fit properly on the screen. This was the most unobtrusive way to do it without affecting other components.
IMPORTANT: If you want to edit this block, please try not to delete this block. If this block was deleted, check out this tutorial on how to get it back again. If you actually do want to delete the block, that's fine. It won't affect anything else. Just follow these steps.

2. Quote Block
Added a grey border and a little quote symbol at the top for "text quote" blocks. 

There are 3 kinds of quotes: 
A. Regular text (You just select a text block and manually add quotes)
B. Text Quotes (You start off with a text block, and then select Quote under the dropdown menu here
C. Quote Blocks

Basically, I made CSS changes so that "Text Quotes" look identical to "Quote Blocks".

3. Left & Right Page Content Padding
I added padding to the left and right of the page content.

4. Page Border
I added a grey page border on regular pages.
There are no page borders on index pages, but there is a grey line for the "preFooter" above the social media icons at the bottom of the screen. 

5. Footer
Removed the footer

6. Horizontal Line
Reduced the spacing above and below 

7. Header fonts
On a mobile device, I centered all headers and made the banner header font heavier
