The svg files were modified to remove the height and width attributes from the file per Sara Soueidan's advice in "Making SVGs Responsive With CSS".
In order to make an SVG fluid, the first logical thing to do is to remove the height and width attributes. When a fixed height and/or width is specified, the SVG is going to maintain that height/or width, thus restricting it from being fully responsive. You should, however, leave the viewBox attribute present. After removing the height and width, you can embed the SVG in one of several ways on the page.
A fill color was also added for each SVG. The originals are found as part of the Font-Awesome-SVG-PNG library on GitHub at
