slight CSS refactor; new hsla fallback colors
one missing fallback color; fixed nav hover color bug
CSS colors stored in front matter
- YAML now contains all of the colors in hex and hsla format in the front matter
- All colors are now referenced in the CSS document via liquid tags
- No changes in style or color in the document
