- Replace custom styles with the new variables throughout all stylesheets.
- This if the 1st PR as part of the of the Align components in Fleet UI with design system in Figma #539
- These changes replace all the color variables in /styles/var/colors.scss with new colors and naming convention used in Figma.
The goal of this PR was to insert new colors, remove legacy colors, and update only the styles accordingly. The Nunito Sans Italic font was also added.
Later PRs will include layout, copy, and style change to individual components. These later changes will more exactly resemble the current mockups.
- Replace uses of deprecated Bourbon helpers with raw CSS
- Add autoprefixer into the build chain to prefix the now removed helpers
This process was achieved by running through each of the deprecation warnings and using the following bash function to replace it in all files:
```
function bourbon-deprecate() {
grep -rl "@include $1" ./frontend --exclude-dir=.git | xargs sed -i '' -E "s/@include $1[(](.*)[)]/$1: \1/g"
}
```
For some helpers, this did not result in valid CSS, so manual modifications were made.
Closes#1189#1274
