Separating most LESS files into 2 ResourceLoader modules and a common
folder:
- skins.vector.styles
- skins.vector.styles.legacy
- common
This changes aims to clearly separate the old (“legacy”), the new
(“modern”) and the common styles which were previously all placed under
`skins.vector.styles/`.
Inside each directory are separate folders for `layouts` and
`components`.
The entry files, `skin.less` and `skin-legacy.less` are moved into the
specific folders and a third, `common.less` entry file is created that
contains the common imports for both old and new Vector.
Aliases have been added to the Storybook Webpack config to avoid adding
the story file changes to this patch. Images coming from CSS `url()`'s
have also been temporarily disabled in Storybook until Storybook can be
upgraded to use Webpack 5, and use array values for aliases, in a
follow-up patch.
This patch also slightly changes a footer layout specific rule so that
existing `padding` remains unchanged in rendering due to new common and
component structure.
