c-sf-block.scss

// TODO: Reduce nesting further by splitting out more components.
//
// Theres quite a lot of nesting in here which makes parsing some segments difficult.
// Some of this is to deal with the fact that .c-sf-block can contain many .c-sf-block's and so is
// legitimate. A lot of these would ideally be their own components (eg the actions) however there
// is a lot of interdependancy of the elements because of COLLAPSIBLE vs SIMPLE vs default which
// makes this hard without fairly intensive rethinking of the HTML.
//
// However, the new classes adequately sanitise streamfield only CSS so am leaving this for
// now to avoid blocking the release of the new Streamfield. -@jonnyscholes

// TODO: Consider visually moving .c-sf-block__type and .c-sf-block__actions based on COLLAPSIBLE vs
// SIMPLE vs default using CSS only instead of moving HTML around. -@jonnyscholes
