Acceptance criteria

• All SCSS files have been removed from the component(s) directory
• All SCSS overrides have been removed from the Amsterdam theme
• Changelog is updated
• [ ] Breaking changes are identified and broadcast to consumers
• [ ] Any dependent components are identified in a new issue

Checklists

No modifier classes removed

General

• Output CSS matches the previous CSS (works as expected in all browsers)
• Rendered className(s) read as expected in snapshots and browsers
  - [ ] Checked component playground

Unit tests

• shouldRenderCustomStyles() test was added and passes with parent component and any nested childProps (e.g. tooltipProps)
• Removed any mount()ed snapshots in favor of render() or a more specific assertion

Sass/Emotion conversion process

• Converted all global Sass vars/mixins to JS (e.g. $euiSize to euiTheme.size.base)
• Removed or converted component-specific Sass vars/mixins to exported JS versions
• Listed var/mixin removals in changelog
• Removed component from src/components/index.scss
• Deleted any src/amsterdam/overrides/{component}.scss files (styles within should have been converted to the baseline Emotion styles)
• [ ] Ran yarn compile-scss to update var/mixin JSON files
• [ ] Simplified calc() to mathWithUnits if possible (if mixing different unit types, this may not be possible)
• [ ] Added an @warn deprecation message within the global_styling/mixins/{component}.scss file

CSS tech debt

• Wrapped all animations or transitions in euiCanAnimate
• Used gap property to add margin between items if using flex
• Converted side specific padding, margin, and position to -inline and -block logical properties (check inline styles as well as CSS)

DOM Cleanup

• [ ] Did NOT remove any block/element classNames (e.g. euiComponent, euiComponent__child) deleted .euiDataGridHeaderCell__content div wrapper from header control cells
• [ ] SEARCH KIBANA FIRST: Deleted any modifier classNames or maps if not being used in Kibana. - none deleted

Kibana due diligence

• Pre-emptively check how your conversion will impact the next Kibana upgrade. This entails searching/grepping through Kibana (excluding **/target, **/*.snap, **/*.storyshot for less noise) for eui{Component} (case sensitive) to find:
• Any test/query selectors that will need to be updated
• Any Sass or CSS that will need to be updated, particularly if a component Sass var was deleted
• Any direct className usages that will need to be refactored (e.g. someone calling the euiBadge class on a div instead of simply using the EuiBadge component)

Extras/nice-to-have

• Reduced specificity where possible (usually by reducing nesting and class name chaining)
• [ ] Documentation pass:
• [ ] Check for issues in the backlog that could be a quick fix for that component
• [ ] Optional component/code cleanup: consider splitting up the component into multiple children if it's overly verbose or difficult to reason about
