feat(content): add recipe and tokens by thetaPC · Pull Request #31095 · ionic-team/ionic-framework

thetaPC · 2026-04-24T23:04:37Z

Issue number: resolves internal

What is the current behavior?

ion-content does not fragment styles based on themes. All 3 themes share one style. However, it's not configured to the Modular Ionic.

What is the new behavior?

Defined TypeScript Interface: Renamed content-interface.ts to content.interfaces.ts and added IonContentRecipe type.
Defined Theme Defaults: Added per-theme token defaults in ios, md, and ionic theme files.
Internal Variable Prefix: Renamed --offset-top / --offset-bottom to --internal-offset-top / --internal-offset-bottom to clearly separate them from the public CSS API.
CSS Logical Properties for RTL: Replaced physical-property RTL selectors on .transition-effect and .transition-shadow with the position-horizontal mixin.
Removed dead property: Dropped -webkit-overflow-scrolling: touch from styles as this property has been a no-op since iOS 13.
Updated Tests: Added unit specs for transitionShadow (present in ios mode, absent in md mode) and the getScrollElement() / getBackgroundElement() element ref methods.
New utility: Replaced inline new Promise((resolve) => componentOnReady(...)) patterns with a shared waitForComponent helper, reducing boilerplate and improving type safety.
Split default vs. semantic tokens: Nested background/color under default and added a semantic.default group.

Does this introduce a breaking change?

Yes
No

This PR introduces breaking changes to how ion-content is styled.

Migration Path:

CSS Variable Replacements: --background and --color have been removed. Use the new token structure:

--background -> IonContent.default.background
--color -> IonContent.default.color

--padding-* is still supported. .ion-padding, .ion-padding-* classes in css/padding.scss set --padding-* directly on the host. ion-content continues to honor those values (falling back to the new token when unset). Existing usage of the utility classes and direct --padding-* overrides will keep working.

New code is encouraged to use the token-based API instead:

--padding-top -> IonContent.padding.top
--padding-end -> IonContent.padding.end
--padding-bottom -> IonContent.padding.bottom
--padding-start -> IonContent.padding.start

Note: core/api.txt only lists the new --ion-content-padding-* variables. The --padding-* overrides remain functional but are no longer part of the documented public API.

If per-component customization is needed, the CSS variables can be used directly.

--background -> --ion-content-background
--color -> --ion-content-color
--padding-top -> --ion-content-padding-top
--padding-end -> --ion-content-padding-end
--padding-bottom -> --ion-content-padding-bottom
--padding-start -> --ion-content-padding-start

Internal-only variables (no replacement): The following CSS variables were previously documented @props on ion-content and have been renamed to the --internal-* namespace, removing them from the public API:

--keyboard-offset -> --internal-keyboard-offset
--offset-top      -> --internal-offset-top
--offset-bottom   -> --internal-offset-bottom

These are managed by ion-content itself (keyboard avoidance and header/footer offsets) and were never intended for consumer override. There is no replacement - any code that was setting them directly should be removed.

Theme classes: Remove any instances that target the theme classes: ion-content.md, ion-content.ios.

Other information

Previews:

The framework (Angular, React, Vue) test apps are not being styled correctly anymore because the new tokens are not being passed to them. This is expected until we can export the tokens as mentioned in the design doc. The functionality in those test apps are still working.

Created a util for this since a lot of components are using the same code

Looking good! Minor changes requested.

+:host(.ion-color) .inner-scroll {
+  background: color.current-color(base);
+  color: color.current-color(contrast);


The foreground color should only be used when it's a text-only component. So if setting color on the content changes its text but not its background. You can look at ion-text as an example of a text-only component that uses color. Since we are changing the background on this component, contrast is the correct text value.

Maybe we should add this on to FW-7295?

Should any component that supports semantic color also support hue?

Discussing this offline. If work is needed, then we will add it through another ticket.
