Special markup and classes

\n

Most Ionic markup works without changes. The combinations below are explicit opt-ins provided by the theme.

\n

Primary submit buttons

\n

Solid submit buttons use the Ionic color's contrast value for their foreground. Their directional edge treatment follows the iOS 27 prominent-button appearance and does not require an additional brightness color.

\n
<ion-button type="submit" color="primary">Submit</ion-button>\n<ion-button class="button-submit" fill="solid" color="primary">Continue</ion-button>
\n\n
\n
Preview
\nSubmit\nContinue\n
\n\n

Use .button-submit when the button needs the same treatment but cannot use type="submit".

\n

Preferred overlay actions

\n

For iOS alerts and action sheets, set role: 'preferred' on a button to give it a filled --ion-color-primary background and --ion-color-primary-contrast text and icons. While pressed, the background uses --ion-color-primary-shade. This is a theme convention using Ionic's custom button roles; it does not automatically select or invoke the action. Dismissal reports the role as preferred.

\n
buttons: [\n  { text: \'Cancel\', role: \'cancel\' },\n  { text: \'Continue\', role: \'preferred\' },\n];
\n\n

Buttons with no role or default keep the normal text color. cancel retains Ionic's cancellation behavior, selected remains a selection state, and destructive uses --ios-theme-destructive-color. An existing confirm role is not treated as preferred. Use preferred for the recommended action, not simply any action that confirms a choice.

\n

Floating iPad sheets

\n

Set expandToScroll: false on a sheet modal to use floating lower corners and a 20px bottom gap on iPad. Ionic then sizes the visible page at each breakpoint, so the theme can style it with CSS alone. Content scrolls within the current breakpoint; dragging the handle still resizes the sheet. With the default expandToScroll: true, the sheet keeps Ionic's bottom-attached layout and scroll-to-expand behavior.

\n

Tab bar position

\n

Add one of tab-bar-position-start, tab-bar-position-center, or tab-bar-position-end to an iOS ion-tab-bar to position the whole bar within its safe area. These classes work with both slot="top" and slot="bottom" and preserve the bar's width and press animation. Start and end follow the text direction (reversed in RTL). Without a class, the existing placement is unchanged.

\n
<ion-tab-bar slot="bottom" class="tab-bar-position-center">\n  <ion-tab-button tab="home">Home</ion-tab-button>\n  <ion-tab-button tab="settings">Settings</ion-tab-button>\n</ion-tab-bar>
\n\n

These classes do not reposition a separate ion-fab; leave room for it when choosing the bar's position.

\n

Foldable layouts

\n

To simulate the iPhone Duo layout on the web, add .ios-theme-enable-foldable to the active ion-app. Use body only when the application has no ion-app root:

\n
<ion-app class="ios-theme-enable-foldable">...</ion-app>
\n\n

The class reserves 80px on the physical right by default, matching the system navigation region measured in the iPhone Duo Simulator. The physical left defaults to 0px. Override --ios-theme-foldable-safe-area-left or --ios-theme-foldable-safe-area-right when simulating a different foldable layout.

\n

This keeps routers and component backgrounds full-viewport. ion-content moves its scroll foreground, ion-toolbar moves its container foreground, and ion-fab adjusts only when it is placed beside the system UI. The corresponding Ionic safe-area variable is reset inside those foreground components so descendants do not add the inset again.

\n

ion-menu, ion-modal, and ion-popover are handled as separate surfaces: their internal foreground components do not receive the main-page conversion and retain Ionic's standard safe-area handling. A menu presented beside the system UI is positioned after the corresponding inset; a menu from the opposite side is unchanged. Left and right remain physical coordinates in RTL, while Ionic's side="start" and side="end" values remain logical.

\n

The foldable values are web-layout simulation inputs. They are independent from Ionic's normal iPhone safe-area variables and do not change ordinary iPhone layouts unless the opt-in class is present.

\n

Two-line inset list items

\n

Place an unslotted ion-label immediately alongside an unslotted ion-note to render a two-line item. When using the iOS-style inset-list background, wrap the items in ion-item-group; keep ion-list-header outside the group.

\n
<ion-list inset="true">\n  <ion-list-header>\n    <ion-label>Connections</ion-label>\n  </ion-list-header>\n  <ion-item-group>\n    <ion-item>\n      <ion-label>Network &amp; internet</ion-label>\n      <ion-note>Mobile, Wi-Fi, hotspot</ion-note>\n    </ion-item>\n  </ion-item-group>\n</ion-list>
\n\n
\n
Preview
\n\n \n Connections\n \n \n \n Network & internet\n Mobile, Wi-Fi, hotspot\n \n \n\n
\n\n

Use slot="end" on ion-note when you want the standard trailing-note layout instead.

\n

Inset-list section headers

\n

Add .item-group-header to an ion-item-group to create the centered icon, title, and description used at the top of the component demo pages.

\n

This is an introductory group. Place regular list items in a separate ion-item-group that follows it.

\n
<ion-list inset="true">\n  <ion-item-group class="item-group-header">\n    <ion-item>\n      <ion-label>\n        <ion-icon name="list" style="background: var(--ion-color-primary)"></ion-icon>\n        <h2>Lists</h2>\n        <ion-text>Inset-list examples</ion-text>\n      </ion-label>\n    </ion-item>\n  </ion-item-group>\n  <ion-item-group>\n    <ion-item><ion-label>First item</ion-label></ion-item>\n  </ion-item-group>\n</ion-list>

Full-width segments

\n

Add .segment-style-glass to give a segment the same glass surface and selected indicator treatment as the tab bar. The class preserves the segment's existing dimensions and text colors, supports scrollable segments, and respects Ionic's public --background property.

\n
<ion-segment class="segment-style-glass" value="available">\n  <ion-segment-button value="available">Available</ion-segment-button>\n  <ion-segment-button value="away">Away</ion-segment-button>\n</ion-segment>
\n\n

For colored segments, use Ionic's color property (for example, color="primary" or color="secondary"). Ionic uses the palette's base color for the softly tinted track while keeping the selected surface and labels neutral. A surrounding colored toolbar only supplies colors when the segment has no color of its own. The optional moving glass inherits the selected surface color, and custom Ionic palettes work without additional registration.

\n

Add .segment-expand when segment buttons should divide the available width evenly. The class also changes the Liquid Glass effect sizing when registerSegmentEffect is used.

\n

Segments use a 32px minimum height in content and a 48px minimum height inside ion-toolbar. .segment-expand keeps the compact 32px layout in a toolbar. Compact segments retain Ionic's flat background and indicator colors; only the regular toolbar variant has a glass container and scales its outer container while pressed. Content and expanded segments keep their outer bounds. The optional moving glass lens is independent of the container's background.

\n
<ion-segment class="segment-expand" value="new">\n  <ion-segment-button value="new"><ion-label>New</ion-label></ion-segment-button>\n  <ion-segment-button value="replied"><ion-label>Replied</ion-label></ion-segment-button>\n</ion-segment>

Classic search bar in a condense header

\n

The theme gives iOS search bars the iOS 27 appearance by default. Add .searchbar-classic to the search field shown beneath a large title in an ion-header with collapse="condense". It uses the conventional filled iOS appearance and collapses with the large title instead of remaining in the fixed header.

\n

Place it in a toolbar with a color, such as color="light"; the classic background is derived from that color's contrast value.

\n

The example uses Ionic's standard collapsible large-title structure. Scroll the preview to collapse the large title and reveal the fixed header.

\n
<div class="ion-page">\n  <ion-header translucent="true">\n    <ion-toolbar color="light">\n      <ion-title>Search</ion-title>\n    </ion-toolbar>\n  </ion-header>\n  <ion-content color="light" fullscreen="true">\n    <ion-header collapse="condense">\n      <ion-toolbar color="light">\n        <ion-title size="large">Search</ion-title>\n      </ion-toolbar>\n      <ion-toolbar color="light">\n        <ion-searchbar class="searchbar-classic" placeholder="Filter results"></ion-searchbar>\n      </ion-toolbar>\n    </ion-header>\n    <ion-list inset="true">\n      <ion-item-group>\n        <ion-item><ion-label>Recent item 1</ion-label></ion-item>\n        <ion-item><ion-label>Recent item 2</ion-label></ion-item>\n        <ion-item><ion-label>Recent item 3</ion-label></ion-item>\n        <ion-item><ion-label>Recent item 4</ion-label></ion-item>\n        <ion-item><ion-label>Recent item 5</ion-label></ion-item>\n        <ion-item><ion-label>Recent item 6</ion-label></ion-item>\n        <ion-item><ion-label>Recent item 7</ion-label></ion-item>\n        <ion-item><ion-label>Recent item 8</ion-label></ion-item>\n        <ion-item><ion-label>Recent item 9</ion-label></ion-item>\n        <ion-item><ion-label>Recent item 10</ion-label></ion-item>\n      </ion-item-group>\n    </ion-list>\n  </ion-content>\n</div>

\n
\n\n

The .ion-page wrapper makes this embedded preview behave like a complete routed page. An application using ion-router-outlet normally receives that page container automatically. The inset list and its items only provide enough content to demonstrate scrolling; they are not required by .searchbar-classic.

\n

Search-bar toolbars

\n

Add .toolbar-searchbar when an ion-toolbar combines a search bar with start or end buttons. The class centers the slotted controls and adjusts the spacing around the search field.

\n
<ion-toolbar class="toolbar-searchbar">\n  <ion-buttons slot="start">\n    <ion-button>Cancel</ion-button>\n  </ion-buttons>\n  <ion-searchbar></ion-searchbar>\n</ion-toolbar>

Opting out

\n

Add .ios-theme-disabled to an individual Ionic component when it must retain Ionic's standard iOS styling.

\n

.ios26-disabled is deprecated but remains supported as an alias with the same behavior. Use .ios-theme-disabled for new code.

\n

Special markup and classes

\n

Most Ionic markup works without changes. The combinations below are explicit opt-ins provided by the theme.

\n

Primary submit buttons

\n

Solid submit buttons use the Ionic color's contrast value for their foreground. Their directional edge treatment follows the iOS 27 prominent-button appearance and does not require an additional brightness color.

\n
<ion-button type="submit" color="primary">Submit</ion-button>\n<ion-button class="button-submit" fill="solid" color="primary">Continue</ion-button>
\n\n
\n
Preview
\nSubmit\nContinue\n
\n\n

Use .button-submit when the button needs the same treatment but cannot use type="submit".

\n

Preferred overlay actions

\n

For iOS alerts and action sheets, set role: 'preferred' on a button to give it a filled --ion-color-primary background and --ion-color-primary-contrast text and icons. While pressed, the background uses --ion-color-primary-shade. This is a theme convention using Ionic's custom button roles; it does not automatically select or invoke the action. Dismissal reports the role as preferred.

\n
buttons: [\n  { text: \'Cancel\', role: \'cancel\' },\n  { text: \'Continue\', role: \'preferred\' },\n];
\n\n

Buttons with no role or default keep the normal text color. cancel retains Ionic's cancellation behavior, selected remains a selection state, and destructive uses --ios-theme-destructive-color. An existing confirm role is not treated as preferred. Use preferred for the recommended action, not simply any action that confirms a choice.

\n

Floating iPad sheets

\n

Set expandToScroll: false on a sheet modal to use floating lower corners and a 20px bottom gap on iPad. Ionic then sizes the visible page at each breakpoint, so the theme can style it with CSS alone. Content scrolls within the current breakpoint; dragging the handle still resizes the sheet. With the default expandToScroll: true, the sheet keeps Ionic's bottom-attached layout and scroll-to-expand behavior.

\n

Tab bar position

\n

Add one of tab-bar-position-start, tab-bar-position-center, or tab-bar-position-end to an iOS ion-tab-bar to position the whole bar within its safe area. These classes work with both slot="top" and slot="bottom" and preserve the bar's width and press animation. Start and end follow the text direction (reversed in RTL). Without a class, the existing placement is unchanged.

\n
<ion-tab-bar slot="bottom" class="tab-bar-position-center">\n  <ion-tab-button tab="home">Home</ion-tab-button>\n  <ion-tab-button tab="settings">Settings</ion-tab-button>\n</ion-tab-bar>
\n\n

These classes do not reposition a separate ion-fab; leave room for it when choosing the bar's position.

\n

Foldable layouts

\n

To simulate the iPhone Duo layout on the web, add .ios-theme-enable-foldable to the active ion-app. Use body only when the application has no ion-app root:

\n
<ion-app class="ios-theme-enable-foldable">...</ion-app>
\n\n

The class reserves 80px on the physical right by default, matching the system navigation region measured in the iPhone Duo Simulator. The physical left defaults to 0px. Override --ios-theme-foldable-safe-area-left or --ios-theme-foldable-safe-area-right when simulating a different foldable layout.

\n

This keeps routers and component backgrounds full-viewport. ion-content moves its scroll foreground, ion-toolbar moves its container foreground, and ion-fab adjusts only when it is placed beside the system UI. The corresponding Ionic safe-area variable is reset inside those foreground components so descendants do not add the inset again.

\n

ion-menu, ion-modal, and ion-popover are handled as separate surfaces: their internal foreground components do not receive the main-page conversion and retain Ionic's standard safe-area handling. A menu presented beside the system UI is positioned after the corresponding inset; a menu from the opposite side is unchanged. Left and right remain physical coordinates in RTL, while Ionic's side="start" and side="end" values remain logical.

\n

The foldable values are web-layout simulation inputs. They are independent from Ionic's normal iPhone safe-area variables and do not change ordinary iPhone layouts unless the opt-in class is present.

\n

When the app contains ion-tabs, foldable mode moves its iOS tab bar into the physical right-side reserved region and aligns it above the bottom safe area. The Ionic slot value does not select a different foldable position. The stable rail is icon-only, matching a four-tab SwiftUI TabView on iPhone Duo. While the user presses and drags across the rail, every icon-and-label tab reveals its label so the pending destination stays identifiable. The tab bar remains in the web layer and receives pointer input in the simulated system region. Use ion-menu when navigation should become a sidebar; foldable mode does not convert tabs into a menu.

\n

Two-line inset list items

\n

Place an unslotted ion-label immediately alongside an unslotted ion-note to render a two-line item. When using the iOS-style inset-list background, wrap the items in ion-item-group; keep ion-list-header outside the group.

\n

The .ion-page wrapper makes this embedded preview behave like a complete routed page. An application using ion-router-outlet normally receives that page container automatically. The inset list and its items only provide enough content to demonstrate scrolling; they are not required by .searchbar-classic.

Search-bar toolbars

\n

Add .toolbar-searchbar when an ion-toolbar combines a search bar with start or end buttons. The class centers the slotted controls and adjusts the spacing around the search field.

\n
<ion-toolbar class="toolbar-searchbar">\n  <ion-buttons slot="start">\n    <ion-button>Cancel</ion-button>\n  </ion-buttons>\n  <ion-searchbar></ion-searchbar>\n</ion-toolbar>

Opting out

\n

Add .ios-theme-disabled to an individual Ionic component when it must retain Ionic's standard iOS styling.

\n

.ios26-disabled is deprecated but remains supported as an alias with the same behavior. Use .ios-theme-disabled for new code.

\n
<ion-button>iOS 27 theme</ion-button> <ion-button class="ios-theme-disabled">Standard Ionic button</ion-button>

They are independent from Ionic's normal iPhone safe-area variables and do not change ordinary iPhone layouts unless the opt-in class is present. +When the app contains `ion-tabs`, foldable mode moves its iOS tab bar into the physical right-side reserved region and aligns it above the bottom safe area. The Ionic `slot` value does not select a different foldable position. The stable rail is icon-only, matching a four-tab SwiftUI `TabView` on iPhone Duo.
