Ionic Framework provides a set of CSS utility classes that can be used on any element in order to modify the text, element placement or adjust the padding and margin.
important
If your app was not started using an available Ionic Framework starter, the stylesheets listed in the optional section of the global stylesheets will need to be included in order for these styles to work.

Responsive Text Classes
All of the text classes listed above have additional classes to modify the text based on the screen size. Instead of text- in each class, use text-{breakpoint}- to only use the class on specific screen sizes, where {breakpoint} is one of the breakpoint names listed in Ionic Breakpoints.
The table below shows the default behavior, where {modifier} is any of the following: left, right, start, end, center, justify, wrap, nowrap, uppercase, lowercase, or capitalize, as they are described above.
.ion-text-{modifier} Applies the modifier to the element on all screen sizes. .ion-text-sm-{modifier} Applies the modifier to the element when min-width: 576px. .ion-text-md-{modifier} Applies the modifier to the element when min-width: 768px. .ion-text-lg-{modifier} Applies the modifier to the element when min-width: 992px. .ion-text-xl-{modifier} Applies the modifier to the element when min-width: 1200px. Float
The float CSS property specifies that an element should be placed along the left or right side of its container, where text and inline elements will wrap around it. This way, the element is taken from the normal flow of the web page, though still remaining a part of the flow, contrary to absolute positioning.

.ion-float-left float: left The element will float on the left side of its containing block. .ion-float-right float: right The element will float on the right side of its containing block. .ion-float-start float: left / float: right The same as float-left if direction is left-to-right and float-right if direction is right-to-left. .ion-float-end float: left / float: right The same as float-right if direction is left-to-right and float-left if direction is right-to-left. Responsive Float Classes
All of the float classes listed above have additional classes to modify the float based on the screen size. Instead of float- in each class, use float-{breakpoint}- to only use the class on specific screen sizes, where {breakpoint} is one of the breakpoint names listed in Ionic Breakpoints.
The table below shows the default behavior, where {modifier} is any of the following: left, right, start, or end, as they are described above.
.ion-float-{modifier} Applies the modifier to the element on all screen sizes. .ion-float-sm-{modifier} Applies the modifier to the element when min-width: 576px. .ion-float-md-{modifier} Applies the modifier to the element when min-width: 768px. .ion-float-lg-{modifier} Applies the modifier to the element when min-width: 992px. .ion-float-xl-{modifier} Applies the modifier to the element when min-width: 1200px. Display
The display CSS property sets whether an element is treated as a block or inline box and the layout used for its children, such as flow layout, grid or flex. It can also be used to completely hide an element from the layout.
Ionic provides the following utility classes for display:
.ion-display-none display: none Turns off the display of an element so that it has no effect on layout (the document is rendered as though the element did not exist). .ion-display-inline display: inline The element behaves as an inline element that does not create line breaks before or after itself. .ion-display-inline-block display: inline-block The element behaves as a block element that flows with surrounding content as if it were a single inline box. .ion-display-block display: block The element behaves as a block element, creating line breaks both before and after itself when in the normal flow. .ion-display-flex display: flex The element behaves like a block element and lays out its content according to the flexbox model. .ion-display-inline-flex display: inline-flex The element behaves like an inline element and lays out its content according to the flexbox model. .ion-display-grid display: grid The element behaves like a block element and lays out its content according to the grid model. .ion-display-inline-grid display: inline-grid The element behaves like an inline element and lays out its content according to the grid model. .ion-display-table display: table The element behaves like an HTML <table> element. It defines a block-level box. .ion-display-table-cell display: table-cell The element behaves like an HTML <td> element. .ion-display-table-row display: table-row The element behaves like an HTML <tr> element. Responsive Display Classes
All of the display classes listed above have additional classes to modify the display based on the screen size. Instead of display- in each class, use display-{breakpoint}- to only use the class on specific screen sizes, where {breakpoint} is one of the breakpoint names listed in Ionic Breakpoints.
The table below shows the default behavior, where {modifier} is any of the following: none, inline, inline-block, block, flex, inline-flex, grid, inline-grid, table, table-cell, table-row, as they are described above.
.ion-display-{modifier} Applies the modifier to the element on all screen sizes. .ion-display-sm-{modifier} Applies the modifier to the element when min-width: 576px. .ion-display-md-{modifier} Applies the modifier to the element when min-width: 768px. .ion-display-lg-{modifier} Applies the modifier to the element when min-width: 992px. .ion-display-xl-{modifier} Applies the modifier to the element when min-width: 1200px.

Flexbox properties are divided into two categories: container properties that control the layout of all flex items, and item properties that control individual flex items. See Flex Item Properties for item-level alignment.
Align ItemsThe align-items CSS property sets the align-self value on all direct children as a group. In flexbox, it controls the alignment of items on the cross axis. In grid layout, it controls the alignment of items on the block axis within their grid areas.
Ionic provides the following utility classes for align-items:
.ion-align-items-start align-items: flex-start Items are packed toward the start on the cross axis. .ion-align-items-end align-items: flex-end Items are packed toward the end on the cross axis. .ion-align-items-center align-items: center Items are centered along the cross axis. .ion-align-items-baseline align-items: baseline Items are aligned so that their baselines align. .ion-align-items-stretch align-items: stretch Items are stretched to fill the container. Align Content
The align-content CSS property sets the distribution of space between and around content items along a flexbox's cross axis, or a grid or block-level element's block axis.
This property has no effect on single line flex containers (i.e., ones with flex-wrap: nowrap).
Ionic provides the following utility classes for align-content:
.ion-align-content-start align-content: flex-start Lines are packed toward the start of the cross axis. .ion-align-content-end align-content: flex-end Lines are packed toward the end of the cross axis. .ion-align-content-center align-content: center Lines are centered along the cross axis. .ion-align-content-stretch align-content: stretch Lines are stretched to fill the container. .ion-align-content-between align-content: space-between Lines are evenly distributed on the cross axis. .ion-align-content-around align-content: space-around Lines are evenly distributed with equal space around them. Justify Content
The justify-content CSS property defines how the browser distributes space between and around content items along the main axis of a flex container and the inline axis of grid and multi-column containers.
Ionic provides the following utility classes for justify-content:
.ion-justify-content-start justify-content: flex-start Items are packed toward the start on the main axis. .ion-justify-content-end justify-content: flex-end Items are packed toward the end on the main axis. .ion-justify-content-center justify-content: center Items are centered along the main axis. .ion-justify-content-around justify-content: space-around Items are evenly distributed on the main axis with equal space around them. .ion-justify-content-between justify-content: space-between Items are evenly distributed on the main axis. .ion-justify-content-evenly justify-content: space-evenly Items are distributed so that the spacing between any two items is equal. Flex Direction
The flex-direction CSS property sets how flex items are placed in the flex container defining the main axis and the direction (normal or reversed).
Ionic provides the following utility classes for flex-direction:
.ion-flex-row flex-direction: row Items are placed in the same direction as the text direction. .ion-flex-row-reverse flex-direction: row-reverse Items are placed in the opposite direction as the text direction. .ion-flex-column flex-direction: column Items are placed vertically. .ion-flex-column-reverse flex-direction: column-reverse Items are placed vertically in reverse order. Flex Wrap
The flex-wrap CSS property sets whether flex items are forced onto one line or can wrap onto multiple lines. If wrapping is allowed, it sets the direction that lines are stacked.
Ionic provides the following utility classes for flex-wrap:
.ion-flex-nowrap flex-wrap: nowrap Items will all be on one line. .ion-flex-wrap flex-wrap: wrap Items will wrap onto multiple lines, from top to bottom. .ion-flex-wrap-reverse flex-wrap: wrap-reverse Items will wrap onto multiple lines, from bottom to top. Responsive Flex Container Classes
All of the flex container classes listed above have additional classes to modify the properties based on the screen size. Instead of the base class name, use {property}-{breakpoint}-{modifier} to only use the class on specific screen sizes, where {breakpoint} is one of the breakpoint names listed in Ionic Breakpoints.
The table below shows the default behavior, where {property} is one of the following: justify-content, align-content, align-items, flex, or flex-wrap, and {modifier} is the corresponding value as described above.
.ion-{property}-{modifier} Applies the modifier to the element on all screen sizes. .ion-{property}-sm-{modifier} Applies the modifier to the element when min-width: 576px. .ion-{property}-md-{modifier} Applies the modifier to the element when min-width: 768px. .ion-{property}-lg-{modifier} Applies the modifier to the element when min-width: 992px. .ion-{property}-xl-{modifier} Applies the modifier to the element when min-width: 1200px. Deprecated Classes
Deprecation Notice
The following classes are deprecated and will be removed in the next major release. Use the recommended .ion-flex-* classes instead.
.ion-nowrap Items will all be on one line.
.ion-flex-nowrap instead. .ion-wrap Items will wrap onto multiple lines, from top to bottom.
.ion-flex-wrap instead. .ion-wrap-reverse Items will wrap onto multiple lines, from bottom to top.
.ion-flex-wrap-reverse instead.
Flex item properties control how individual flex items behave within their flex container. See also: Flex Container Properties for container-level alignment.
Align SelfThe align-self CSS property overrides a grid or flex item's align-items value. In grid, it aligns the item inside the grid area. In flexbox, it aligns the item on the cross axis.
The property doesn't apply to block-level boxes, or to table cells. If a flexbox item's cross-axis margin is auto, then align-self is ignored.
Ionic provides the following utility classes for align-self:
.ion-align-self-start align-self: flex-start Item is packed toward the start on the cross axis. .ion-align-self-end align-self: flex-end Item is packed toward the end on the cross axis. .ion-align-self-center align-self: center Item is centered along the cross axis. .ion-align-self-baseline align-self: baseline Item is aligned so that its baseline aligns with other item baselines. .ion-align-self-stretch align-self: stretch Item is stretched to fill the container. .ion-align-self-auto align-self: auto Item is positioned according to the parent's align-items value. Flex
The flex CSS property is a shorthand property for flex-grow, flex-shrink and flex-basis. It sets how a flex item will grow or shrink to fit the space available in its flex container.
Ionic provides the following utility classes for flex:
.ion-flex-1 flex: 1 Item grows and shrinks equally with other flex items. .ion-flex-auto flex: auto Item grows and shrinks based on its content size. .ion-flex-initial flex: initial Item shrinks to its minimum content size but does not grow. .ion-flex-none flex: none Item does not grow or shrink. Flex Grow
The flex-grow CSS property sets the flex grow factor, which specifies how much of the flex container's positive free space, if any, should be assigned to the flex item's main size.
Ionic provides the following utility classes for flex-grow:
.ion-flex-grow-0 flex-grow: 0 Item does not grow beyond its content size. .ion-flex-grow-1 flex-grow: 1 Item grows to fill available space proportionally. Flex Shrink
The flex-shrink CSS property sets the flex shrink factor of a flex item. If the size of all flex items is larger than the flex container, the flex items can shrink to fit according to their flex-shrink value. Each flex line's negative free space is distributed between the line's flex items that have a flex-shrink value greater than 0.
Ionic provides the following utility classes for flex-shrink:
.ion-flex-shrink-0 flex-shrink: 0 Item does not shrink below its content size. .ion-flex-shrink-1 flex-shrink: 1 Item shrinks proportionally when container is too small. Order
The order CSS property sets the order to lay out an item in a flex or grid container. Items in a container are sorted by ascending order value and then by their source code order. Items not given an explicit order value are assigned the default value of 0.
Ionic provides the following utility classes for order:
.ion-order-first order: -1 Item appears first in the flex container. .ion-order-0 order: 0 Item appears in its natural order. .ion-order-1 order: 1 Item appears after items with order 0. .ion-order-2 order: 2 Item appears after items with order 1. .ion-order-3 order: 3 Item appears after items with order 2. .ion-order-4 order: 4 Item appears after items with order 3. .ion-order-5 order: 5 Item appears after items with order 4. .ion-order-6 order: 6 Item appears after items with order 5. .ion-order-7 order: 7 Item appears after items with order 6. .ion-order-8 order: 8 Item appears after items with order 7. .ion-order-9 order: 9 Item appears after items with order 8. .ion-order-10 order: 10 Item appears after items with order 9. .ion-order-11 order: 11 Item appears after items with order 10. .ion-order-12 order: 12 Item appears after items with order 11. .ion-order-last order: 13 Item appears last in the flex container. Responsive Flex Item Classes
All of the flex item classes listed above have additional classes to modify the properties based on the screen size. Instead of the base class name, use {property}-{breakpoint}-{modifier} to only use the class on specific screen sizes, where {breakpoint} is one of the breakpoint names listed in Ionic Breakpoints.
The table below shows the default behavior, where {property} is one of the following: align-self, flex, flex-grow, flex-shrink, or order, and {modifier} is the corresponding value as described above.
.ion-{property}-{modifier} Applies the modifier to the element on all screen sizes. .ion-{property}-sm-{modifier} Applies the modifier to the element when min-width: 576px. .ion-{property}-md-{modifier} Applies the modifier to the element when min-width: 768px. .ion-{property}-lg-{modifier} Applies the modifier to the element when min-width: 992px. .ion-{property}-xl-{modifier} Applies the modifier to the element when min-width: 1200px.
The .ion-no-border utility class can be used to remove borders from Ionic components. This class can be applied to the ion-header and ion-footer components.
<ion-header class="ion-no-border">
<ion-toolbar>
<ion-title>Header - No Border</ion-title>
</ion-toolbar>
</ion-header>
<ion-footer class="ion-no-border">
<ion-toolbar>
<ion-title>Footer - No Border</ion-title>
</ion-toolbar>
</ion-footer>
.ion-no-border The element will have no border.
Ionic uses breakpoints in media queries in order to style an application differently based on the screen size. The following breakpoint names are used in the utility classes listed above, where the class will apply when the width is met.
Breakpoint Name Widthxs 0 sm 576px md 768px lg 992px xl 1200px
