CSS Utilities

Contents

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.

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.

Text Modification

Text Alignment

<ion-grid> <ion-row> <ion-col> <div class="ion-text-start"> <h3>text-start</h3> Lorem ipsum dolor sit amet, consectetur adipiscing elit. Sed ac vehicula lorem. </div> </ion-col> <ion-col> <div class="ion-text-end"> <h3>text-end</h3> Lorem ipsum dolor sit amet, consectetur adipiscing elit. Sed ac vehicula lorem. </div> </ion-col> <ion-col> <div class="ion-text-center"> <h3>text-center</h3> Lorem ipsum dolor sit amet, consectetur adipiscing elit. Sed ac vehicula lorem. </div> </ion-col> </ion-row> <ion-row> <ion-col> <div class="ion-text-justify"> <h3>text-justify</h3> Lorem ipsum dolor sit amet, consectetur adipiscing elit. Sed ac vehicula lorem. </div> </ion-col> <ion-col> <div class="ion-text-wrap"> <h3>text-wrap</h3> Lorem ipsum dolor sit amet, consectetur adipiscing elit. Sed ac vehicula lorem. </div> </ion-col> <ion-col> <div class="ion-text-nowrap"> <h3>text-nowrap</h3> Lorem ipsum dolor sit amet, consectetur adipiscing elit. </div> </ion-col> </ion-row> </ion-grid>
Class Style Rule Description
.ion-text-left text-align: left The inline contents are aligned to the left edge of the line box.
.ion-text-right text-align: right The inline contents are aligned to the right edge of the line box.
.ion-text-start text-align: start The same as text-left if direction is left-to-right and text-right if direction is right-to-left.
.ion-text-end text-align: end The same as text-right if direction is left-to-right and text-left if direction is right-to-left.
.ion-text-center text-align: center The inline contents are centered within the line box.
.ion-text-justify text-align: justify The inline contents are justified. Text should be spaced to line up its left and right edges to the left and right edges of the line box, except for the last line.
.ion-text-wrap white-space: normal Sequences of whitespace are collapsed. Newline characters in the source are handled as other whitespace. Breaks lines as necessary to fill line boxes.
.ion-text-nowrap white-space: nowrap Collapses whitespace as for normal, but suppresses line breaks (text wrapping) within text.

Text Transformation

<ion-grid> <ion-row> <ion-col> <div class="ion-text-uppercase"> <h3>text-uppercase</h3> Lorem ipsum dolor sit amet, consectetur adipiscing elit. Sed ac vehicula lorem. </div> </ion-col> <ion-col> <div class="ion-text-lowercase"> <h3>text-lowercase</h3> Lorem ipsum dolor sit amet, consectetur adipiscing elit. Sed ac vehicula lorem. </div> </ion-col> <ion-col> <div class="ion-text-capitalize"> <h3>text-capitalize</h3> Lorem ipsum dolor sit amet, consectetur adipiscing elit. Sed ac vehicula lorem. </div> </ion-col> </ion-row> </ion-grid>
Class Style Rule Description
.ion-text-uppercase text-transform: uppercase Forces all characters to be converted to uppercase.
.ion-text-lowercase text-transform: lowercase Forces all characters to be converted to lowercase.
.ion-text-capitalize text-transform: capitalize Forces the first letter of each word to be converted to uppercase.

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.

Class Description
.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.

Element Placement

Float Elements

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-grid> <ion-row> <ion-col class="ion-float-left"> <div> <h3>float-left</h3> Lorem ipsum dolor sit amet, consectetur adipiscing elit. Sed ac vehicula lorem. </div> </ion-col> <ion-col class="ion-float-right"> <div> <h3>float-right</h3> Lorem ipsum dolor sit amet, consectetur adipiscing elit. Sed ac vehicula lorem. </div> </ion-col> </ion-row> </ion-grid>
Class Style Rule Description
.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.

Class Description
.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.

Element Display

The display CSS property determines if an element should be visible or not. The element will still be in the DOM, but not rendered, if it is hidden.

<ion-grid> <ion-row> <ion-col class="ion-hide"> <div> <h3>hidden</h3> You can't see me. </div> </ion-col> <ion-col> <div> <h3>not-hidden</h3> You can see me! </div> </ion-col> </ion-row> </ion-grid>
Class Style Rule Description
.ion-hide display: none The element will be hidden.

Responsive Display Attributes

There are also additional classes to modify the visibility based on the screen size. Instead of just .ion-hide for all screen sizes, use .ion-hide-{breakpoint}-{dir} to only use the class on specific screen sizes, where {breakpoint} is one of the breakpoint names listed in Ionic Breakpoints, and {dir} is whether the element should be hidden on all screen sizes above (up) or below (down) the specified breakpoint.

Class Description
.ion-hide-sm-{dir} Applies the modifier to the element when min-width: 576px (up) or max-width: 576px (down).
.ion-hide-md-{dir} Applies the modifier to the element when min-width: 768px (up) or max-width: 768px (down).
.ion-hide-lg-{dir} Applies the modifier to the element when min-width: 992px (up) or max-width: 992px (down).
.ion-hide-xl-{dir} Applies the modifier to the element when min-width: 1200px (up) or max-width: 1200px (down).

Content Space

Element Padding

The padding class sets the padding area of an element. The padding area is the space between the content of the element and its border.

The default amount of padding to be applied is 16px and is set by the --ion-padding variable. See the CSS Variables section for more information on how to change these values.

<ion-grid> <ion-row> <ion-col class="ion-padding"> <div> padding </div> </ion-col> <ion-col class="ion-padding-top"> <div> padding-top </div> </ion-col> <ion-col class="ion-padding-start"> <div> padding-start </div> </ion-col> <ion-col class="ion-padding-end"> <div> padding-end </div> </ion-col> </ion-row> <ion-row> <ion-col class="ion-padding-bottom"> <div> padding-bottom </div> </ion-col> <ion-col class="ion-padding-vertical"> <div> padding-vertical </div> </ion-col> <ion-col class="ion-padding-horizontal"> <div> padding-horizontal </div> </ion-col> <ion-col class="ion-no-padding"> <div> no-padding </div> </ion-col> </ion-row> </ion-grid>
Class Style Rule Description
.ion-padding padding: 16px Applies padding to all sides.
.ion-padding-top padding-top: 16px Applies padding to the top.
.ion-padding-start padding-start: 16px Applies padding to the start.
.ion-padding-end padding-end: 16px Applies padding to the end.

.ion-padding-vertical padding: 16px 0 Applies padding to the top and bottom.
.ion-padding-horizontal padding: 0 16px Applies padding to the left and right.
.ion-no-padding padding: 0 Applies no padding to all sides.

Element Margin

The margin area extends the border area with an empty area used to separate the element from its neighbors.

The default amount of margin to be applied is 16px and is set by the --ion-margin variable. See the CSS Variables section for more information on how to change these values.

<ion-grid> <ion-row> <ion-col class="ion-margin"> <div> margin </div> </ion-col> <ion-col class="ion-margin-top"> <div> margin-top </div> </ion-col> <ion-col class="ion-margin-start"> <div> margin-start </div> </ion-col> <ion-col class="ion-margin-end"> <div> margin-end </div> </ion-col> </ion-row> <ion-row> <ion-col class="ion-margin-bottom"> <div> margin-bottom </div> </ion-col> <ion-col class="ion-margin-vertical"> <div> margin-vertical </div> </ion-col> <ion-col class="ion-margin-horizontal"> <div> margin-horizontal </div> </ion-col> <ion-col class="ion-no-margin"> <div> no-margin </div> </ion-col> </ion-row> </ion-grid>
