Touch Target
Touch targets are the parts of the screen that respond to user input. They extend beyond the visual bounds of an element.
For example, a button may appear to be 48 x 36 px, but the padding surrounding it comprises the full 48 x 48 px touch target.
Material Design spec states that touch targets should be at least 48 x 48 px.
The MDC Web library provides mixins and guidance on adding an increased touch target for the following components:
- Button
- Chips
- Checkbox
- Radio
- Mini FAB
Design & API Documentation
Installation
npm install @material/touch-target
Basic Usage
HTML Structure
For a given button component:
<button class="mdc-button">
<div class="mdc-button__ripple"></div>
<span class="mdc-button__label">My Inaccessible Button</span>
</button>
You would add an increased touch target as follows:
<div class="mdc-touch-target-wrapper">
<button class="mdc-button mdc-button--touch">
<div class="mdc-button__ripple"></div>
<div class="mdc-button__touch"></div>
<span class="mdc-button__label">My Accessible Button</span>
</button>
</div>
Note that the outer mdc-touch-target-wrapper
element is only necessary if you want to avoid potentially overlapping touch targets on adjacent elements (due to collapsing margins).
Styles
@use "@material/touch-target/mdc-touch-target";
