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

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";
