JavaScript

Babel includes JSX processing.

Add External Scripts/Pens

HTML

              
                <h3>Preventing event bubbling</h3>
<p>By using the pointer-events css property</p>
<button id="buttonOne">
  <i class="fas fa-times"></i> Icon with events
</button>
<p>Clicking the button will result in a event target of [object HTMLButtonElement] (the button itself)</p>
<p>But clicking the X icon will result in a event target of [object HTMLElement] (the icon element). This is because the event will <a href="https://developer.mozilla.org/en-US/docs/Learn/JavaScript/Building_blocks/Events#event_bubbling_and_capture" target="_blank">bubble up </a>to the button</p>

<button id="buttonTwo">
  <i class="fas fa-check"></i> Icon with pointer-events none
</button>
<p>Because of 'pointer-events: none;' clicking the icon in this button will result in a event target of [object HTMLButtonElement] (the button) just like clicking the button would</p>
