If you want to add reaction buttons to your online content, you can do so easily with this simple guide. These reaction buttons allow viewers or readers to express their feelings or thoughts quickly through emojis like thumbs up, thumbs down, smile, or other fun icons.

First, decide which reactions you want to include. Common options are thumbs up, thumbs down, smile, laugh, hooray, confused, heart, rocket, and eyes. Each of these will have its own button, so pick the ones most relevant to your content or community.

Next, create a button for each reaction. For example, a thumbs-up button might look like this:

This button contains the emoji, and a span to show how many people have used it. When someone clicks the button, the count should increase, and the button can change to show they have reacted.

You’ll want to set up each button similarly, changing the emoji and data attributes as needed. Make sure to include accessibility features like aria-pressed so screen readers understand whether the user has clicked it.

To handle user interaction, use some simple JavaScript. When the button is clicked, toggle the aria-pressed state and update the reaction count. If the person has already clicked it, clicking again should remove their reaction, decreasing the count.

Here’s a basic way to do that:

javascript
document.querySelectorAll(‘.reaction-button’).forEach(button => {
button.addEventListener(‘click’, () => {
const countSpan = button.querySelector(‘.reaction-count’);
let count = parseInt(countSpan.innerText);
const pressed = button.getAttribute(‘aria-pressed’) === ‘true’;

if (pressed) {
  count--;
  button.setAttribute('aria-pressed', 'false');
} else {
  count++;
  button.setAttribute('aria-pressed', 'true');
}
countSpan.innerText = count;

});
});

With this setup, users can click on their favorite reactions, and counts will update instantly on your page. This makes your content more interactive and fun without needing complex coding or third-party tools.

Just copy the button code for each reaction, add the JavaScript to your page, and you’re all set to let your visitors express themselves!
