Adding Fireworks ???? Effect to WordPress Comment Interface

While browsing other blogs these past few days, I noticed several sites had firework ???? effects when typing in the comment section, and some even had vibration effects. So I searched for it and found the implementation method is very simple. I'll share how to achieve it below.WordPressImplementation method for comment box firework and vibration effects. Firework effect js file download:The main component for achieving the firework blooming effect is this js file. The specific code is as follows.

Specific implementation steps for the firework comment effect:Upload the downloaded js file to your website. You can upload it to your theme folder or any other folder you prefer. Then, edit your theme's footer.php file and add the following line of code.

<?php if (is_single() || is_page() ) { ?>
<script src="<?php bloginfo('template_directory'); ?>/js/activate-power-mode.js "></script> 
<script>
POWERMODE.colorful = true; // ture 为启用礼花特效
POWERMODE.shake = false; // false 为禁用震动特效
document.body.addEventListener('input', POWERMODE);
</script>
<?php }?>

If you're unsure where to add it, place it before the <\/body> tag. Note: If you didn't upload the js file to your theme folder, you need to modify the path after `script src=`.
