给博客做的几个美化
[title]canvans粒子背景特效[/title]
将下面的代码另存为js，然后在<body></body>中引用，下附压缩版可自行下载
如果是wordpress的话可以在footer.php中引用
<?php if (!wp_is_mobile()): ?>
<script src="<?php bloginfo('template_directory'); ?>/js/love.min.js"></script>
<script src="<?php bloginfo('template_directory'); ?>/js/canvas-nest.min.js"></script>
<script src="<?php bloginfo('template_directory'); ?>/js/activate-power-mode.js "></script>
<script>
POWERMODE.colorful = true; // 冒光特效
POWERMODE.shake = false; // 抖动特效
document.body.addEventListener('input', POWERMODE); // 为所有 input 标签都加上特效
</script>
<?php endif; ?>这里我加了个判断在手机端不显示效果。
下面是源码，自行调整

[title]文本框打字烟花特效[/title]
觉得单纯的打字还是有点单调了，于是给它加一个，同样在手机端我选择放弃，同时关闭了振动的效果（感觉是真的不爽）
源码就不贴了，直接给压缩文件吧

[title]鼠标点击的爱心效果[/title]
懒，自己下吧

以上所有效果本博客上都用到了，自己查看
