又一次博客优化记录

不知道干什么我就折腾博客，首页的欢迎页面一直是用的图片，正好看到一个还不错的视频，于是拿来当动态欢迎图，效果还不错，写在主题设置里的，谁让typecho切换主题会清空设置呢，因老王非专业选手，过几天就忘了，故而代码放这里备忘下😣。
找了蛮多视频结果选择困难症犯了😄……，顺带在别处扣了个背景上飘浮的星星特效。
01｜背景图改为视频

{collapse}
{collapse-item label="div 部分"}

<video id="cat_index_topvideo" autoplay="" loop="" muted="" style="min-height: 100%;height: 100%;width: 100%;object-fit: cover;border-radius: .5rem;"> <source src="https://wangge.me/usr/themes/web/style/bg/welcome_1.mp4" type="video/mp4"> </video>

02｜背景添加星星效果

{collapse-item label="style.css 添加"}

#star-sky-banner {display: block;position: fixed;margin: 0;padding: 0;border: 0;outline: 0;left: 0;top: 0;width: 100%;height: 100%;pointer-events: none;z-index: 1;}

{/collapse-item}
{collapse-item label="footer.php添加"}

<canvas id="star-sky-banner" style="width: 100%;height: 100%;"></canvas>
<script src="<?php $this->options->themeUrl('style/dark.js'); ?>" type="text/javascript"></script>
