Always shows an empty banner

[lxy071130]

As I use the plugin I got the empty banner like this and I don't know why.My addictional code is:

<link
          rel="stylesheet"
          href="//cdn.jsdelivr.net/npm/docsify-top-banner-plugin@latest/dist/style.css"
  />   
<script>
window.$docsify = {
topBanner: {
      content: 'hello world',
      Zindex: -1
    }
}
</script>
<script src="https://cdn.jsdelivr.net/npm/docsify-top-banner-plugin@latest/dist/index.js"></script>  

Is this conflict with some other plugins I use or I just didn't use it correctly?

I noticed that it seems that the text is not centered
