html - 如何使这两个带有文本响应的 div？

Question

我有两个这样的 div:

    <div id="splash-container">
     <video id="splash-video" preload autoplay loop muted>
        <source src="videos/splash.mp4" type="video/mp4" />Your browser does not support the video tag. I suggest you upgrade your browser.
     </video>
     <div id="splash-message">MAYUR BHADRACANT</div>
     <div id="splash-submessage">ONLINE PROFILE</div>
   </div>

我希望启动消息显示在启动子消息之上，如下所示: http://prntscr.com/bcxu1r

但是当我调整浏览器大小时:会发生这种情况: http://prntscr.com/bcxuec

我现在的 CSS 是:

    #splash-container {
position: relative;
overflow: hidden;
width: 100vw;
max-width: 100%;
min-height: 100px;
text-align: center;
margin: 0 auto;
}

    #splash-message {
position: absolute;
font-weight: bold;
z-index: 1;
color:white;
font-weight: 300;
letter-spacing: 7px;
left: 0;
width: 100%;
text-align: center;
font-size: 35.5px;
top:40vh;
}


#splash-submessage {
position: absolute;
color: white;
z-index: 1;
font-weight: 300;
letter-spacing: 7px;
left: 0;
width: 100%;
text-align: center;
font-size: 22px;
top:50vh;
}   

感谢任何帮助，谢谢!

使用 Flexbox，您可以将 message 和 submessage 居中，并且可以在 上使用 position: absolute video 将其从元素流中移除，然后使用 transform: translate() 将其居中。

body,
html {
  margin: 0;
  padding: 0;
}
#splash-container {
  display: flex;
  height: 100vh;
  flex-direction: column;
  position: relative;
  align-items: center;
  justify-content: center;
}
video {
  border: 1px solid black;
  top: 50%;
  left: 50%;
  position: absolute;
  transform: translate(-50%, -50%);
}

<div id="splash-container">
  <video id="splash-video" preload autoplay loop muted>
    <source src="videos/splash.mp4" type="video/mp4" />Your browser does not support the video tag. I suggest you upgrade your browser.

  <div id="splash-message">MAYUR BHADRACANT</div>
  <div id="splash-submessage">ONLINE PROFILE</div>
</div>
