所以我刚开始写代码，所以不要对我评头论足。我试着用vs代码创建我的网站，用html和css创建我的即时通讯，但是我想放在代码左上角的标题和按钮在浏览器上没有显示，我在网上搜索了一下，似乎找不到答案。我正在用google chrome浏览器调试我的代码。
这是html部分：

当我在浏览器上检查有几件事，有超过他们的线，例如我试图改变页面的字体都在一个，并使用这个，但我不认为这是问题...
下面是这一部分（CSS）：

body {
    font-family: 'Trebuchet MS', Arial, Helvetica, sans-serif;
    background-color: white;
    color: #333;
   }

我试着在网站的中上层网页上说：海报商店和潜台词是鼓舞人心的和新的。

标题显示给我在Firefox和Chrome，我有"flex-direction：column;"，以便元素一个在另一个下面。按钮是空的，没有文本。

header {
  background-color: #87CEFA;
  color: white;
  text-align: center;
  padding: 1em;
}
.header-container {
  display: flex;
  align-items: center;
  justify-content: center;
  flex-direction: column;
  height: 100px;
}
header h1 {
  margin: 0;
  font-size: 2em;
}
header .subtext {
  display: block;
  font-size: 1em;
  font-style: italic;
  color: white;
  margin-top: 10px;
}
