Question

我的浏览器似乎都没有显示css代码的text-shadow属性。我正在阅读udemy教程，但我做到了它告诉我的内容，但似乎不起作用，您能告诉我为什么吗？这是bootstrap 3.4.1，我的常规浏览器是chrome版本80.0，但在firefox，safari，quora，Internet Explorer或Microsoft Edge上不起作用

代码如下：

body {
  background:url("https://images.unsplash.com/photo-1415369629372-26f2fe60c467?ixlib=rb-1.2.1&auto=format&fit=crop&w=634&q=80");
  background-size:cover;
  background-position: center;
  font-family: Lato;
  color: white;
}
html {
  height: 100%
}
#content {
  text-align: center;
  padding-top:25%
  text-shadow: 0 4px 3px rgba(0,0,0,0.4),
               0 8px 13px rgba(0,0,0,0.1),
               0 18px 23px rgba(0,0,0,0.1);
}
h1 {
  font-weight: 700;
  font-size: 5em;
}
hr {
  width: 400px;
  border-top: 1px solid #f8f8f8;
  border-bottom: 2px solid rgba(0, 0, 0, 0.3);
}

您的代码中缺少分号：

#content {
 text-align: center;
 padding-top:25%; **// missing semicolon is the issue in the code.** 
 text-shadow: 0 4px 3px rgba(0,0,0,0.4),
           0 8px 13px rgba(0,0,0,0.1),
           0 18px 23px rgba(0,0,0,0.1);
 }

为什么在浏览器中看不到文字阴影？
