CSS: 有没有等价于vh + vw的单位?

CSS: Is there a Unit that the Equivalent to vh + vw?

我想知道是否有 measures 1% of the width and height of a page 的字体大小单位?我认为这会让我更容易,并帮助我做我想做的事情,而不必使用 JavaScript (尽管任何答案都是可以接受的,只要它有效)。如果没有这样的单位,我该如何操作字体来做到这一点?我唯一能想到的是 % 但是,我不知道它们是否有效。

我的问题来了,当我尝试以两种方式调整页面大小时。它适用于预期目的,但是当您将页面调整得非常小时,它看起来不会很好。我是一个完美主义者,当它不起作用时我会很烦恼。这是我的代码(准确地说是我的代码片段。如果你想要完整的代码,我会把它编辑到这里):

更新(0.1): 我正在尝试使用 javascript 做出更好的答案。我还没有完成代码。这是:

function myFunction() {
  var h11a = document.getElementById("h1_1_a");
  var w = window.innerWidth;
  var h = window.innerHeight;
  window.addEventListener("resize", function() {
    var w2 = window.innerWidth;
    var h2 = window.innerHeight;
    if (w > w2) {
      h11a.style.fontSize = "calc(6*(0vh + 1.5vw))";
    } else if (h > h2) {
      h11a.style.fontSize = "calc(6*(3vh + 0vw))";
    }
  });
}
* {
  box-sizing: border-box;
}
body {
  margin: 0%;
}
.div_1 {
  position: relative;
  width: 100%;
  Height: 20%;
  background-color: #000000;
  border-top: .4vh solid #ff7400;
  border-left: .4vh solid #ff7400;
  border-right: .4vh solid #ff7400;
  border-bottom: .2vh solid #ff7400;
}
#div_1_a {
  height: 100%;
  display: flex;
  align-items: center;
  justify-content: center;
}
#h1_1_a {
  line-height: 100%;
  height: 60%;
  color: #ff7400;
  font-size:calc(6*(1vh + 1vw));
  white-space: nowrap
}

非常感谢任何帮助!

使用 calc( n * ( 1vh + 1vw ) ),其中 n 是您选择的系数。

不,没有这样的单位,但也许 vmin 可以解决您的问题。

编辑:

如果你想垂直和水平居中,你可以使用这样的东西:

.wrapper {
  height: 100vh;
  width: 100vw;
  display: flex;
  justify-content: center;
  align-items: center;
}
.wrapper__text {
  font-size: 30vmin;
}
<div class="wrapper">
  <div class="wrapper__text">My text</div>
</div>

I want the font size to be in accordance to the div it's held in (in this case )

我的理解是您希望文本与容器保持相同的比例。我将使用 SVG 来避免这个问题:

* 
  { 
  box-sizing: border-box;
}
body
{
  margin:0%;
}
.div_1
{
  position:relative;
  width:100%;
  Height:20%;
  background-color:#000000;
  border-top:.4vh solid #ff7400;
  border-left:.4vh solid #ff7400;
  border-right:.4vh solid #ff7400;
  border-bottom:.2vh solid #ff7400;
}
<html lang="en">
  <head> 
    <link rel="stylesheet" href="halloweenEvent1.css" type="text/css"/>
    <meta charset="UTF-8"/>
    <meta name="description" content="A Halloween Event Website"/>
    <meta name="keywords" content="Brad,Website,Personal,Information,Halloween"/>
    <meta name="author" content="Bradley William Elko"/>
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>Halloween Event (Home)</title>
  </head>
  <body>
    <div class="div_1">
        <svg class="svg" viewbox="0 0 100 20">
            <text fill="#ff7400" x="50" y="10" font-size="50%" text-anchor="middle" dominant-baseline="central">Halloween Website</text>
        </svg>
    </div>
  </body>
</html>

缺点是失去了h1的语义。
