Fieldset 类似于带有标题/子标题的 div 容器

Question

我正在尝试在 React 中构建一个字段集，这将允许我在外部边框内添加任何元素（例如按钮等）。 我正在寻找一种方法使边框内的元素透明（其中显示“访问我们”），以便页面的真实背景很好地可见。

使用如下实现，背景被明确设置为黑色。我想避免它，并且没有背景。但是，边界线显示出来了。

有没有巧妙的办法解决这个问题？

谢谢！

function ThankYou(){
  return(
    <div className="thankYouParent">
      <div className="thankYouBox">
        <label className="borderText"> For visiting us </label>
        <label className="thankYouText">Thank You</label>
      </div>
    </div>
  )
}

ReactDOM.render(
  <ThankYou />,
  root
)

.thankYouParent {
  display: flex;
  border: 1px dotted red;
  flex-direction: column;
  align-items: center;
  height: 100vh;
  justify-content: space-between;
  justify-content: center;
}

.thankYouBox {
  display: flex;
  position: relative;
  text-align: center;
  border: 5px solid #ffffff;
  text-transform: uppercase;
  height: 40vh;
  width: 75vw;
  justify-content: center;
}

.thankYouText {
  font-family: interstateBold;
  font-size: 10vw;
  color: white;
  align-self: center;
}

.borderText {
  font-family: interstateRegular;
  position: absolute;
  color: white;
  font-size: 3vh;
  background-color: black;
  padding-left: 1vw;
  padding-right: 1vw;
  bottom: -1.5vh;
  margin-bottom: -3px;
}

body {
  background: black;
}

* {
  box-sizing: border-box;
}

我确实使用了fieldset。当然这个标签基本上用于分组表格，但在你的情况下很有用。

function ThankYou() {
  return (
       <div className="thankYouParent">
      <div className="thankYouBox">
        <div className="wrapper">
          <span className="gap" />
          <div className="borderText">
            <p>For visiting us</p>
          </div>
          <span className="gap" />
          <div className="borderText">
            <p>For visiting us</p>
          </div>
          <span className="gap" />
          <button type="button" id="borderButton">
            <p>Click me</p>
          </button>
          <span className="gap" />
        </div>
        <h2 className="thankYouText">Thank You</h2>
      </div>
    </div>
  );
}

ReactDOM.render(
  <ThankYou />,
  root
)

* {
  margin: 0;
  padding: 0;
  box-sizing: border-box;
  font-family: interstateBold;
  color: white;
  text-transform: uppercase;
}
body {
  background: green;
}

.thankYouParent {
  display: flex;
  border: 1px dotted red;
  flex-direction: column;
  align-items: center;
  height: 100vh;
  justify-content: space-between;
  justify-content: center;
}

.thankYouBox {
  height: 40vh;
  width: 75vw;
  display: flex;
  justify-content: center;
  position: relative;
  border: 5px solid white;
  border-bottom-color: transparent;
}

.thankYouText {
  font-size: 10vw;
  align-self: center;
}

.wrapper {
  display: grid;
  grid-template-columns: auto max-content auto max-content auto max-content auto;
  align-items: flex-end;
  position: absolute;
  left: 0;
  right: 0;
  bottom: 1px;
}

.wrapper::before,
.wrapper::after {
  content: '';
  width: 6px;
  height: 5px;
  position: absolute;
  bottom: -6px;
  background-color: white;
}
.wrapper::before {
  left: -4px;
}
.wrapper::after {
  right: -4px;
}

.gap,
.borderText,
#borderButton {
  display: flex;
  align-items: center;
}
.gap {
  width: 100%;
  height: 5px;
  background-color: white;
  position: relative;
  bottom: -6px;
}

.borderText,
#borderButton {
  height: 50px;
  border: 5px solid transparent;
  background-color: transparent;
  padding-left: 1vw;
  padding-right: 1vw;
  position: relative;
  bottom: -28px;
  font-size: 1.5vh;
}

#borderButton {
  transition: all 0.3s ease-in-out;
  cursor: pointer;
}

#borderButton:hover {
  border: 5px solid white;
}
