有没有一种方法可以让 css 考虑到 svg 占用了多少 space

Question

我有一个 svg 和两个 div，我正在努力使它在您进入网站时让 2 个 div 和 svg 占据整个屏幕，但是使用 svg 会使它变大，因为 css 不考虑 svg 有没有办法让 css 考虑 space svg 占用

我已尝试为 header-container

设置最大高度

我也尝试过调整 2 个 div 的 vh，但是在更小或更大的屏幕上它们会变成不同的大小并且它不起作用

* {
  margin: 0%;
  padding: 0%;
}
body {
  height: 100000px;
}
.header-container {
  width: 100%;
  background-color: #3C8DAD;
  max-height: 100vh;

}

.header-top {
  width: 100%;
  height: 50vh;
}
svg {
  vertical-align: top;
}
.header-bottom {
  width: 100%;
  height: 50vh;
  background-color: #F5A962;
}
.header-content {
  align-items: center;
  width: 45%;
  height: 300px;
  border: 2px red solid;
  position: absolute;
  left: 25%;
  top: 50%; 
}
.name {
  font-family: 'Titillium Web', sans-serif;
  font-size: 40px;
  color: white;
}
.job {
  font-family: 'Noto Serif', serif;
  font-size: 66px;
  font-weight: 800;
  color: white;
  margin-top: 3%;
  margin-left: 4%;
}

<div class="header-container">
  <div class="header-top">
      <div class="header-content">
          <div class="name">Andrew Saenger</div>
          <div class="job">Front-End Web Developer</div>
      </div>
  </div>
  <svg xmlns="http://www.w3.org/2000/svg" viewBox="0 0 1440 320">
    <path fill="#F5A962" fill-opacity="1" d="M0,160L48,160C96,160,192,160,288,138.7C384,117,480,75,576,85.3C672,96,768,160,864,160C960,160,1056,96,1152,80C1248,64,1344,96,1392,112L1440,128L1440,320L1392,320C1344,320,1248,320,1152,320C1056,320,960,320,864,320C768,320,672,320,576,320C480,320,384,320,288,320C192,320,96,320,48,320L0,320Z"></path>
  </svg>
  <div class="header-bottom"></div>
</div>

Answer 1

Flex 可能会在这里工作。尝试将容器设置为 flex。

.header-container {
  display: flex;
}

然后从每个 child 中删除 height 属性并使用 flex: 1.

让它增长

.header-top {
  flex: 1;
}

.header-bottom {
  flex: 1;
}

可以保留 SVG 元素 as-is。它将占据通常 space 的任何空间，其他元素将在容器内调整大小。

如果 max-height 不起作用，您可能需要在 .header-container 上设置 height: 100vh。

Answer 2

我将您的 svg 图片移到 header-top class 中，并对 css.

做了一些修改

* {
  margin: 0%;
  padding: 0%;
}

body {
  height: 100vh; /* changed */
}

.header-container {
  width: 100%;
  display: flex; /* added */
  flex-direction: column; /* added */
  background-color: #3c8dad;
  /* max-height: 100vh; can remove */
}

.header-top {
  width: 100%;
  height: 50vh;
  position: relative; /* added */
}
svg {
  width: 100%; /* added */
  height: max-content; /* added */
  position: absolute; /* added */
  bottom: -30px; /* added */
  /* vertical-align: top; can remove */
}
.header-bottom {
  width: 100%;
  height: 50vh;
  background-color: #f5a962;
}
.header-content {
  /* align-items: center; can remove */
  /* width: 45%; can remove */
  height: max-content; /* changed */
  border: 2px red solid;
  padding: 1rem;
  position: absolute;
  left: 50%; /* changed */
  top: 100%; /* changed */
  transform: translate(-50%, -50%);
  z-index: 5;
}
.name {
  font-family: 'Titillium Web', sans-serif;
  font-size: clamp(1.5em, 5vw, 3em); /* changed */
  color: white;
}
.job {
  font-family: 'Noto Serif', serif;
  font-size: clamp(2em, 5vw, 4em); /* changed */
  font-weight: 800;
  color: white;
}

<div class="header-container">
  <div class="header-top">
    <div class="header-content">
      <div class="name">Andrew Saenger</div>
      <div class="job">Front-End Web Developer</div>
    </div>
    <svg xmlns="http://www.w3.org/2000/svg" viewBox="0 0 1440 320">
          <path
            fill="#F5A962"
            fill-opacity="1"
            d="M0,160L48,160C96,160,192,160,288,138.7C384,117,480,75,576,85.3C672,96,768,160,864,160C960,160,1056,96,1152,80C1248,64,1344,96,1392,112L1440,128L1440,320L1392,320C1344,320,1248,320,1152,320C1056,320,960,320,864,320C768,320,672,320,576,320C480,320,384,320,288,320C192,320,96,320,48,320L0,320Z"
          ></path>
        </svg>
  </div>
  <div class="header-bottom"></div>

Answer 3

您还可以查看网格并在最多 2 个子级的 3x3 网格上构建您的布局（除非您将 SVG 包含到背景中）。

例子

* {
  margin: 0%;
  padding: 0%;
}

.header-container {
  min-height: 100vh;
  display: grid;
  grid-template-rows: 1fr auto 1fr;
  grid-template-columns: repeat(3, 1fr);
  background-image: linear-gradient(to bottom, #3c8dad 50%, #f5a962 50%)
  /* note : you can also use grid-area if that helps set children within the grid via grid-area */
}

svg {
  grid-column: 1 / -1;
  grid-row: 2;
}

.header-content {
  grid-column: 2;
  grid-row: 1 / span 3;
  margin: auto;
}

.name {
  font-family: "Titillium Web", sans-serif;
  font-size: 40px;
  /* calc() or clamp() can be used to set that value */
  color: white;
  line-height: clamp(1ch, 25vh, 150px);
}

.job {
  font-family: "Noto Serif", serif;
  font-size: 66px;
  /* calc() or clamp() can be used to set that value */
  font-weight: 800;
  color: white;
  margin-top: 3%;
  margin-left: 4%;
  min-width: 15ch;
  /* whatever suits you */
  line-height: clamp(1.6ch, 20vh, 100px);
}

.job:first-line {
  /* it avoids the first word to be split */
  word-spacing: 5em;
  /* calc() or clamp() can be used to set that value */
}
