图片没有出现在图片库中

Question

我正在尝试基于 Javascript30 (Repo Link) 的 Flex Panel Gallery 创建一个游泳图片库。当试图在浏览器中显示网站时，图像立即超出框架，我只能看到页面上五个弹性列的背景。

我不确定为什么它们在浏览器中被向下推到视线之外，以及为什么直到我在列中单击后才显示文本（不是按列方向）。

const panels = document.querySelectorAll('.panel');

function toggleOpen() {
  console.log('Hello');
  this.classList.toggle('open');
}

function toggleActive(e) {
  console.log(e.propertyName);
  if (e.propertyName.includes('flex')) {
    this.classList.toggle('open-active');
  }
}

panels.forEach(panel => panel.addEventListener('click', toggleOpen));
panels.forEach(panel => panel.addEventListener('transitionend', toggleActive));

body {
  box-sizing: border-box;
  background: lightblue;
  font-family: "Source Sans Pro", sans-serif;
  font-size: 20px;
  font-weight: 200;
  margin: 0;
  box-sizing: inherit;
}

.image-panels {
  min-height: 100vh;
  overflow: hidden;
  display: flex;
}

.panel {
  display: flex;
  background: #6B0F9C;
  box-shadow: inset 0 0 0 5px rgba(255, 255, 255, 0.1);

    flex 0.7s cubic-bezier(0.61, -0.19, 0.7, -0.11),
    background 0.2s;
  font-size: 20px;
  background-size: cover;

Answer 1

通过观看 repo 站点示例，您应该将图像背景应用于父 div，如下所示：

<div class="panel" id="first-panel">
  <p>Join</p>
  <p>This</p>
  <p>Quarter!</p>
</div>

const panels = document.querySelectorAll('.panel');

function toggleOpen() {
  console.log('Hello');
  this.classList.toggle('open');
}

function toggleActive(e) {
  console.log(e.propertyName);
  if (e.propertyName.includes('flex')) {
    this.classList.toggle('open-active');
  }
}

panels.forEach(panel => panel.addEventListener('click', toggleOpen));
panels.forEach(panel => panel.addEventListener('transitionend', toggleActive));

body {
  box-sizing: border-box;
  background: lightblue;
  font-family: "Source Sans Pro", sans-serif;
  font-size: 20px;
  font-weight: 200;
  margin: 0;
  box-sizing: inherit;
}

.image-panels {
  min-height: 100vh;
  overflow: hidden;
  display: flex;
}

.panel {
  display: flex;
  background: #6B0F9C;
  box-shadow: inset 0 0 0 5px rgba(255, 255, 255, 0.1);
  color: white;
  text-align: center;
  align-items: center;
  transition:
    font-size 0.7s cubic-bezier(0.51, -0.19, 0.7, -0.11),
    flex 0.7s cubic-bezier(0.61, -0.19, 0.7, -0.11),
    background 0.2s;
  font-size: 20px;
  background-size: cover;
  background-position: center;
  flex: 1;
  justify-content: center;
  flex-direction: column;
}

#first-panel {
  background-image: url(https://picsum.photos/id/10/2500/1667);
}

#second-panel {
  background-image: url(https://picsum.photos/id/10/2500/1667);
}

#third-panel {
  background-image: url(https://picsum.photos/id/10/2500/1667);
}

#fourth-panel {
  background-image: url(https://picsum.photos/id/10/2500/1667);
}

#fifth-panel {
  background-image: url(https://picsum.photos/id/10/2500/1667);
}

.panel > * {
  display: flex;
  margin: 0;
  width: 100%;
  transition: transform 0.5s;
  flex: 1 0 auto;
  justify-content: center;
  align-items: center;
}

.panel > *:first-child {
  transform: translateY(-100%);
}

.panel.open-active > *:first-child {
  transform: translateY(0);
}

.panel > *:last-child {
  transform: translateY(100%);
}

.panel.open-active > *:last-child {
  transform: translateY(0);
}

.panel div p {
  text-shadow: 0 0 4px rgba(0, 0, 0, 0.72), 0 0 14px rgba(0, 0, 0, 0.45);
  font-size: 2em;
}

.panel div p:nth-child(2) {
  font-size: 4em;
}

.panel.open {
  flex: 5;
  font-size: 40px;
}
