html - 表内的加载器 <td>

Question

我正在尝试将加载程序放入表中，但它不起作用。问题是当我将 div 放入 td 时，表格格式不起作用。

当我检查元素时，div 在表格之外。

.loader {
  background: #000;
  background: radial-gradient(#222, #000);
  bottom: 0;
  left: 0;
  overflow: hidden;
  position: fixed;
  right: 0;
  top: 0;
  z-index: 99999;
}
.loader-inner {
  height: 60px;
  left: 0;
  position: absolute;
  right: 0;
  width: 100px;
}
.loader-line-wrap {
  animation: spin 2000ms cubic-bezier(.175, .885, .32, 1.275) infinite;
  box-sizing: border-box;
  height: 50px;
  left: 0;
  overflow: hidden;
  position: absolute;
  top: 0;
  transform-origin: 50% 100%;
  width: 100px;
}
.loader-line {
  border: 4px solid transparent;
  border-radius: 100%;
  box-sizing: border-box;
  height: 100px;
  left: 0;
  margin: 0 auto;
  position: absolute;
  right: 0;
  top: 0;
  width: 100px;
}
.loader-line-wrap:nth-child(1) {
  animation-delay: -50ms;
}
.loader-line-wrap:nth-child(2) {

  width: 34px;
  top: 35px;
}
@keyframes spin {
  0%, 15% {
    transform: rotate(0);
  }
  100% {
    transform: rotate(360deg);
  }
}

Answer 1

如果您需要在 <td> 中包含加载图形那么你不应该使用固定定位。

这是一种解决方案。移除固定定位和相关属性。将定位设置为相对以及 .loader 的高度和宽度.

.loader {
  position: relative;
  background: #000;
  background: radial-gradient(#222, #000);
  overflow: hidden;
  z-index: 99999;
  width: 100px;
  height: 100px;
}
.loader-inner {}
.loader-line-wrap {
  animation: spin 2000ms cubic-bezier(.175, .885, .32, 1.275) infinite;
  box-sizing: border-box;
  height: 50px;
  left: 0;
  overflow: hidden;
  position: absolute;
  top: 0;
  transform-origin: 50% 100%;
  width: 100px;
}
.loader-line {
  border: 4px solid transparent;
  border-radius: 100%;
  box-sizing: border-box;
  height: 100px;
  left: 0;
  margin: 0 auto;
  position: absolute;
  right: 0;
  top: 0;
  width: 100px;
}
.loader-line-wrap:nth-child(1) {
  animation-delay: -50ms;
}
.loader-line-wrap:nth-child(2) {
  animation-delay: -100ms;
}
.loader-line-wrap:nth-child(3) {
  animation-delay: -150ms;
}
.loader-line-wrap:nth-child(4) {
  animation-delay: -200ms;
}
.loader-line-wrap:nth-child(5) {
  animation-delay: -250ms;
}
.loader-line-wrap:nth-child(1) .loader-line {
  border-color: hsl(0, 80%, 60%);
  height: 90px;
  width: 90px;
  top: 7px;
}
.loader-line-wrap:nth-child(2) .loader-line {
  border-color: hsl(60, 80%, 60%);
  height: 76px;
  width: 76px;
  top: 14px;
}
.loader-line-wrap:nth-child(3) .loader-line {
  border-color: hsl(120, 80%, 60%);
  height: 62px;
  width: 62px;

}
@keyframes spin {
  0%, 15% {
    transform: rotate(0);

  100% {

}
table td {
  border: 1px solid #CCC;
