调整大小并正确放置视差图像

如何解决调整大小并正确放置视差图像

涵盖这方面的大多数历史线索不是我特别需要的，或者它们的屏幕截图/链接的文件不再可以通过Internet访问，从而很难遵循。

我希望我的视差图像能覆盖页面的左上角，从上到下。这是我坐着的侧面照。我认为将高度/宽度分别扩展到100％和50％应该可以解决问题，但是我不确定如何实现。到目前为止，灰色部分位于水平居中位置，我希望它位于页面的右侧部分。

我还试图将导航栏放在屏幕右侧的顶部，并且也固定在标题位置。

background-position: left;并不总是将图像向左（从中心）移动。我认为这是因为我没有在百分位数中使用高度/宽度，而是在像素高度中使用了

CSS：

@charset "UTF-8";

/* Nav Bar */

ul {
  list-style-type: none;
  margin: 0;
  padding: 0;
  overflow: hidden;
  background-color: #333;
}

li {
  float: left;
}

li a {
  display: block;
  color: white;
  text-align: center;
  padding: 14px 16px;
  text-decoration: none;
}


/* Change the link color to #111 (black) on hover */
li a:hover {
  background-color: #111;
}

.active {
  background-color: #4CAF50;
}

/* Centered text */
.centered {
  position: absolute;
  top: 50%;
  left: 50%;
  transform: translate(-50%,-50%);
}

一如既往地感谢您抽出宝贵的时间。

解决方法

下面是您想要的，但是问题是，当屏幕缩小时，链接将换行到下一行，但是会以其他方式起作用

* {
  padding: 0;
  margin: 0;
  box-sizing: border-box;
}

.container {
  width: 70%;
  height: 100%;
}

.parallax {
  z-index: 9999;
  /* Image to be used */
  background: url('x.png') no-repeat;
  height: 100%;
  width: 100%;
  /*scrolling effect*/
  background-attachment: fixed;
  background-position: left;
  background-size: auto;
}
