问题描述

我希望头像图片能对齐到屏幕右侧，但无法实现。我尝试过使用text-align属性，但没有效果。

解决方案

方法1：利用Flex布局调整容器对齐

因为.home是Flex容器，.image作为Flex子元素，可通过给.image添加Flex布局并设置justify-content: flex-end，让内部图片靠右：

.home .image {
  flex: 1 1 40rem;
  z-index: 1;
  display: flex;
  justify-content: flex-end; /* 让容器内元素靠右对齐 */
}
.home .image img {
  width: 80%;
  display: block;
  /* 移除无效的float:right */
}

方法2：给图片设置自动左外边距

无需修改容器布局，直接给图片添加margin-left: auto，利用自动外边距将图片推到右侧：

.home .image img {
  width: 80%;
  display: block;
  margin-left: auto;
}

为什么`text-align`和`float:right`无效？

text-align仅控制行内元素/文本在块级容器中的对齐，你的图片设置了display:block，属于块级元素，因此text-align不生效。
.home是Flex容器，Flex子元素中的float属性会被忽略，所以float:right无法发挥作用。
