html - css float 不在右侧显示 div

Question

我在使用 css float:right; 时遇到问题当我删除 .container 中的 float:right; 时，.app-chat-image-more 将显示，但我需要 float :右；

这是 DEMO 您看不到图像。当你删除 float:right in .container 然后你可以看到图像。使用 float:right; 如何处理图片的显示？ .有人可以帮我吗？

.container {
  max-width: 60%;
  -webkit-border-radius: 10px;
  -webkit-border-top-right-radius: 3px;
  -webkit-border-bottom-right-radius: 3px;
  -moz-border-radius: 10px;
  -moz-border-radius-topright: 3px;
  -moz-border-radius-bottomright: 3px;
  border-radius: 10px;
  border-top-right-radius: 10px;
  border-bottom-right-radius: 10px;
  border-top-right-radius: 3px;
  border-bottom-right-radius: 3px;
  background-color: #dcf8c6;
  box-shadow: 0 1px 0.5px rgba(0, 0, 0, 0.13);
  float: right;
}

.app-chat-image-more {
  width: 100%;
  -webkit-border-radius: 10px;
  -webkit-border-top-right-radius: 3px;
  -webkit-border-bottom-right-radius: 3px;
  -moz-border-radius: 10px;
  -moz-border-radius-topright: 3px;
  -moz-border-radius-bottomright: 3px;
  border-radius: 10px;
  border-top-right-radius: 3px;
  border-bottom-right-radius: 3px;
  overflow: hidden;
  display: inline-block;
  float: right;
}

.chat-image-more-item {
  position: relative;
  float: left;
  width: calc(100% / 2 - 2px);
  width: -webkit-calc(100% / 2 - 2px);
  width: -moz-calc(100% / 2 - 2px);
  padding: 1px;
}

.app-chat-image-item {
  position: relative;
  padding-top: 100%;
  position: relative;
  overflow: hidden;
  -webkit-background-size: cover;
  -moz-background-size: cover;
  -o-background-size: cover;
  background-size: cover;
  background-position: center;
}

.chat-hidden-image-item {
  position: absolute;
  display: block;
  left: 0;
  right: 0;
  top: 0;
  bottom: 0;
  width: 100%;
  height: 100%;
  opacity: 0;

给.container一个width: 100%。

因为您设置了 max-width: 60%，所以宽度实际上是 60%。但是，您需要设置宽度才能使用 float: right。

.container {
  width: 100%;
  max-width: 60%;
  -webkit-border-radius: 10px;
  -webkit-border-top-right-radius: 3px;
  -webkit-border-bottom-right-radius: 3px;
  -moz-border-radius: 10px;
  -moz-border-radius-topright: 3px;
  -moz-border-radius-bottomright: 3px;
  border-radius: 10px;
  border-top-right-radius: 10px;
  border-bottom-right-radius: 10px;
  border-top-right-radius: 3px;
  border-bottom-right-radius: 3px;
  background-color: #dcf8c6;
  box-shadow: 0 1px 0.5px rgba(0, 0, 0, 0.13);
  float: right;
}

.app-chat-image-more {
  width: 100%;
  -webkit-border-radius: 10px;
  -webkit-border-top-right-radius: 3px;
  -webkit-border-bottom-right-radius: 3px;
  -moz-border-radius: 10px;
  -moz-border-radius-topright: 3px;
  -moz-border-radius-bottomright: 3px;
  border-radius: 10px;
  border-top-right-radius: 3px;
  border-bottom-right-radius: 3px;
  overflow: hidden;
  display: inline-block;
  float: right;
}

.chat-image-more-item {
  position: relative;
  float: left;
  width: calc(100%/2 - 2px);
  width: -webkit-calc(100%/2 -2px);
  width: -moz-calc(100%/2 -2px);
  padding: 1px;
}

.app-chat-image-item {
  position: relative;
  padding-top: 100%;
  position: relative;
  overflow: hidden;
  -webkit-background-size: cover;
  -moz-background-size: cover;
  -o-background-size: cover;
  background-size: cover;
  background-position: center;
}

.chat-hidden-image-item {
  position: absolute;
  display: block;
  left: 0;
  right: 0;
  top: 0;
  bottom: 0;
  width: 100%;
  height: 100%;
  opacity: 0;
}
