旋转的文本产生不一致的结果

Question

我正在尝试显示旋转文本，它始终绝对定位在其父项的底部。父项是浏览器 window 的 100% 高度，对于所有 browser/screen 大小，我希望文本从底部显示 50px。

这是我的代码：

html,body,.carousel,.carousel a.item { height: 100%; }
.carousel a.item {
  height: 100%;
  padding-top: 100px;
  position: relative;
  overflow: hidden;
  width: 25%;
  float: left;
}
.rotate {
  zoom: 1;
  white-space: nowrap;
  position: absolute;
  bottom: 0;
  right: 0;
  z-index: 3;
  display: block;
  width: 100%;
  background: pink;
  -webkit-transform-origin: right bottom;
  -moz-transform-origin: right bottom;
  -o-transform-origin: right bottom;
  -ms-transform-origin: right bottom;
  transform-origin: right bottom;
  -webkit-transform: rotate(-90deg);
  -moz-transform: rotate(-90deg);
  -o-transform: rotate(-90deg);
  -ms-transform: rotate(-90deg);
  transform: rotate(-90deg);
}
.carousel a.item h1 {
  color: #fff;
  position: absolute;
  right: 0;
  bottom: 0;
  height: 100%;
  width: 100%;
  background: blue;
  z-index: 5;
  display: block;
}
.bg-image {
  background-repeat: no-repeat;
  background-position: center center;
  -webkit-background-size: cover;
  -moz-background-size: cover;
  -o-background-size: cover;
  background-size: cover;
}

<div class="carousel">
  <a href="#" class="item bg-image" style="background-image: url('https://placeholdit.imgix.net/~text?txtsize=33&txt=300%C3%97800&w=300&h=800');">
    <div class="rotate">
      <h1>Some really long title thats quite long. Did I say it was long?</h1>
    </div>
  </a>
  <a href="#" class="item bg-image" style="background-image: url('http://www.freelargeimages.com/wp-content/uploads/2014/12/Landscape_01.jpg');">
    <div class="rotate">
      <h1>This is really short</h1>
    </div>
  </a>
  <a href="#" class="item bg-image" style="background-image: url('https://placeholdit.imgix.net/~text?txtsize=33&txt=300%C3%97800&w=300&h=800');">
    <div class="rotate">
      <h1>Short but also longer but not to long</h1>
    </div>
  </a>
  <a href="#" class="item bg-image" style="background-image: url('http://www.freelargeimages.com/wp-content/uploads/2014/12/Landscape_01.jpg');">
    <div class="rotate">
      <h1>Some really long title thats quite long. Did I say it was long?</h1>
    </div>
  </a>

</div>

到目前为止，我的代码有 fiddle 设置：https://jsfiddle.net/77xzfsfa/ 这是我要实现的目标的图片：

Answer 1

当你放置旋转时：-90px

真正的底部是左边

真正的权利是底部

那么我们可以说：

 bottom -> right
 right -> top
 top -> left
 left -> bottom

但是当你把这里

 left: 0px;

它不是真的0px;

因为在水平位置从div的中心计算

你的代码是正确的

像这样

.carousel a.item h1 {
    color: #fff;
    font-size: 15px;
    font-weight: 400;
    position: absolute; bottom:10px; left: 150px;
    height: 100%;
    width: 100%;
    background: blue;
    z-index: 5;
    display: block;
}

Answer 2

您需要像这样调整 transform-origin 和 .rotate 元素的位置：

html,body,.carousel,.carousel a.item { height: 100%; }
.carousel a.item {
  height: 100%;
  padding-top: 100px;
  position: relative;
  overflow: hidden;
  width: 25%;
  float: left;
}
.rotate {
  white-space: nowrap;
  position: absolute;
  bottom: 50px;
  left: 100%;
  transform-origin: left bottom;
  transform: rotate(-90deg);
}
.carousel a.item h1 {
  color: #fff;
}
.bg-image {
  background-repeat: no-repeat;
  background-position: center center;
  background-size: cover;
}

<div class="carousel">
  <a href="#" class="item bg-image" style="background-image: url('https://placeholdit.imgix.net/~text?txtsize=33&txt=300%C3%97800&w=300&h=800');">
    <div class="rotate"><h1>Some really long title thats quite long. Did I say it was long?</h1></div>
  </a>
  <a href="#" class="item bg-image" style="background-image: url('http://www.freelargeimages.com/wp-content/uploads/2014/12/Landscape_01.jpg');">
    <div class="rotate"><h1>This is really short</h1></div>
  </a>
  <a href="#" class="item bg-image" style="background-image: url('https://placeholdit.imgix.net/~text?txtsize=33&txt=300%C3%97800&w=300&h=800');">
    <div class="rotate"><h1>Short but also longer but not to long</h1></div>
  </a>
  <a href="#" class="item bg-image" style="background-image: url('http://www.freelargeimages.com/wp-content/uploads/2014/12/Landscape_01.jpg');">
    <div class="rotate"><h1>Some really long title thats quite long. Did I say it was long?</h1></div>
  </a>

</div>

请注意，为了简洁起见，我删除了代码段中的所有供应商前缀，并删除了不必要的 CSS.

Answer 3

试试这个，只需将 <br> 放在代码中：

<div class="rotate"> <h1>Short but also longer but not to long</h1> <br> </div>

Answer 4

您不需要绝对定位旋转元素的内容。

只需调整变换和变换原点即可。

.rotate{
    zoom: 1;
  white-space: nowrap;
  position: absolute;
  z-index: 3;
  display: inline-block;
  position: absolute;
  right: 0;
  bottom: 50px;
  transform:translate(100%,0%) rotate(-90deg);
  transform-origin:bottom left;
}


.carousel a.item h1 {
    color: #fff;
    z-index: 5;
}

* {
  margin: 0;
}
html,
body,
.carousel,
.carousel a.item {
  height: 100%;
}
.carousel a.item {
  height: 100%;
  padding-top: 100px;
  position: relative;
  overflow: hidden;
  width: 25%;
  float: left;
}
.rotate {
  zoom: 1;
  white-space: nowrap;
  position: absolute;
  z-index: 3;
  display: inline-block;
  position: absolute;
  right: 0;
  bottom: 50px;
  transform: translate(100%, 0%) rotate(-90deg);
  transform-origin: bottom left;
}
.carousel a.item h1 {
  color: #fff;
  z-index: 5;
}
.bg-image {
  background-repeat: no-repeat;
  background-position: center center;
  -webkit-background-size: cover;
  -moz-background-size: cover;
  -o-background-size: cover;
  background-size: cover;
}

<div class="carousel">
  <a href="#" class="item bg-image" style="background-image: url('https://placeholdit.imgix.net/~text?txtsize=33&txt=300%C3%97800&w=300&h=800');">
    <div class="rotate">
      <h1>Some really long title thats quite long. Did I say it was long?</h1>
    </div>
  </a>
  <a href="#" class="item bg-image" style="background-image: url('http://www.freelargeimages.com/wp-content/uploads/2014/12/Landscape_01.jpg');">
    <div class="rotate">
      <h1>This is really short</h1>
    </div>
  </a>
  <a href="#" class="item bg-image" style="background-image: url('https://placeholdit.imgix.net/~text?txtsize=33&txt=300%C3%97800&w=300&h=800');">
    <div class="rotate">
      <h1>Short but also longer but not to long</h1>
    </div>
  </a>
  <a href="#" class="item bg-image" style="background-image: url('http://www.freelargeimages.com/wp-content/uploads/2014/12/Landscape_01.jpg');">
    <div class="rotate">
      <h1>Some really long title thats quite long. Did I say it was long?</h1>
    </div>
  </a>

</div>
