CSS3变换旋转文本，左右固定位置，垂直居中 [英] CSS3 transform rotate text, fixed position left and right, vertically centered

问题描述

我正在尝试在浏览器窗口的左侧和右侧放置一个元素，这两个元素都包含一个ul，并且带有CSS变换旋转.我已经设法将.rotate-left及其ul放置在左侧，但是我无法将ul放置在内部的右侧. (如果不支持转换，则必须在从右到左的水平线上可见.)

CSS:

.rotate-left ul li,
.rotate-right ul li {
    display: inline;
}

.rotate-left {
    position: fixed;
    top: 0;
    left: 0;
    bottom: 0;
    width: 10em;
    white-space: nowrap;
    background: silver;
}

.rotate-left ul {
    display: inline-block;
    position: fixed;
    top: 0;
    bottom: 0;
    height: 1.5em;
    margin: auto;
    background: red;
    -webkit-transform-origin: 0 50%;
       -moz-transform-origin: 0 50%;
    -webkit-transform: rotate(-90deg) translate(-50%, 50%);
       -moz-transform: rotate(-90deg) translate(-50%, 50%);
}

.rotate-right {
    position: fixed;
    top: 0;
    right: 0;
    bottom: 0;
    width: 10em; 
    white-space: nowrap;
    background: silver;
}

.rotate-right ul {
    position: fixed;
    top: 0;
    bottom: 0;
    right: 0;
    height: 1.5em; 
    margin: auto;
    background: red;
    -webkit-transform-origin: 0 50%;
       -moz-transform-origin: 0 50%;
    -webkit-transform: rotate(90deg) translate(-50%, 50%);
       -moz-transform: rotate(90deg) translate(-50%, 50%);
}

HTML:

<div class="rotate-left">
    <ul>
        <li>left</li>
        <li>left</li>
        <li>left</li>
    </ul>
</div>
<div class="rotate-right">
    <ul>
        <li>right</li>
        <li>right</li>
        <li>right</li>
    </ul>
</div>

我基于此具有垂直文本的100％高度块.

解决方案

我解决了它，并清理了一下代码.

.left,
.right {
    position: fixed;
    top: 0;
    bottom: 0;
    height: 1.5em;
    margin: auto;
}

.left {
    left: 0;
    -webkit-transform-origin: 0 50%;
       -moz-transform-origin: 0 50%;
        -ms-transform-origin: 0 50%;
         -o-transform-origin: 0 50%;
            transform-origin: 0 50%;
    -webkit-transform: rotate(-90deg) translate(-50%, 50%);
       -moz-transform: rotate(-90deg) translate(-50%, 50%);
        -ms-transform: rotate(-90deg) translate(-50%, 50%);
         -o-transform: rotate(-90deg) translate(-50%, 50%);
            transform: rotate(-90deg) translate(-50%, 50%);
}

.right {
    right: 0;
    -webkit-transform-origin: 100% 50%;
       -moz-transform-origin: 100% 50%;
        -ms-transform-origin: 100% 50%;
         -o-transform-origin: 100% 50%;
            transform-origin: 100% 50%;
    -webkit-transform: rotate(90deg) translate(50%, 50%);
       -moz-transform: rotate(90deg) translate(50%, 50%);
        -ms-transform: rotate(90deg) translate(50%, 50%);
         -o-transform: rotate(90deg) translate(50%, 50%);
            transform: rotate(90deg) translate(50%, 50%);
}

I'm trying to position one element to the left and one to the right of the browser window, both contains an ul with CSS transform rotate. I have managed to position .rotate-left and its ul to the left, but I have been unable to position the ul inside .rotate-right to the right. (It needs to be visible on a horizontal line from right to left if transform is not supported.)

CSS:

.rotate-left ul li,
.rotate-right ul li {
    display: inline;
}

.rotate-left {
    position: fixed;
    top: 0;
    left: 0;
    bottom: 0;
    width: 10em;
    white-space: nowrap;
    background: silver;
}

.rotate-left ul {
    display: inline-block;
    position: fixed;
    top: 0;
    bottom: 0;
    height: 1.5em;
    margin: auto;
    background: red;
    -webkit-transform-origin: 0 50%;
       -moz-transform-origin: 0 50%;
    -webkit-transform: rotate(-90deg) translate(-50%, 50%);
       -moz-transform: rotate(-90deg) translate(-50%, 50%);
}

.rotate-right {
    position: fixed;
    top: 0;
    right: 0;
    bottom: 0;
    width: 10em; 
    white-space: nowrap;
    background: silver;
}

.rotate-right ul {
    position: fixed;
    top: 0;
    bottom: 0;
    right: 0;
    height: 1.5em; 
    margin: auto;
    background: red;
    -webkit-transform-origin: 0 50%;
       -moz-transform-origin: 0 50%;
    -webkit-transform: rotate(90deg) translate(-50%, 50%);
       -moz-transform: rotate(90deg) translate(-50%, 50%);
}

HTML:

<div class="rotate-left">
    <ul>
        <li>left</li>
        <li>left</li>
        <li>left</li>
    </ul>
</div>
<div class="rotate-right">
    <ul>
        <li>right</li>
        <li>right</li>
        <li>right</li>
    </ul>
</div>

I have built upon this 100% height block with vertical text.

解决方案

I solved it and cleaned the code up a bit.

.left,
.right {
    position: fixed;
    top: 0;
    bottom: 0;
    height: 1.5em;
    margin: auto;
}

.left {
    left: 0;
    -webkit-transform-origin: 0 50%;
       -moz-transform-origin: 0 50%;
        -ms-transform-origin: 0 50%;
         -o-transform-origin: 0 50%;
            transform-origin: 0 50%;
    -webkit-transform: rotate(-90deg) translate(-50%, 50%);
       -moz-transform: rotate(-90deg) translate(-50%, 50%);
        -ms-transform: rotate(-90deg) translate(-50%, 50%);
         -o-transform: rotate(-90deg) translate(-50%, 50%);
            transform: rotate(-90deg) translate(-50%, 50%);
}

.right {
    right: 0;
    -webkit-transform-origin: 100% 50%;
       -moz-transform-origin: 100% 50%;
        -ms-transform-origin: 100% 50%;
         -o-transform-origin: 100% 50%;
            transform-origin: 100% 50%;
    -webkit-transform: rotate(90deg) translate(50%, 50%);
       -moz-transform: rotate(90deg) translate(50%, 50%);
        -ms-transform: rotate(90deg) translate(50%, 50%);
         -o-transform: rotate(90deg) translate(50%, 50%);
            transform: rotate(90deg) translate(50%, 50%);
}
