每次我们读完一行，我们的眼睛就不得不停下来，跳到下一行的开头. 如果我们在正常和水平镜像之间切换书写方向，我们就可以在每一行的末尾继续阅读.请参见示例here (imgur). 这就是所谓的boustrophedon (wiki).
我想显示文本段落的网站与交替阅读方向这样. 如何实现这一点并不重要，只要我们不需要手动复制.
我知道我可以使用css来镜像整个段落，或者只将此镜像应用于每隔一个子 node :
p {
transform: scaleX(-1);
}
// or
:nth-child(even) {
transform: scaleX(-1);
}
而且我知道可以使用target odd or even lines to change their display color的Java脚本. 遗憾的是，仅在Tim M.(https://jsfiddle.net/Fptq2/2/，第21行之后)给出的示例中添加‘spans[i].style="scaleX(-1)"；’并没有显示出任何效果.
编辑:如何在html文档中镜像文本段落的第二行？
下面的代码片段允许您动态地定位文本块内的每隔一行.以下是实现这一目标的合乎逻辑的步骤:
<span>个标签中.<span>个标签.<span>个标记.<p>标记，并在其中添加每行的<span>标记.<p>个标签加回<div>.我把scaleX和scaleY都取反了，以获得所需的文本结果.
确保内容使用率达到text-align: center也是关键.
document.addEventListener("DOMContentLoaded", function() {
wrapWordsInSpan("boustrophedon");
wrapLinesInP("boustrophedon");
});
function wrapWordsInSpan(divId) {
var div = document.getElementById(divId);
var words = div.innerText.split(/\s+/);
div.innerHTML = "";
words.forEach(function(word) {
var span = document.createElement("span");
span.textContent = word + " ";
div.appendChild(span);
});
}
function wrapLinesInP(divId) {
var div = document.getElementById(divId);
var spans = div.getElementsByTagName("span");
var lines = {};
for (var i = 0; i < spans.length; i++) {
var span = spans[i];
var offsetTop = span.offsetTop;
if (!lines[offsetTop]) {
lines[offsetTop] = [];
}
lines[offsetTop].push(span);
}
for (var line in lines) {
var p = document.createElement("p");
lines[line].forEach(function(span) {
p.appendChild(span);
});
div.appendChild(p);
}
}#boustrophedon p {
text-align: center;
}
#boustrophedon p:nth-child(even) {
transform: scaleY(-1);
transform: scaleX(-1);
