问题 是否可以将CSS应用于角色的一半?
我在找什么:
一种风格的方式 半 一个角色。 (在这种情况下,一半字母是透明的)
我目前搜索和尝试的内容(没有运气):
- 造型半个字符/字母的方法
- 使用CSS或JavaScript设置角色的一部分
- 将CSS应用于角色的50%
以下是我想要获得的一个例子。

是否存在CSS或JavaScript解决方案,或者我将不得不诉诸图像?我宁愿不去图像路线,因为这个文本最终会动态生成。
更新:
因为很多人都问为什么我想要设计一半角色,这就是原因。我的城市最近花了25万美元为自己定义一个新的“品牌”。这个 商标 是他们想出来的。许多人抱怨简单性和缺乏创造力,并继续这样做。我的目标是想出这个 网站 作为一个笑话。输入'哈利法克斯',你会明白我的意思。 :)

起源
答案:
随意分叉和改进。
- 纯CSS 单个角色
- JavaScript用于跨文本或多个字符的自动化
- 为盲人或视觉屏幕阅读器保留文本可访问性
受损
第1部分:基本解决方案

演示: http://jsfiddle.net/arbel/pd9yB/1694/
这适用于任何动态文本或单个字符,并且都是自动化的。您需要做的就是在目标文本上添加一个类,其余的都要处理。
此外,对于盲人或视障人士的屏幕阅读器,保留了原始文本的可访问性。
单个字符的说明:
纯CSS。您需要做的就是申请 .halfStyle
包含要半个样式的字符的每个元素的类。
对于包含该字符的每个span元素,您可以创建一个数据属性,例如此处 data-content="X"
,以及关于伪元素的使用 content: attr(data-content);
所以 .halfStyle:before
class将是动态的,你不需要为每个实例硬编码。
任何文字的说明:
只需添加 textToHalfStyle
包含文本的元素的类。
// jQuery for automated mode
jQuery(function($) {
var text, chars, $el, i, output;
// Iterate over all class occurences
$('.textToHalfStyle').each(function(idx, el) {
$el = $(el);
text = $el.text();
chars = text.split('');
// Set the screen-reader text
$el.html('<span style="position: absolute !important;clip: rect(1px 1px 1px 1px);clip: rect(1px, 1px, 1px, 1px);">' + text + '</span>');
// Reset output for appending
output = '';
// Iterate over all chars in the text
for (i = 0; i < chars.length; i++) {
// Create a styled element for each character and append to container
output += '<span aria-hidden="true" class="halfStyle" data-content="' + chars[i] + '">' + chars[i] + '</span>';
}
// Write to DOM only once
$el.append(output);
});
});
.halfStyle {
position: relative;
display: inline-block;
font-size: 80px; /* or any font size will work */
color: black; /* or transparent, any color */
overflow: hidden;
white-space: pre; /* to preserve the spaces from collapsing */
}
.halfStyle:before {
display: block;
z-index: 1;
position: absolute;
top: 0;
left: 0;
width: 50%;
content: attr(data-content); /* dynamic content for the pseudo element */
overflow: hidden;
color: #f00;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<p>Single Characters:</p>
<span class="halfStyle" data-content="X">X</span>
<span class="halfStyle" data-content="Y">Y</span>
<span class="halfStyle" data-content="Z">Z</span>
<span class="halfStyle" data-content="A">A</span>
<hr/>
<p>Automated:</p>
<span class="textToHalfStyle">Half-style, please.</span>

第2部分:高级解决方案 - 独立的左右部分

使用此解决方案,您可以单独和独立地设置左右部分的样式。
一切都是一样的,只有更高级的CSS才能实现。
jQuery(function($) {
var text, chars, $el, i, output;
// Iterate over all class occurences
$('.textToHalfStyle').each(function(idx, el) {
$el = $(el);
text = $el.text();
chars = text.split('');
// Set the screen-reader text
$el.html('<span style="position: absolute !important;clip: rect(1px 1px 1px 1px);clip: rect(1px, 1px, 1px, 1px);">' + text + '</span>');
// Reset output for appending
output = '';
// Iterate over all chars in the text
for (i = 0; i < chars.length; i++) {
// Create a styled element for each character and append to container
output += '<span aria-hidden="true" class="halfStyle" data-content="' + chars[i] + '">' + chars[i] + '</span>';
}
// Write to DOM only once
$el.append(output);
});
});
.halfStyle {
position: relative;
display: inline-block;
font-size: 80px; /* or any font size will work */
color: transparent; /* hide the base character */
overflow: hidden;
white-space: pre; /* to preserve the spaces from collapsing */
}
.halfStyle:before { /* creates the left part */
display: block;
z-index: 1;
position: absolute;
top: 0;
width: 50%;
content: attr(data-content); /* dynamic content for the pseudo element */
overflow: hidden;
pointer-events: none; /* so the base char is selectable by mouse */
color: #f00; /* for demo purposes */
text-shadow: 2px -2px 0px #af0; /* for demo purposes */
}
.halfStyle:after { /* creates the right part */
display: block;
direction: rtl; /* very important, will make the width to start from right */
position: absolute;
z-index: 2;
top: 0;
left: 50%;
width: 50%;
content: attr(data-content); /* dynamic content for the pseudo element */
overflow: hidden;

}

第4部分:准备生产
可以在同一页面上的所需元素上使用自定义的不同半风格样式集。
您可以定义多个样式集并告诉插件使用哪个样式集。
该插件使用数据属性 data-halfstyle="[-CustomClassName-]"
在目标上 .textToHalfStyle
元素并自动进行所有必要的更改。
所以,只需在包含文本add的元素上 textToHalfStyle
类和数据属性 data-halfstyle="[-CustomClassName-]"
。该插件将完成剩下的工作。

CSS样式集的类定义也匹配 [-CustomClassName-]
上面提到的部分被链接到 .halfStyle
所以我们会有 .halfStyle.[-CustomClassName-]

我刚刚完成了插件的开发,每个人都可以使用它!希望你会喜欢它。
查看项目 GitHub上 - 查看项目 网站。 (所以你可以看到所有的分割风格)
用法
首先,确保你拥有 jQuery
图书馆包括在内。获取最新jQuery版本的最佳方法是更新头标记:
<script src="http://code.jquery.com/jquery-latest.min.js"></script>
下载文件后,请确保将它们包含在项目中:
<link rel="stylesheet" type="text/css" href="css/splitchar.css">
<script type="text/javascript" src="js/splitchar.js"></script>
标记
你所要做的就是让班级上课 splitchar
,然后是包含文本的元素所需的样式。例如
<h1 class="splitchar horizontal">Splitchar</h1>
完成所有这些后,只需确保在文档就绪文件中调用jQuery函数,如下所示:
$(".splitchar").splitchar();
定制
为了使文本看起来完全符合您的要求,您所要做的就是应用您的设计:
.horizontal { /* Base CSS - e.g font-size */ }
.horizontal:before { /* CSS for the left half */ }
.horizontal:after { /* CSS for the right half */ }
而已!现在你有了 Splitchar
插件全部设置。关于它的更多信息 http://razvanbalosin.com/Splitchar.js/。

编辑(2017年10月): background-clip
更确切地说 background-image options
现在每个主要浏览器都支持: 我可以用吗
是的,你可以只用一个字符,只用CSS。
但是,仅限Webkit(和Chrome):
http://jsbin.com/rexoyice/1/
h1 {
display: inline-block;
margin: 0; /* for demo snippet */
line-height: 1em; /* for demo snippet */
font-family: helvetica, arial, sans-serif;
font-weight: bold;
font-size: 300px;
background: linear-gradient(to right, #7db9e8 50%,#1e5799 50%);
-webkit-background-clip: text;
-webkit-text-fill-color: transparent;
}
<h1>X</h1>
在视觉上,所有使用两个字符的示例(通过JS,CSS伪元素或只是HTML)看起来很好,但请注意,所有这些都会向DOM添加可能导致可访问性的内容 - 以及文本选择/剪切/粘贴问题。

我们只使用CSS伪选择器来做到这一点!
此技术适用于动态生成的内容和不同的字体大小和宽度。
HTML:
<div class='split-color'>Two is better than one.</div>
CSS:
.split-color > span {
white-space: pre-line;
position: relative;
color: #409FBF;
}
.split-color > span:before {
content: attr(data-content);
pointer-events: none; /* Prevents events from targeting pseudo-element */
position: absolute;
overflow: hidden;
color: #264A73;
width: 50%;
z-index: 1;
}
要包装动态生成的字符串,可以使用如下函数:
// Wrap each letter in a span tag and return an HTML string
// that can be used to replace the original text
function wrapString(str) {
var output = [];
str.split('').forEach(function(letter) {
var wrapper = document.createElement('span');
wrapper.dataset.content = wrapper.innerHTML = letter;
output.push(wrapper.outerHTML);
});
return output.join('');
}
// Replace the original text with the split-color text
window.onload = function() {
var el = document.querySelector('.split-color'),
txt = el.innerHTML;
el.innerHTML = wrapString(txt);
}

它可能是无关紧要的,也许不是,但不久前,我创建了一个jQuery函数,它可以执行相同的操作,但是是横向的。
我把它称为“Strippex”对于'stripe'+'text',演示: http://cdpn.io/FcIBg
我不是说这是任何问题的解决方案,但我已经尝试将css应用于一半的角色,但横向,所以这个想法是一样的,实现可能是可怕的,但它的确有效。
啊,最重要的是,我很开心创造它!

这是一个丑陋的画布实现。我尝试了这个解决方案,但结果比我预期的要糟糕,所以无论如何它都在这里。

http://jsfiddle.net/kLXmL/2/
<div>Example Text</div>
$(function(){
$("div").each(function(){
var CHARS = $(this).text().split('');
$(this).html("");
$.each(CHARS,function(index, char){
var canvas = $("<canvas />")
.css("width", "40px")
.css("height", "40px")
.get(0);
$("div").append(canvas);
var ctx = canvas.getContext("2d");
var gradient = ctx.createLinearGradient(0, 0, 130, 0);
gradient.addColorStop("0", "blue");
gradient.addColorStop("0.5", "blue");
gradient.addColorStop("0.51", "red");
gradient.addColorStop("1.0", "red");
ctx.font = '130pt Calibri';
ctx.fillStyle = gradient;
ctx.fillText(char, 10, 130);
});
});
});

如果你对此感兴趣,那么Lucas Bebber的Glitch是一个非常相似和超酷的效果:

使用简单的SASS Mixin创建
.example-one {
font-size: 100px;
@include textGlitch("example-one", 17, white, black, red, blue, 450, 115);
}

我最近可以得到:
$(function(){
$('span').width($('span').width()/2);
$('span:nth-child(2)').css('text-indent', -$('span').width());
});
body{
font-family: arial;
}
span{
display: inline-block;
overflow: hidden;
}
span:nth-child(2){
color: red;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<span>X</span><span>X</span>
演示: http://jsfiddle.net/9wxfY/2/
这是一个只使用一个跨度的版本: http://jsfiddle.net/9wxfY/4/

我刚刚玩@ Arbel的解决方案:
var textToHalfStyle = $('.textToHalfStyle').text();
var textToHalfStyleChars = textToHalfStyle.split('');
$('.textToHalfStyle').html('');
$.each(textToHalfStyleChars, function(i,v){
$('.textToHalfStyle').append('<span class="halfStyle" data-content="' + v + '">' + v + '</span>');
});
body{
background-color: black;
}
.textToHalfStyle{
display:block;
margin: 200px 0 0 0;
text-align:center;
}
.halfStyle {
font-family: 'Libre Baskerville', serif;
position:relative;
display:inline-block;
width:1;
font-size:70px;
color: black;
overflow:hidden;
white-space: pre;
text-shadow: 1px 2px 0 white;
}
.halfStyle:before {
display:block;
z-index:1;
position:absolute;
top:0;
width: 50%;
content: attr(data-content); /* dynamic content for the pseudo element */
overflow:hidden;
color: white;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.0/jquery.min.js"></script>
<span class="textToHalfStyle">Dr. Jekyll and M. Hide</span>

另一个仅限CSS的解决方案(如果您不想编写特定于字母的CSS,则需要数据属性)。这个更全面的工作(测试IE 9/10,Chrome最新和FF最新)
span {
position: relative;
color: rgba(50,50,200,0.5);
}
span:before {
content: attr(data-char);
position: absolute;
width: 50%;
overflow: hidden;
color: rgb(50,50,200);
}
<span data-char="X">X</span>
