我在寻找什么:
设置角色的一个 HALF 的方式。 (在这种情况下,一半字母是透明的)
我目前搜索并尝试过的内容(没有运气):
下面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
因为很多人都问过为什么我想要设置一半角色,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”。 logo 就是他们想出来的。许多人抱怨简单性和缺乏创造力,并继续这样做。我的目标是将这个 website 作为一个笑话。输入'哈利法克斯',你会看到我的意思。

随意分叉和改进。

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,为盲人或视障人士的屏幕阅读器保留原始文本的可访问性。
单个字符的说明:
纯CSS。您需要做的就是将.halfStyle
类应用于包含您想要半个样式的字符的每个元素。
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data-content="X"
,并在伪元素上使用content: attr(data-content);
,这样.halfStyle:before
类将是动态的,你不需要为每个实例硬编码。
任何文字说明:
只需将textToHalfStyle
类添加到包含文本的元素中。

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。
该插件在目标data-halfstyle="[-CustomClassName-]"
元素上使用数据属性.textToHalfStyle
,并自动进行所有必要的更改。
因此,只需在包含文本的元素上添加textToHalfStyle
类和数据属性data-halfstyle="[-CustomClassName-]"
。该插件将完成剩下的工作。
CSS样式集的类定义也与上面提到的[-CustomClassName-]
部分匹配,并且链接到.halfStyle
,因此我们将.halfStyle.[-CustomClassName-]

答案 1 :(得分:468)
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。
首先,确保包含jQuery
库。获取最新jQuery版本的最佳方法是使用以下命令更新头标记:
<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>
您所要做的就是将类splitchar
取消,然后将所需的样式添加到包装文本的元素中。 e.g
<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();
为了使文本看起来完全符合您的要求,您只需要按照以下方式应用您的设计:
.horizontal { /* Base CSS - e.g font-size */ }
.horizontal:before { /* CSS for the left half */ }
.horizontal:after { /* CSS for the right half */ }
而已!现在你已经设置了Splitchar
插件。有关它的更多信息,请访问http://razvanbalosin.com/Splitchar.js/。
答案 2 :(得分:213)
编辑(2017年10月):现在,每个主要浏览器都支持
background-clip
或更确切background-image options
:CanIUse
是的,您只能使用一个字符而且只能使用CSS。
仅限Webkit(和Chrome):
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;
}
&#13;
<h1>X</h1>
&#13;
从视觉上看,所有使用两个字符的示例(无论是通过JS,CSS伪元素还是只是HTML)看起来都很好,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。
答案 3 :(得分:151)
我们只使用CSS伪选择器来做!
此技术适用于动态生成的内容以及不同的字体大小和宽度。
<强> HTML:强>
<div class='split-color'>Two is better than one.</div>

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);
}

答案 18 :(得分:3)
仅用于历史记录!
我为自己5到6年前的工作提出了一个解决方案,即Gradext(纯JavaScript和纯CSS,无依赖项)。
技术上的解释是您可以创建这样的元素:
<span>A</span>
现在,如果要在文本上进行渐变,则需要创建一些多层,每个层分别进行特殊着色,并且创建的光谱将说明渐变效果。
例如,看看这是<span>
内的 lorem 一词,它将引起水平渐变效果(check the examples):
<span data-i="0" style="color: rgb(153, 51, 34);">L</span>
<span data-i="1" style="color: rgb(154, 52, 35);">o</span>
<span data-i="2" style="color: rgb(155, 53, 36);">r</span>
<span data-i="3" style="color: rgb(156, 55, 38);">e</span>
<span data-i="4" style="color: rgb(157, 56, 39);">m</span>
您也可以在很长一段很长的时间内继续执行此模式。
如果要在文本上创建垂直渐变效果怎么办?
然后有另一个解决方案可能会有所帮助。我将详细描述。
再次假设我们的第一个<span>
。但是内容不应该单独是字母;内容应该是全文,现在我们要一次又一次地复制相同的 <span>
(跨度数将定义渐变的质量,更大的跨度,更好的结果,但性能较差)。看看这个:
<span data-i="6" style="color: rgb(81, 165, 39); overflow: hidden; height: 11.2px;">Lorem ipsum dolor sit amet, tincidunt ut laoreet dolore magna aliquam erat volutpat.</span>
<span data-i="7" style="color: rgb(89, 174, 48); overflow: hidden; height: 12.8px;">Lorem ipsum dolor sit amet, tincidunt ut laoreet dolore magna aliquam erat volutpat.</span>
<span data-i="8" style="color: rgb(97, 183, 58); overflow: hidden; height: 14.4px;">Lorem ipsum dolor sit amet, tincidunt ut laoreet dolore magna aliquam erat volutpat.</span>
<span data-i="9" style="color: rgb(105, 192, 68); overflow: hidden; height: 16px;">Lorem ipsum dolor sit amet, tincidunt ut laoreet dolore magna aliquam erat volutpat.</span>
<span data-i="10" style="color: rgb(113, 201, 78); overflow: hidden; height: 17.6px;">Lorem ipsum dolor sit amet, tincidunt ut laoreet dolore magna aliquam erat volutpat.</span>
<span data-i="11" style="color: rgb(121, 210, 88); overflow: hidden; height: 19.2px;">Lorem ipsum dolor sit amet, tincidunt ut laoreet dolore magna aliquam erat volutpat.</span>
如果要使这些渐变效果移动并从中创建动画怎么办?
嗯,还有另一种解决方案。您绝对应该检查animation: true
甚至.hoverable()
方法,这将导致基于光标位置的渐变开始! (听起来很酷xD)
这就是我们在文本上创建渐变(线性或径向)的方式。如果您喜欢这个主意或想进一步了解它,则应检查提供的链接。
也许这不是最好的选择,也许不是执行此操作的最佳方法,但是它将为创造令人兴奋和令人愉悦的动画打开一些空间,以激励其他人寻求更好的解决方案。
它将允许您在文本上使用渐变样式,甚至IE8也支持!

<div data-content="A CSS only solution..."></div>
<div data-content="Try it on Firefox!"></div>
这个想法是为每个字符应用一个水平 CSS 掩码,隐藏它的前半部分 [0 - 0.5em] 并显示后半部分 [0.5em - 1em]。
掩码的宽度为 mask-size: 1em
以匹配字符串中第一个字符的宽度。
通过使用 mask-repeat: repeat-x
,相同的掩码应用于第二个、第三个字符等。
我认为使用字体monospace
可以解决使用等宽字母的问题,但我错了。
相反,我使用 text-transform: full-width
解决了这个问题,不幸的是,我相信只有 Firefox 支持。
使用相对单位 em
允许设计根据 font-size
放大/缩小。
如果无法选择 Firefox,则使用此脚本进行救援。
它的工作原理是为每个字符插入一个子 span
。在每个 span 内,一个非重复的 CSS 掩码放置在 [0% - 50%] 和 [50% - 100%] 字母宽度(即 span 元素的宽度)之间。
这样我们就不再有使用等宽字符的限制了。

dataElement = document.getElementById("data"),
content = dataElement.textContent,
zoom = function (fontSize) {
dataElement.style['font-size'] = fontSize + 'em';

for(var i = 0; i < content.length; ++i) {
