随意分叉和改进。
- 单个字符的纯 CSS
- JavaScript 用于跨文本或多个字符的自动化
- 为盲人或视障人士的屏幕阅读器保留文本可访问性
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,剩下的就都搞定了。
此外,为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。
单字解释:
纯 CSS。您需要做的就是将.halfStyle
class 应用于包含您想要半样式的字符的每个元素。
对于包含字符的每个 span 元素,您可以创建一个数据属性,例如 here data-content="X"
,并在伪元素上使用,content: attr(data-content);
因此.halfStyle:before
该类将是动态的,您无需为每个实例对其进行硬编码。
对任何文本的解释:
只需将textToHalfStyle
类添加到包含文本的元素。
// 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;
}

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。
一切都一样,只有更高级的 CSS 才能发挥作用。
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 {

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 Half-Style 样式集。您可以定义多个样式集并告诉插件使用哪一个。
该插件使用data-halfstyle="[-CustomClassName-]"
目标.textToHalfStyle
元素上的数据属性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
class 和 data 属性data-halfstyle="[-CustomClassName-]"
。该插件将完成其余的工作。
此外,CSS 样式集的类定义与[-CustomClassName-]
上面提到的部分匹配并链接到.halfStyle
,因此我们将有.halfStyle.[-CustomClassName-]
