CSS中怎么设置半个字符的样式

CSS中怎么设置半个字符的样式，针对这个问题，这篇文章详细介绍了相对应的分析和解答，希望可以帮助更多想解决这个问题的小伙伴找到更简单易行的方法。

一：基本解决方案：
html:

代码如下:

<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>

css:

代码如下:

.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;
}

效果如图：

这种方法用于任何动态文本或单个字符，并且都是自动适用的。所有你需要做的就是在目标文本上添加一个class，剩下的就解决了。

同时，保留了原文的可访问性，可以被盲人或视障人士使用的屏幕阅读器识别。

单个字符的实现：

纯CSS。所有你需要做的就是把.halfStyle class用在每个你想要渲染一半样式字符的元素上。

对于每个包含字符的span元素，你可以添加一个data属性，比如data-content=”X”，并且在伪元素上使用content:attr(data-content)；这样，.halfStyle:before class将会是动态的，你不需要为每个实例进行硬编码

以下其它效果自行测试了。。。

二：左右开弓，两边都设置样式
更改CSS:

代码如下:

.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;
pointer-events: none; /* so the base char is selectable by mouse */
color: #000; /* for demo purposes */
text-shadow: 2px 2px 0px #0af; /* for demo purposes */
}

三：设置水平一半的样式
CSS:

代码如下:

.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 top part */
display:block;
z-index:2;
position:absolute;
top:0;
height: 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 bottom part */
display:block;
position:absolute;
z-index:1;
top:0;
height: 100%;
content: attr(data-content); /* dynamic content for the pseudo element */
overflow:hidden;
pointer-events: none; /* so the base char is selectable by mouse */
color: #000; /* for demo purposes */
text-shadow: 2px 2px 0px #0af; /* for demo purposes */
}

四：水平三分之一的样式
css:

代码如下:

.halfStyle { /* base char and also the bottom 1/3 */
position:relative;
display:inline-block;
font-size:80px; /* or any font size will work */
color: transparent;
overflow:hidden;
white-space: pre; /* to preserve the spaces from collapsing */
color: #f0f;
text-shadow: 2px 2px 0px #0af; /* for demo purposes */
}
.halfStyle:before { /* creates the top 1/3 */
display:block;
z-index:2;
position:absolute;
top:0;
height: 33.33%;
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 #fa0; /* for demo purposes */
}
.halfStyle:after { /* creates the middle 1/3 */
display:block;
position:absolute;
z-index:1;
top:0;
height: 66.66%;
content: attr(data-content); /* dynamic content for the pseudo element */
overflow:hidden;
pointer-events: none; /* so the base char is selectable by mouse */
color: #000; /* for demo purposes */
text-shadow: 2px 2px 0px #af0; /* for demo purposes */
}

五：垂直三分之的样式
css:

代码如下:

.halfStyle { /* base char and also the right 1/3 */
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 */
color: #f0f; /* for demo purposes */
text-shadow: 2px 2px 0px #0af; /* for demo purposes */
}
.halfStyle:before { /* creates the left 1/3 */
display:block;
z-index:2;
position:absolute;
top:0;
width: 33.33%;
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 middle 1/3 */
display:block;
z-index:1;
position:absolute;
top:0;
width: 66.66%;
content: attr(data-content); /* dynamic content for the pseudo element */
overflow:hidden;
pointer-events: none; /* so the base char is selectable by mouse */
color: #000; /* for demo purposes */
text-shadow: 2px 2px 0px #af0; /* for demo purposes */
}
