一：基本解決方案：
html:

代碼如下:

X
Y
Z
A

css:

代碼如下:

.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;
}

效果如圖：

這種方法用于任何動(dòng)態(tài)文本或單個(gè)字符，并且都是自動(dòng)適用的。所有你需要做的就是在目標(biāo)文本上添加一個(gè)class，剩下的就解決了。

同時(shí)，保留了原文的可訪(fǎng)問(wèn)性，可以被盲人或視障人士使用的屏幕閱讀器識(shí)別。

單個(gè)字符的實(shí)現(xiàn)：

純CSS。所有你需要做的就是把.halfStyle class用在每個(gè)你想要渲染一半樣式字符的元素上。

對(duì)于每個(gè)包含字符的span元素，你可以添加一個(gè)data屬性，比如data-content=”X”，并且在偽元素上使用content:attr(data-content)；這樣，.halfStyle:before class將會(huì)是動(dòng)態(tài)的，你不需要為每個(gè)實(shí)例進(jìn)行硬編碼

以下其它效果自行測(cè)試了。。。

二：左右開(kāi)弓，兩邊都設(shè)置樣式
更改CSS:

代碼如下:

.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：設(shè)置水平一半的樣式
CSS:

代碼如下:

.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：水平三分之一的樣式
css:

代碼如下:

.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：垂直三分之的樣式
css:

代碼如下:

.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 */
}
