我试过这个，但它显示了数字。
/* Wrap alphabet. */

使用 content: "("counter(item, lower-alpha)")"; 而不是 content: "(" counter(item) ") "; 应该可以

counter(item)只给你整数而不是数字。所以，你需要使用 JavaScript 或 jQuery 来循环并设置一个属性，比如data-count并设置字母表。
然后，您需要将counter(item)替换为attr(data-count)，以便它显示字母。
使用此 CSS：
/* Wrap alphabet. */
ol.wrapAlphabet {
list-style-type: lower-alpha;
counter-reset: item;
margin-left: 0;
padding-left: 0;
margin-top: 5px;
padding-left: 40px;
}
ol.wrapAlphabet li {
}
ol.wrapAlphabet li:before {
display: inline-block;
content: "(";
counter-increment: item;
width: 2em;
margin-left: -1.75em;
}
ol.wrapAlphabet li:after {
display: inline-block;
content: ")";
counter-increment: item;
width: 2em;
margin-left: -3.5em;
}

如果您使用的是更好的现代浏览器（我假设），您可以简单地替换：
content: "("counter(item)";
跟：
content: "("counter(item, lower-alpha)")";
