CSS非ASCII字符最佳实践,cssascii最佳实践


问题场景

在写样式时经常需要用到非ASCII字符的属性值,如下:

?
1 2 3 4 5 6 7 8 9 10 11 .hot_list .sign_discount:before {    content: "满减";    padding: 0 8px;    margin-right: 7px;    font-size: 12px;    line-height: 14px;    color: #fff;    text-align: center;        border-radius: 11px; }

但是Chrome下展示时有些时候会显示乱码:

\

除content外,font字体也是经常需要用于非ASCII字符的值,如font-family: “微软雅黑”

最佳实践

为避免以上这类编码问题,CSS推荐在涉及非ASCII字符时统一使用反斜杠转义以避免编码问题:

backslash escapes allow authors to refer to characters they cannot easily put in a document. In this case, the backslash is followed by at most six hexadecimal digits (0..9A..F), which stand for the ISO 10646 ([ISO10646]) character with that number, which must not be zero. (It is undefined in CSS 2.1 what happens if a style sheet does contain a character with Unicode codepoint zero.) If a character in the range [0-9a-fA-F] follows the hexadecimal number, the end of the number needs to be made clear.

所以上例可以改成:

?
1 2 3 4 5 6 7 8 9 10 11 .hot_list .sign_discount:before {    content: "\6ee1\51cf";    padding: 0 8px;    margin-right: 7px;    font-size: 12px;    line-height: 14px;    color: #fff;    text-align: center;        border-radius: 11px; }
