Solving the problem of equal-width spaces in CSS browsers_Experience exchange

css Browser

但是   也不是很可靠,比如空格间距非常大,那么我们必须增加多个占位符,同时页面的体积会变得非常大。

同时,注意到 Safari 中的   宽度是已设定字符的空格宽度(Safari 的默认字体为 Times),也就是说一个中文字符需要两个占位符。

具体情况如下图所示:

其实,这不是 Safari 的问题,而是字体的问题。解决的方式就是使用下面的属性

font-family: '宋体';将 Safari 的默认字体设置成“宋体”等中英文等宽的字体,就能解决。Windows 版本的 Safari 字体设置,需要直接使用中文“宋体”这样的名称而不是“Simsun”(了解原因的兄弟请告诉我)。

但至此,我们的根本目标没有解决,就是能否避免使用   这样的占位符,而使用“原生”的空格。考虑针对空白的相应 CSS 属性,具体了解有关 white-space 的用法,接下来就比较好处理了。

总结下使用 white-space 实现等宽空格的条件,有两个。需要设置对应的属性

white-space: pre;

然后设置等宽字符(包括等宽空格)即可。综合起来,就是这样

font-family: '宋体', Simsun;
white-space: pre;

由于使用了中文 CSS 名称,所以在实际使用中需要考虑样式的字符编码问题。同时,需要额外考虑的是,苹果机是否有“宋体”(或者其他等宽的字体),有苹果机的兄弟请帮忙测试下。

--Split--

感谢 小马 提供的另外一个思路,就是使用 em 单位。1em 简单的说,就可以认为是一个字符宽度;同理,.5em 就是半个字符。那么,上面的情况就可以使用这样写。

区:

对应的 CSS 应为

.half-word {width: .5em;}
.two-word{width:2em;}

经测试通过。

--Split--

In view of the above two different methods, I personally think that they should be considered according to the actual situation. For example, the first method, although it relies on specific fixed-width fonts, does not add other additional structures, which will be more convenient for future maintenance; the second method takes more into account the actual application situation (and does not use relies on a specific monospaced font), but also adds additional structure.

So, taking into account future maintainability and analyzing from a "semantic" perspective, the first approach is recommended. In actual application situations, when the application needs to be more complicated, individuals will choose the second one.
