使用css强制抗锯齿：这是一个神话吗？ [英] Forcing anti-aliasing using css: Is this a myth?

问题描述

最近，一个客户抱怨在IE6系统字体的外观。基本上第三个问题是IE6不支持字体平滑/反锯齿（我知道你可以在操作系统设置或某事开启它）。但是有人抛出了这个gem：

你可以通过使用pt而不是px在css中强制使用字体反别名。

我在各种浏览器中做了一个快速的POC，看到没有什么区别。我在网上找到了一个引用，最后发布在此论坛上：

这听起来像是一个web开发人员城市神话，我的感觉是它的BS。有没有人遇到过？

解决方案

不，没有真正的方法来控制这个web开发人员。

小的例外是，你可以通过使用Flash通过 sIFR ，有些浏览器不会对位图/像素字体进行反锯齿（因为它们不应该更多信息：抗锯齿 / 抗抗锯齿）。

此外，像Daniel所说的，对于所有字体使用 em ，请参阅 The Incredible Em&有关此的详细信息，请参见CSS弹性布局。

Recently a client has complained about the appearance of a system font in IE6. Basically th issue is that IE6 doesn't support font-smoothing/anti-aliasing (I know you can turn it on in an OS setting or something). But someone threw out this gem:

"You can force font anti-alias in css by using pt instead of px."

I did a quick POC in various browsers and saw no difference. I found one reference to it online, last post on this forum:

http://www.webmasterworld.com/css/3280638.htm

This sounds like the equivalent of a web developer urban myth, my feeling is it's BS. Has anyone ever encountered it?

解决方案

No, there's not really any way to control this as a web developer.

Small exceptions are that you can do some fake forcing of anti-aliasing by using Flash through sIFR, and some browsers won't anti-alias bitmap/pixel fonts (as they shouldn't, more info: Anti-Aliasing / Anti-Anti-Aliasing).

Also, as Daniel mentioned, it's ideal to be using em units for all fonts, see The Incredible Em & Elastic Layouts with CSS for more information about this.
