关于字体大小 [英] About font sizes
问题描述
据我所知，大多数浏览器制造商已经同意16px的
默认字体大小。
因此，这应该是一个准确的转换百分比：
px％
16 = 100
14 = 87.5
13 = 81.25
12 = 75
10 = 62.5
我认为最好坚持一个百分比将产生一个数字 -
而不是使用90％这样的东西获得14.4。浏览器只会向上计算
或者它可以显示的字体大小，对吗？
至于em，我说的是1em = 16px ？
这意味着1.2em是19.2px（浏览器四舍五入到19px - 如果默认
大小是16）？
As I understand it, most browser manufacturers have agreed on 16px for their
default font size.
So, this should be an accurate conversion for percentages:
px %
16 = 100
14 = 87.5
13 = 81.25
12 = 75
10 = 62.5
I assume it''s better to stick to a percentage that will yield a round number -
rather than using something like 90% to get 14.4. A browser will just round up
or down to a font size it can display, correct?
As for em, am I correct in saying 1em = 16px?
Does that mean 1.2em is 19.2px (rounded by the browser to 19px - if the default
size is 16)?

我认为对于大多数
用户来说，16px很容易阅读，因此微软将其设置为默认值，其他浏览器供应商
跟随套件。
虽然它可以被用户覆盖。
所以，这应该是百分比的准确转换：
不，因为你不知道用户没有表达自己的
偏好。

I think it is more of a case that 16px is easy to read for a majority of
users, so Microsoft set it as their default, and other browser vendors
followed suite.
Its overridable by the user though.
So, this should be an accurate conversion for percentages:
No, since you don''t know that the user hasn''t expressed their own
preference.
As for em, am I correct in saying 1em = 16px?
不，见上文。

假设16是默认值，这就是用户目前正在使用的内容，并且它没有被覆盖
....
然后我的数学是正确的。
一个基本指南（基于16）可能看起来像这样（假设上面的陈述！）
137.5％= 22px（h1）
125％= 20px（h2）
112.5％= 18px（h3）
100％= 16px（大）
87.5％= 14px（中）
81.25％= 13px（小）
75％= 12px（较小）
62.5％= 10px（ legalese）
重点是，如果你打算使用百分比，你可以调整到客户端浏览器可以显示的字体大小。如果16是默认值，那么最好用它作为调整的基础。
assuming 16 is the default, and this is what the user is currently using, and it
has not been overridden....
then my math is correct.
A basic guide (based on 16) might look like this (assuming the above statement!)
137.5% = 22px (h1)
125% = 20px (h2)
112.5% = 18px (h3)
100% = 16px (large)
87.5% = 14px (medium)
81.25% = 13px (small)
75% = 12px (smaller)
62.5% = 10px (legalese)
The point is, if you are going to use percentages, you might as well adjust to a
font size that the client browser can display. If 16 is the default, then it''s
best to use that as a basis for adjustment.

这是很多假设。

That is a lot of assumptions.

系统可以将字体大小调整到可以接受的范围，因此担心它的任何一点都不会真的花费b / b $

Systems can round font sizes to something acceptable, so there''s not really
any point in worrying about it.
