如果是这样，那么他就强烈要求。
If so then he is putting that to strongly.

< bris一个元素几乎没有用，它经常被滥用到
插入空白行或伪段落当应该使用真正的段落标记
时，或者应该使用CSS边距时的间距，或者获得
元素以在元素之前和之后具有换行符
应设置为display：block;相反。
但是使用< br>有一些合法用途，一个例子是
在< addresselement中创建一个换行符：
< address>
我的名字< br>
我的地址
<地址>

<bris an element with few appropriate uses, it''s often abused to
insert blank lines or "pseudo paragraphs" when real paragraph markup
should be used, or spacing when CSS margins should be used, or to get an
element to have a line break before and after for which the element
should be set to "display:block" instead.
But there are a few legitimate uses for using <br>, one example would be
to create a line break inside an <addresselement:
<address>
My name<br>
My address
<address>

元素在前后换行时将元素
设置为"显示：块"相反。

你的意思是他没有在书中解释这一点吗？
我想Eric指的是使用中的常见滥用连续< brtags到
创建垂直间距。这是笨拙，粗糙和不可靠的，所以肯定它应该用CSS代替
。
此外，甚至合法使用< brcan经常被其他标记取代，
通常< div>，这可能有助于造型。
消除所有< brtags听起来像是一种误解但是。不管是埃里克的错误构想还是你的错误，这都是不可能的。

Do you mean he does not explain that in the book?
I guess Eric refers to the common abuse of using successive <brtags to
create vertical spacing. That''s clumsy, coarse and unreliable, so surely it
should be replaced by the use of CSS.
Besides, even legitimate uses of <brcan often be replaced by other markup,
usually <div>, and this may help in styling.
Eliminating all <brtags sounds like a misconception, though. It''s
impossible to say whether it would be Eric''s misconception or yours.
