何时使用
换行 vs CSS 定位？
我经常想知道如何正确使用
W3schoools.org 表示对空行使用
但我仍然对其他人可能有的任何进一步的澄清或意见感兴趣。我经常发现自己选择不使用
并不是说它非常重要，而是这个例子让我思考这个问题，其中一个流行的（“权威”）网站使用了一个我不确定是否完全语义的 ：
<p>Lorem ipsum dolor sit amet, consectetur tempor laborum.</p>
<br>
<a href="#readmore">more >></a>
I've often wondered about the proper use of a <br> line break. Seems that often they are incorrectly used for positioning or clearing content where CSS should instead be used.
W3schoools.org says to use <br> for blank lines, but not for creating or separating paragraphs. Looking over W3C HTML5 spec draft, it's a little clearer that the <br> would be used when content requires a line break such as lines of an address or blank lines in poetry, where intended by the author.
But I'm still interested in any further clarification or input anyone else may have. I often find myself opting not to use <br> tags but instead just styling elements with the desired clears, margins, paddings, etc. to create the space desired.
Not that it's supremely important, but here's the example that got me thinking about this where a popular ("authoritative") site used a <br> that I'm not sure is quite semantic. Here I would've just cleared the <a> from it's siblings via CSS:
<p>Lorem ipsum dolor sit amet, consectetur tempor laborum.</p>
<br>
<a href="#readmore">more >></a>

对我来说，换行符只能在段落内使用来指示新行。在过去，在段落之间添加换行符已经被使用，当时 HTML 看起来像 Chop Suey，HTML 文档的语义看起来就像学前班的人使用 Dreamweaver。
我个人依靠边距和填充来分隔内容，如果我必须使用
To me, linebreaks should only be used inside paragraphs to indicate a new line. Adding line-breaks between paragraphs was used back in the day, when HTML looked like Chop Suey and the semantics of the HTML document looked like someone from preschool used Dreamweaver.
I personally rely on margins and padding for content separation, if I have to use a
<br />it means I've done something wrong. I think lines of an address are a perfect example of proper usage and I would stick to only those scenarios.当换行符在无样式文档中具有语义含义时。
正如有人所说，诗歌就是一个很好的例子——按照惯例，诗歌是在行与行之间换行的。地址也是如此。用段落元素标记一行诗或一个地址是没有意义的，因为它们与整个地址或诗的一节更好匹配。
When the linebreak has semantic meaning within the unstyled document.
As someone said, poetry is a good example - conventionally, poetry is written with a linebreak between lines. As are addresses. It does not make sense to mark up a line of a poem or an address with a paragraph element, as these are better matches to the whole address or a stanza of the poem.
我同意该规范， br 应该用于在段落中创建新的文本行。从语义上讲，它是有意义的——段落是带有一些顶部或底部边距的文本块，而 br 指定没有边距，只是一个换行符和相同的行高/行距。
I agree with the specification, br should be used to create new lines of text within a paragraph. Semantically it makes, sense- a paragraph is a block of text with some top or bottom margin, whereas br specifies no margin, just a newline a the same line-height / line-spacing.
当客户可以编辑内容时，我会使用换行符 - 如果他们只使用返回键，而不是对页面上某些元素周围出现空格的原因感到困惑，会更容易。不过，这几乎总是在文本区域内，没有理由使用
I use line breaks when customers may be able to edit things - it's easier if they just use the return key rather than get confused as to why spaces appear around certain elements on the page. This is almost always within text areas though, there's no reason to position anything else using
<br />中断标记（单独使用时应为
必须用于中断一行而不是用于定位，特别是因为您仅中断单行。
它应该与您使用返回键具有相同的概念。
希望有帮助。
The break tag (that when used alone should be
<br />)Must be used to break a line not for positioning, specially since you break only single lines.
It should have the same concept behind as you use the return key.
Hope it helps.
我的意见：
（话虽如此，我偶尔也会使用它们来分隔段落）
My opinion:
(With that said, occasionally I use them for separating paragraphs, too)
