< p为H.和< div>和休息 [英] <p> and <div> and breaks
问题描述
1。这是来自W3C推荐页面的一些html。
< P> aaaaaaaaa< DIV> bbbbbbbbb< / DIV>< DIV> cccccccc< P> dddddddd< / DIV>
2.虽然我认为它不会产生任何影响,但我还是尝试了包含< / p>的
。
< P> aaaaaaaa< / p>< DIV> bbbbbbbbb< / DIV>< DIV> cccccccc< P> dddddddd< / p>< / DIV>
FF2将#1和#2都表示为:
------------------
aaaaaaaaa / br / >
bbbbbbbbb
cccccccc
dddddddd
所以它看起来像FF2没什么在< div>中允许< por< p> s
内的< div>还有其他解释吗? FF是< pterminates之后的双重休息时间(< br>< br>>)< pand另一次单独休息之后的单个
休息时间在以下之前
< div>。第二个< divbe在点击< p>时会终止吗?它看起来像是
。
W3C说大多数浏览器会将第一个浏览器显示为:
----- -----------------
aaaaaaaaa
bbbbbbbbb
cccccccc
dddddddd
.... IE7如何显示它。
IE7将#2呈现为:
-----------
aaaaaaaaa
bbbbbbbbb
cccccccc
dddddddd
看起来在IE7中,< pCAN包含一个< divwhich,当我们添加#1和#2时,它们占据了
的差异< / p> s。 < pin#1
可能不会结束,直到它击中第二个< p> ;.
我对这些结果感到惊讶。

根据HTML规范,< / ptag在经典
(基于SGML)HTML中始终可以省略,并且始终需要(对于XHTML中的< pelement)。当
可以省略时,遗漏不应该对意义或渲染产生任何影响。
但那不是浏览器(又称wowsers或tag slurpers)表现。只需
就可以了。如果您使用经典,请使用< / peven HTML(你应该这样做,除非你知道你从XHTML得到的一些实际好处),因为这样,
浏览器行为更容易预测。
< blockquote class =post_quotes>
FF2将#1和#2都表示为:
那么什么?
所以看起来FF2在< div>中< por< p> s
内不允许< div> s ???
什么?什么意思不允许什么?它是HTML
规范,不允许< divwithin< p> ;.
FF是
在< pterminates或< br>< br>之后< pand< pand< pand>之后的另一次单独休息之后< br>< br>>
< div>。第二个< divbe在点击< p>时会终止吗?它好像是b $ b。
停止猜测。查找关于HTML的教程并阅读有关标签和元素的内容。
如果问题仍然存在,请回来。
W3C表示大多数浏览器都会显示第一个:
什么?哪里?我们是否应该猜测你读哪个文件的哪一部分?
一般来说,W3C文件对浏览器的评价部分过时了,部分是
刚刚制作 - (也许是一厢情愿的想法),并且部分正确。

肯特,
忘掉休息时间。忘了< br>。他们只会让你感到困惑。
只要你想让段落
打破下一个段落,就可以在段落中单独添加一个< br>线。否则,永远不会。忘记它们,以及
它们之间的间距。
您所看到的,或者至少在看,是< p> ;
元素会自动终止。当浏览器通过aaa'读取
时,准备渲染< p>,它会碰到< div>
并意识到它应该终止段落并开始一个新的块
项目,div。
阅读< http://www.w3.org/TR/html4/intro /sgmltut.html#h-3.2.1> ;.
现在,*它发生*个别浏览器在某些特定浏览器之前和之后具有某些默认的垂直
间距元素,包括< pand< div>,和
*它们发生在几个浏览器中似乎很常见,
它也可能*看起来像*虽然间距相当于插入< brinto源的
结果,但是忘了这一切。只需
标记内容,并为你想要的间距设置元素的样式。
第二个< divbe可以在点击< p>?时终止它好像是b $ b看起来像。
我认为div没有终止,但是段落正在开始。您的
浏览器可能在< p>之前有一个默认的垂直间距。在那里。
>
看起来在IE7中< pCAN包含< div>
我不这么认为。 < divis块级标记。但< pcannot包含
块级元素:

我不知道为什么IE6和IE7不同,确切地说,但不同
浏览器是不同的。你是怪异模式吗?或者是什么?

1. Here''s some html from a W3C recommendations page.
<P>aaaaaaaaa<DIV>bbbbbbbbb</DIV><DIV>cccccccc<P>dddddddd</DIV>
2.Although I didn''t think it would make any difference, I tried it
with the </p>s included as well.
<P>aaaaaaaaa</p><DIV>bbbbbbbbb</DIV><DIV>cccccccc<P>dddddddd</p></DIV>
FF2 renders both #1 and #2 as:
------------------
aaaaaaaaa
bbbbbbbbb
cccccccc
dddddddd
So it looks like FF2 doesn''t allow either <div>s within a <por <p>s
within a <div>??? Is there some other explanation? FF is either
putting a double break (<br><br>) after the <pterminates or a single
break after the <pand another single break before the following
<div>. Could the second <divbe terminating when it hits the <p>? It
looks like it.
W3C says that most browsers will show the first one as:
----------------------
aaaaaaaaa
bbbbbbbbb
cccccccc
dddddddd
....which is how IE7 shows it.
IE7 renders #2 as:
-----------
aaaaaaaaa
bbbbbbbbb
cccccccc
dddddddd
It looks like in IE7 a <pCAN contain a <divwhich accounts for the
difference between #1 and #2 when we add the </p>s. The <pin #1
probably doesn''t end until it hits the second <p>.
I was surprised by these results.

2.Although I didn''t think it would make any difference, I tried it
with the </p>s included as well.By HTML specifications, the </ptag is always omissible in "classic"
(SGML-based) HTML and always required (for a <pelement) in XHTML. When
omissible, the omission should not have any effect on meaning or rendering.
But that''s not how browsers (a.k.a. wowsers or tag slurpers) behave. Just
live with it. Use </peven if you use "classic" HTML (as you should, unless
you _know_ some actual benefit that you get from XHTML), because that way,
browser behavior is more predictable.
FF2 renders both #1 and #2 as:So what?
So it looks like FF2 doesn''t allow either <div>s within a <por <p>s
within a <div>???What?? What do you mean by not allowing something? It''s the HTML
specifications that disallow <divwithin <p>.
FF is either
putting a double break (<br><br>) after the <pterminates or a single
break after the <pand another single break before the following
<div>. Could the second <divbe terminating when it hits the <p>? It
looks like it.Stop guessing. Find a tutorial on HTML and read about tags and elements.
Then come back if problems remain.
W3C says that most browsers will show the first one as:What? Where? Are we supposed to guess which part of which document you read?
Generally, what the W3C documents say about browsers is partly dated, partly
just made-up (wishful thinking perhaps), and partly correct.

<div>.Kent,
Forget about breaks. Forget about <br>. They are just confusing you.
Add a <br>, singly, inside a paragraph, only if you want the paragraph
to break to the next line. Otherwise, never. Forget about them, and the
spacing-ness of them.
What you are seeing, or at least looking at, is the case where <p>
elements are automatically terminated. When the browser is reading
through the aaa''s, preparing to render that <p>, it bumps into a <div>
and realizes it should terminate the paragraph and start a new block
item, the div.
Read <http://www.w3.org/TR/html4/intro/sgmltut.html#h-3.2.1>.
Now, *it happens* that individual browsers have certain default vertical
spacings before and after certain elements, including <pand <div>, and
*it happens* that these may appear to be common among several browsers,
it may also *look* as though the spacing is the equivalent of, say, the
result of inserting <brinto the source, but FORGET ALL OF THAT. Just
mark up the content, and style the elements for the spacing you''d like
to recommended.
Could the second <divbe terminating when it hits the <p>? It
looks like it.
I think the div isn''t terminating, but a paragraph is starting. Your
browser probably has a default vertical spacing before the <p>. There it is.
>
It looks like in IE7 a <pCAN contain a <div>I don''t think so. <divis block-level markup. But a <pcannot contain
block-level elements:
http://www.w3.org/TR/html4/struct/text.html#edef-P
I don''t know why IE6 and IE7 are different, exactly, but different
browsers are, well, different. Are you in quirks mode? Or what?
