This article mainly introduces some basic things about html paragraphs p tags. Beginners can take a look. If you want to learn more deeply, you are welcome to come in and click on the bottom of the article about html paragraphs. The advanced version of the P tag, well, this article introduces the basic understanding of the HTML paragraph p tag. I hope you will read it carefully. I have explained it in as much detail as possible.
html Definition and usage of p tag:
tag definition paragraph.
p elements automatically create some whitespace before and after them. The browser adds these spaces automatically, or you can specify them in your stylesheet.
hc Obviously, it is wrong to understand P as inline. There can be many lines in P, and it cannot be said to be an inline element. The reason it's called a block is that it has its own things like line-height that line elements don't have. Obviously,
and so on can be called inline elements, but it is inappropriate to call P. And the block here does not refer to the block of content. Rather refers to a block of text or a stream of text. In other words, P represents a text stream. DIV is not only a block on the text flow, but also forms an area block on the display. So it is appropriate to call DIV a block or block!
So as far as text flow is concerned, P is a block element. As far as the entity performance of HTML is concerned. DIV is a block (block) element that forms a block! But in actual use, there is no need to distinguish them clearly! The reason why most textbooks still call P a block element is because it is unfounded and inappropriate to call it an inline element.
HTML Tag Example
The following code marks a paragraph:
<p>这是一个段落。</p>
Tag defines a paragraph.
The standard specification is:
As for not being paired, we can only say that it does not meet the specification
But I didn’t say it Definitely not, maybe due to the fault tolerance of the browser, etc., it can still display normally
But when writing code, it is best to abide by the specifications, which has great benefits
Follow the specifications , it can run normally under any circumstances
If it does not follow the specifications, then it will be fine if it can work normally in a certain environment. If it is not normal, wouldn't it mean that the program needs to be modified again? Damn trouble!
p elements automatically create some whitespace before and after them. The browser adds these spaces automatically, or you can specify them in your stylesheet.
The paragraph spacing
IE defaults to 19px, set by the margin-top attribute of p
FF defaults to 1.12em, set by the margin-bottom attribute of p
pThe default is block display. To clear the paragraph spacing, you can generally set it
p { margin-top:0; margin-bottom:0; }
Extended reading: Allowed usage of html paragraph tag
You can specify paragraph
only within a block, or you can use paragraph
with other paragraphs, lists, forms, and pre-formatted text. In general, this means that the paragraph
can appear anywhere there is appropriate text flow, such as in the body of the document, within the elements of a list, etc.
From a technical point of view, the paragraph
cannot appear in the header, anchor, or other places that strictly require the content to be text only. In fact, most browsers ignore this restriction and format the paragraph
along with the content of the containing element.
