✪p+CSS" is actually an inaccurate name

At the beginning of the note, I must correct an error for everyone. The name "p+CSS" is actually an inaccurate name. It was given by the Chinese to this method of laying out standard pages. The name is caused by a lack of thorough understanding of the technology. What is the standard name? Haha, yes, the standard name is xHTML+CSS. Simply distinguish it from the code. The past

://m.sbmmt.com/code/7955.html" target="_blank">page layoutTable+CSS", and now the layout page uses p, so it's called "p+CSS". It sounds quite reasonable, but don’t you know that this term has misled most web developers and led web page makers into two major misunderstandings: [Myth 1] If Table is used in a web page, the page is not standard. , and even feel that it is embarrassing to use Table. Table has become the key point to determine whether the page is standard.

[Misunderstanding 2] It is believed that the more p tags used in a web page, the better. Some people even replace all tags in the page with p. The number of p determines the degree of page standard.

In order to avoid misunderstandings, you must understand the purpose of the two web page elements "Table" and "p". First of all, the purpose of Table is to store data, and the purpose of p is to set up Page structure, the two have different functions. When you need to store data, it is most convenient and quick to use Table. For example, a theme page "Browser Encyclopedia" of W3Cfun.com, the address is: http://www.w3cfuns. com/portal.php?mod=topic&topicid=6, Table is definitely the most appropriate at this time, and of course the part outside the table that makes up the page structure uses p. This is determined by the purpose of their birth, and it is also in line with W3C standards. , then this page is a standard page.

But p+CSS has been deeply rooted in the hearts of the people. Especially for a newbie like me, the name p+CSS is much more appropriate. Anyway, I will use p+ later. To explain it with the name CSS, whether it will mislead you is a matter of opinion, haha! I also want to comment: I guess after HTML5 becomes popular, will it be called section+css? Haha, what do you think?

✪What are W3C standards? The W3C standard is not a standard, but a collection of standards, including three parts of standards: structure standards, performance standards and action standards.

The representative language corresponding to the structure standard is xHTML, the representative language corresponding to the presentation standard is CSS, and the representative language corresponding to the action standard is JavaScript.

Okay, now that I’ve finished talking about the common sense about the web front-end, let’s start taking today’s notes. By the way, since I’m on winter vacation, I don’t seem to have much time to write a blog, haha, you know.

In the CSS layout method, p is the core object of this layout method, and our page layout no longer relies on tables. Just from the use of p, making a simple layout only requires two things: p and CSS. Therefore, we call this layout method p + CSS layout.

p is a container tag specified in XHTML and specifically used for layout design. Elements used to store html elements, text, pictures, and videos. Content styles are specified by CSS.

CSS (Cascading Style Sheet) is a standard way to format web pages and is used to control web page styles. A technology that allows style information to be separated from web content.
