Web Front-end Study Notes (Part 1) HTML

Starting today, I will write my study notes, limited to front-end, three basic programming, HTML CSS JavaScript;

I will not write about how html is formed and how it will develop in the future. I only recommend the book "The third edition of the HTML authoritative guide". I can find answers to the above questions.

The entire HTML page consists of four parts: doctype HTML head body. The following are precautions:

1: doctype: it does not belong to a tag. The doctype attribute is only declared. This is the Shenma document, XHTML, or HTML. Now the most commonly used is XHTML 1.0 transitional/en.

2: for the compilation of XHTML, note that all labels must be in lower case and close tags exist. For example: <p></P>.

3: HTML: The standard pointing to W3C organizations. xmlns = "htpp: // www.w3.org/5o/xhtml"

4: Head: the header, including the title, style, script, keyword, and encoding format.

5: Body: contains the content you need to write.

In normal cases, the <meta> label is required for encoding and other information settings, but the vsplatform has already been added automatically. Therefore, in most cases, no modification is required.

6: HTML comment: <! -- XXX -->

7: [place the link tag in the header of the page and the script tag before the end of the body .]

8: semantics, such as title Http://www.w3.org/
