Reading notes:

This "HTML profiling" is biased towards the introduction of tags, and given the understandable and per-section space problem, I am not classified by the HTML of the blog, which makes it easier for you to select interesting tags, where only "file tags" are required and the rest are optional. This article will not mention any web editing software, as long as you have mastered HTML, any web editing tool can become a sharp weapon.

Tag notation:

Any markings are surrounded by "<" and ">", such as < P > No white-space characters can be left between the tag name and the less than sign. Some tags need to be added, and some do not. such as <font size= "+2" >Hello</font> Parameters can only be added to the start tag. The symbol "/" before the tag name of the starting tag is its end tag, such as </font> Tag letters can be both uppercase and lowercase.

Containment mark and empty tag:

Mark is divided into containment mark and empty mark by type Containment Mark As the name suggests, it surrounds the text with a start tag and an end tag to make it appear as expected. For example, HTML Source: <b> creation of webpage </b> is my favourite. Displayed: creation of webpage is my favourite. Where <b> </b> is called containment mark. It is displayed in bold with the start tag <b> and the end tag </b> marked text creation of webpage, which displays an error display in both cases. Empty tag Indicates that the tag appears alone, and that only the start tag has no end tag. For example, HTML Source: I Love creation of webpage. <br> It ' s a wonderful place. Show as: I Love creation of webpage. It ' s a wonderful place. The newline Mark <br> is an empty tag. Its role is to show everything after the mark on the next line, the visible end of the mark on it is meaningless, but some people will be the empty tag plus the end tag, which is convenient for token and has no effect on the HTML.
