Vernacular: the so-called semantic label is the meaning of the indicator sign.

1. Purpose:

According to the semantics of the label, give the most reasonable label in the appropriate place to make the structure clearer. 1. Easy to read and maintain the code. 2. Use semantic tags for better SEARCH engine optimizationCopy the code

2. Good semantics:

When we remove CSS, the structure of the page remains well organized and readable. (It looks just as good naked)

3. Principles followed:

Decide on the semantic HTML first, then choose the appropriate CSS. So, we’re going to look at HTML tags and remember them semantically. The implementation of any element in an HTML web page depends on HTML tags.
