"HTML" Web semantics

I. Problem solving & Evaluation criteria

Web semantics can solve the following problems:

1. Missing page style

2. Visitors with color or other obstacles can also read the page

3. Mobile Device Access page

4. Programs (such as crawlers) understand the page (in other words SEO optimization)

Ii. Evaluation Criteria

Web semantics is mainly to make the page structure clearer, more attention to the hierarchical relationship between content and meaning. such as a div inside the title with H1 ~ h6, content is artical or section to wrap.

Web semantics in my Eyes is a Web page to remove CSS JS, people can still understand the meaning of the page, and further is the machine can recognize the page logic and meaning. For example, remove the page style can still understand H1~h6 is the title, div or artical or section is the content.

Third, how to achieve

How Web semantics are implemented, steps are as follows:

1. Select the appropriate HTML tags according to the content, such as header, footer, aside, nav, article, section, UL, Li (remember to distinguish Div, section, article OH)

2. Class ID naming and content, meaning combined (convenient CSS JS developers)

Four, the existing difficulties

1. Semantics does not have a very perfect norm, the research is not clear, has the H5 only then really starts to have the real meaning
