HTML Advantage
- All well-known browser vendors support!
- Microsoft
- apple
- Opera
- Mozilla firefox
- Many miscellaneous browser does not support HTML5
- Market demand
- The market needs a uniform standard :( expand) the nature of technology: money (Development)
- Web compatibility issues. Bug fixes require a lot of time
- Cross-platform (browser) B / S
- Naturally occurring, because it is a B / S to develop PC, mobile stations, and so on are all natural support! Hypertext markup language can be used on a wide range of platforms.
3.W3C standard
World Wide Web Consortium: a standard not a standard, but rather a collection of standards. The main page consists of three parts: structure (Structure), performance (Presentation) and behavior (Behavior).

4. common front-end development tools
- notebook
- Notepad++
- Sublime
- VScode (front-end specialty)
- WebStorm (front-end specialty) IDEA
- HBuilder (Professional)
Not the best tool, only the most appropriate
Technology no ranking points, only the use of technology level of the other people
