If you want to generate codes like that (cross-browser codes), you can use from some short codes in PhpStorm. They are so useful and exist for HTML, CSS, JavaScript, SQL, PHP, Angular and so on.
To see them in your IDE, you can go to setting and then in the search box, write: "Live Templates" (It's located in the 'Editor' section).
