HTML Code Style

Reference Code Standard

Google’s HTML guide
The Code Guide also provides excellent guidance for developing consistent, flexible, and sustainable HTML.

Implementing the Standard

We recommend using HTMLHint . You can install this as a plugin for your IDE or for the command-line:

Example .htmlhintrc:

{
  "alt-require": true,
  "attr-no-duplication": true,
  "attr-unsafe-chars": true,
  "attr-value-double-quotes": false,
  "attr-value-not-empty": false,
  "doctype-first": true,
  "doctype-html5": true,
  "head-script-disabled": false,
  "href-abs-or-rel": false,
  "html-lang-require": true,
  "id-class-ad-disabled": true,
  "id-class-value": false,
  "id-unique": false,
  "inline-script-disabled": false,
  "inline-style-disabled": false,
  "spec-char-escape": false,
  "src-not-empty": true,
  "style-disabled": false,
  "tag-pair": false,
  "tag-self-close": false,
  "tagname-lowercase": true,
  "title-require": true
}
