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
}
