self-closing-void-elements

💅 The extends: 'stylistic' property in a configuration file enables this rule.

🔧 The --fix option on the command line can automatically fix some of the problems reported by this rule.

HTML has no self-closing tags. The HTML5 parser will ignore self-closing tag in the case of void elements (tags that shouldn't have a "closing tag"). Although the parser will ignore it, it's unnecessary and can lead to confusion with SVG/XML code.

Examples

This rule forbids the following:

<img src="http://emberjs.com/images/ember-logo.svg" alt="ember" />
<hr/>

This rule allows the following:

<img src="http://emberjs.com/images/ember-logo.svg" alt="ember">
<hr>

There may be cases where a self-closing tag may be necessary for void elements. In such cases, a require string may be passed to log the missing closing tags.

Configuration

The following values are valid configuration:

  • boolean -- true for enabled / false for disabled
  • string -- require to mandate the use of self closing tags
