no-non-scalable-viewport

This rule disallows the use of user-scalable=no in the <meta name="viewport">.

The user-scalable=no setting disables zooming on a page, which can make it difficult for users with partial or low vision to read the content.

How to use

.eslintrc.js

module.exports = {
  rules: {
    "@html-eslint/no-non-scalable-viewport": "error",
  },
};
