It allows you to specify one or more <code>exact</code> string values from which one must be the parameter's value, or a set of <code>ideal</code> values which should be used if possible. You can also specify a single string (or an array of strings) which the user agent will do its best to match once all more stringent constraints have been applied.", "sections": [{"id": "Quick_Links", "title": null}, {"id": "Properties", "title": "Properties"}, {"id": "Specifications", "title": "Specifications"}, {"id": "Browser_compatibility", "title": "Browser compatibility"}, {"id": "See_also", "title": "See also"}], "slug": "Web/API/ConstrainDOMString", "review_tags": []}
