HTML issues tagged as whitespace.
The <label> element represents a caption in a document, and it can be associated with a form input using the for attribute, which must be an ID. Document IDs cannot contain whitespace.

<form>
<label for="user_name">Name</label>
<input type="text" id="user_name" />
