Element “title” must not be empty.

The <title> element, used to define the document’s title, is required and must not be empty.

Example:

<html>
  <head>
    <title>Automated Website Validator</title>
  </head>
  <body>
    <p>...</p>
  </body>
</html>

Element “head” is missing a required instance of child element “title”.

head
title

The <head> section of an HTML document contains metadata about the document, and as a minimum it must include a <title> tag defining the document title.

Common causes for this issue are forgetting to define the <title>, or duplicated <head> sections where one of them does not include the title.

Here’s an example of a minimal HTML document including the title:

<!DOCTYPE html>
<html>
  <head>
    <title>Don't panic! This is the title</title>
  </head>
  <body>
    <p></p>
  </body>
</html>

Element “option” without attribute “label” must not be empty.

Drop-down lists can be defined in HTML by using the <select> tag, containing the different <option>s. Each <option> must have a name, which can be either contained between <option> and </option>, or alternatively using the label attribute.

Example:

<select name="size">
  <option value="s">small</option>
  <option value="m" label="medium"></option>
</select>
