HTML Checking for Large Sites
Rocket Validator integrates the W3C Validator HTML checker into an automated web crawler.
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>Related W3C validator issues
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>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>
