HTML Checking for Large Sites
Rocket Validator integrates the W3C Validator HTML checker into an automated web crawler.
<select> elements that are required and are not multiple need a placeholder option that has no value, for example:
<select required>
<option value="">choose size</option>
<option value="s">small</option>
<option value="l">large</option>

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>When nesting a select element inside a label that has a for attribute, the id attribute of the select is required to match it.
The label element represents a caption in a user interface. The caption can be associated with a specific form control, known as the label element’s labeled control, either using the for attribute, or by putting the form control inside the label element itself.
When the select is inside the label, there’s no need to specify a for attribute as there can only be one select, as in this example:
<label>
Age
<select>
<option>young</option>
<option>old</option>
</select>
</label>However, if the for attribute is specified, then it must match the id of the select like this:
<label for="age">
Age
<select id="age">
<option>young</option>
<option>old</option>
</select>
</label>The <option> element no longer accepts a name attribute, which is now obsolete.
Example:
<select id="pet-select">
<option value="">--Please choose an option--</option>
<option value="dog">Dog</option>
<option value="cat">Cat</option>
<option value="hamster">Hamster</option>
