Bad value “street-address” for attribute “autocomplete” on element “input”: The autofill field name “street-address” is not allowed in this context.

The autocomplete attribute is used to control if the browser can provide assistance in filling out form field values, and it only makes sense for visible, not hidden, inputs.

It is available on <input> elements that take a text or numeric value as input, <textarea> elements, <select> elements, and <form> elements.

To fix this issue, you can remove the autocomplete attribute from the input element with type=hidden. Here is an example:

<!-- Wrong code -->

<input type="hidden" name="phone" value="12345" autcomplete="off">

<!-- Correct code -->

<input type="hidden" name="phone" value="12345">

An empty string is not a valid value for the autocomplete attribute on an input element.

The autocomplete attribute controls whether the browser can autofill input values, and it requires a valid, non-empty value according to the HTML specification. Acceptable values are on, off, or specific autocomplete tokens such as name, email, username, etc. Leaving it empty, like autocomplete="", causes validation errors.

Incorrect example:

<input type="text" name="username" autocomplete="">

Correct examples: Enable browser autocomplete:

<input type="text" name="username" autocomplete="on">

Disable browser autocomplete:

<input type="text" name="username" autocomplete="off">

Use a specific token (recommended for forms that collect particular data):

<input type="email" name="useremail" autocomplete="email">

The value tel-national cannot be used on the attribute autocomplete of an <input> element of type tel. Either change to type="text", or use autocomplete="tel". Examples:

<!-- Using autocomplete "tel-national" on type "tel" is invalid -->

<input name="phone1" type="tel" autocomplete="tel-national" />

<!--Using autocomplete "tel-national" on type "text" is valid -->

<input name="phone2" type="text" autocomplete="tel-national" />

<!--Using autocomplete "tel" on type "tel" is valid -->

<input name="phone3" type="tel" autocomplete="tel" />

The aria-* attributes are part of the WAI-ARIA (Web Accessibility Initiative-Accessible Rich Internet Applications) suite. They are used to improve the accessibility of web pages. However, when we use an input element with a type attribute whose value is hidden, we imply that the element is invisible and has no interaction with the user. Therefore, it doesn’t make sense to add aria-* attributes to it.

To fix this issue, you need to remove the aria-* attributes from the input element with type=hidden. Here is an example:

<!-- Wrong code -->

<input type="hidden" name="referer" value="https://example.com" aria-invalid="false">

<!-- Correct code -->

<input type="hidden" name="referer" value="https://example.com">

When nesting an input element inside a label that has a for attribute, the id attribute of the input 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 input is inside the label, there’s no need to specify a for attribute as there can only be one input, as in this example:

<label>
  Age
  <input type="text" name="age">
</label>

However, if the for attribute is specified, then it must match the id of the input like this:

<label for="user_age">
  Age
  <input type="text" name="age" id="user_age">
</label>

The autocomplete attribute is not valid on input types that do not return numeric or text data, being valid for all input types except checkbox, radio, file, or any of the button types.

The maxlength attribute can be used on an input element to define a client-side validation for the maximum length allowed on an input without resorting to JavaScript.

This attribute is only allowed on elements of type email, password, search, tel, text, or url.

The minlength attribute can be used on an input element to define a client-side validation for the maximum length allowed on an input without resorting to JavaScript.

This attribute is only allowed on elements of type email, password, search, tel, text, or url.

The minlength attribute defines the minimum number of characters (as UTF-16 code units) the user can enter into an <input> or <textarea>. This must be an integer value 0 or higher. If no minlength is specified, or an invalid value is specified, the input has no minimum length. This value must be less than or equal to the value of maxlength, otherwise the value will never be valid, as it is impossible to meet both criteria.

Here’s an example:

<label for="name">Enter your name (max 25 characters)</label>
<input type="text" minlength="25" id="name">

The pattern attribute is only allowed on input whose type is email, password, search, tel, text or url. Check the type used, and consider changing to one of the allowed types to enable pattern client-side validation.

The pattern attribute is a handy way of adding client-side validation on HTML forms without resorting to JavaScript. Check out this article to learn more about Input Pattern.

The <textarea> element does not have a type attribute.

The HTML <textarea> element represents a multi-line plain-text editing control, and is useful when you want to allow users to enter a sizeable amount of free-form text, for example a comment on a review or feedback form.
