HTML Guide
The autocomplete attribute on an input, textarea, select or form element lets web developers specify how autocompleting should be handled.
The value none is not valid, instead the value off should be used to disable autocompletion.
Here is an example of how you can adjust your HTML code:
Incorrect usage:
<input type="text" name="username" autocomplete="none">
Correct usage:
If you want to disable autofill for an input field, you can use the value off instead of none:
<input type="text" name="username" autocomplete="off">
The attribute value is either the keyword off or on, or a space-separated token list that describes the meaning of the autocompletion value, for example name, email, postal-code and others. Refer to the linked guide to see the full list of accepted values for the autcomplete property.

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">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 value company is not a valid option for the autocomplete attribute on an <input> element. You may use the organization value instead, as it can be used for “company name corresponding to the person, address, or contact information in the other fields associated with this field”.
The value contact is not a valid option for the autocomplete attribute on an <input> element.
The text-anchor attribute is used within SVG elements like text or textPath to specify the alignment of text relative to a given point, but it’s not allowed on g container elements.
Here’s an example of how you can correctly use the text-anchor attribute on a <text> element in SVG:
<svg width="200" height="200">
<text x="100" y="100" text-anchor="middle">Centered text</text>
</svg>In this example:
- The text-anchor="middle" attribute is applied directly to the <text> element.
- It aligns the text in the middle horizontally around the specified x-coordinate.
You can use the text-anchor element with the SVG elements text, textPath, tref or tspan.
The allowed values for the text-anchor attribute are start, middle or end. The value none is not valid for this attribute.
The correct way to disable autocomplete is using the value off.
Example:
<form autocomplete="off">The correct way to disable autocomplete is using the value off.
Example:
<input type="text" name="firstName" id="firstName" required autocomplete="off" />The correct way to disable autocomplete is using the value off.
Example:
<input type="text" name="firstName" id="firstName" required autocomplete="off" />The value street-address cannot be used for attribute autocomplete on an <input> element. As this kind of autofill is oriented for multi-line inputs (as in the expected format for addresses), consider using a <textarea> element instead, like in this example:
<textarea name="address" autocomplete="street-address"></textarea>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" />
