HTML Guide for none
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 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 padding CSS shorthand property sets the padding area on all four sides of an element at once.
To specify no padding, use padding: 0 instead of padding: none.
The value none is not a valid value for the vertical-align CSS property.
The vertical-align property in CSS is used to specify the vertical alignment of an inline or table-cell element. This property affects the alignment of elements that are placed next to each other in a line. Valid values for vertical-align include keywords like baseline, sub, super, text-top, text-bottom, middle, top, bottom, as well as length values (such as px, em) and percentage values. The value none is not recognized as a valid option for vertical-align, which is why the validator reports an issue.
Below are examples using valid values for the vertical-align property:
<!DOCTYPE html>
<html lang="en">
<head>
<title>Valid Vertical Align</title>
<style>
.aligned-text {
vertical-align: middle;
}
</style>
</head>
<body>
<table>
<tr>
<td style="vertical-align: top;">Top</td>
<td class="aligned-text">Middle</td>
<td style="vertical-align: bottom;">Bottom</td>
</tr>
</table>
</body>
</html>In the above example, each table cell is using a valid vertical-align value (top, middle, and bottom) to control vertical alignment. If you replace vertical-align: none; with one of these values according to your design requirements, your code will validate correctly.
