You have used the attribute named above in your document, but the document type you are using does not support that attribute for this element. This error is often caused by incorrect use of the «Strict» document type with a document that uses frames (e.g. you must use the «Transitional» document type to get the «target» attribute), or by using vendor proprietary extensions such as «marginheight» (this is usually fixed by using CSS to achieve the desired effect instead). This error may also result if the element itself is not supported in the document type you are using, as an undefined element will have no supported attributes; in this case, see the element-undefined error message for further information. How to fix: check the spelling and case of the element and attribute, (Remember XHTML is all lower-case) and/or check that they are both allowed in the chosen document type, and/or use CSS instead of this attribute. If you received this error when using the element to incorporate flash media in a Web page, see the FAQ item on valid flash.

The mentioned element is not allowed to appear in the context in which you’ve placed it; the other mentioned elements are the only ones that are both allowed there and can contain the element mentioned. This might mean that you need a containing element, or possibly that you’ve forgotten to close a previous element.
One possible cause for this message is that you have attempted to put a block-level element (such as «
A table row was X columns wide, which is less than the column count established by the first row (Y).
A contains a row that has less columns than the column count established by the first row. Check the table to ensure all rows have the same number of columns.
For example, in the following table, the first row defines that it’s 2 columns wide, but the second row tries to use only 1 column:

Bad value X for attribute “media” on element “link”: Deprecated media feature “max-device-width”. For guidance, see the Deprecated Media Features section in the current Media Queries specification.
To query for the size of the viewport (or the page box on page media), the width, height and aspect-ratio media features should be used, rather than device-width, device-height and device-aspect-ratio, which refer to the physical size of the device regardless of how much space is available for the document being laid out. The device-* media features are also sometimes used as a proxy to detect mobile devices. Instead, authors should use media features that better represent the aspect of the device that they are attempting to style against.
The width media feature describes the width of the targeted display area of the output device. For continuous media, this is the width of the viewport including the size of a rendered scroll bar (if any).
In the following example, this media query expresses that the style sheet is only linked if the width of the viewport 768px maximum:

The aspect-ratio CSS property allows you to define the desired width-to-height ratio of an element’s box. This means that even if the parent container or viewport size changes, the browser will adjust the element’s dimensions to maintain the specified width-to-height ratio. The specified aspect ratio is used in the calculation of auto sizes and some other layout functions.
The box’s preferred aspect ratio is the specified ratio of width / height. If height and the preceding slash character are omitted, height defaults to 1.
A CSS definition for background-image could not be understood by the parser. Check its definition to ensure that it’s well formed and that it contains an appropriate value.
The hexadecimal value for the color CSS property is not valid. It needs to have either 3 or 6 hexadecimal digits.
The color CSS property sets the foreground color value of an element’s text and text decorations, and sets the currentcolor value. currentcolor may be used as an indirect value on other properties and is the default for other color properties, such as border-color.
This property accepts colors in different formats, one of them being hexadecimal values. For example a pure red color can be expressed either with 3 hexadecimal digits or 6 hexadecimal digits:
The value on the display property is not valid.
The display CSS property sets whether an element is treated as a block or inline element and the layout used for its children, such as flow layout, grid or flex.
