Caido.io HTML Check

HTML Validation Tool

Errors

Element “meta” is missing required attribute “content”.

An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.

The first child “option” element of a “select” element with a “required” attribute, and without a “multiple” attribute, and without a “size” attribute whose value is greater than “1”, must have either an empty “value” attribute, or must have no text content. Consider either adding a placeholder option label, or adding a “size” attribute with a value equal to the number of “option” elements.

Bad value “40vw” for attribute “width” on element “img”: Expected a digit but saw “v” instead.

Attribute “referrerpolicy” not allowed on element “script” at this point.

Warnings

The “type” attribute for the “style” element is not needed and should be omitted.

The “type” attribute is unnecessary for JavaScript resources.
