Element “script” must not have attribute “charset” unless attribute “src” is also specified.
Bad value “” for attribute “name” on element “input”: Must not be empty.
Attribute “value” not allowed on element “input” at this point.
Element “input” is missing required attribute “alt”.
The “center” element is obsolete. Use CSS instead.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
