Notes and Potential Issues

The following notes and warnings highlight missing or conflicting information which caused the validator to perform some guesswork prior to validation, or other things affecting the output below. If the guess or fallback is incorrect, it could make validation results entirely incoherent. It is highly recommended to check these potential issues, and, if necessary, fix them and re-validate the document.

  1. Info No Character encoding declared at document level

    No character encoding information was found within the document, either in an HTML meta element or an XML declaration. It is often recommended to declare the character encoding in the document itself, especially if there is a chance that the document will be read from or saved to disk, CD, etc.

    See this tutorial on character encoding for techniques and explanations.

Validation Output: 2 Errors

  1. Warning Line 183, Column 9: character "<" is the first character of a delimiter but occurred as data 
    Entrada <18 anos, >65 anos e estudantes: 1€<br />

    ✉

    This message may appear in several cases:

    • You tried to include the "<" character in your page: you should escape it as "&lt;"
    • You used an unescaped ampersand "&": this may be valid in some contexts, but it is recommended to use "&amp;", which is always safe.
    • Another possibility is that you forgot to close quotes in a previous tag.
