Hola ,hice todo lo ke me dijiste pero me da estos errores:
Below are the results of attempting to parse this document with an SGML parser.
Line 84, column 25: document type does not allow element "P" here; missing one of "APPLET", "OBJECT", "MAP", "IFRAME", "BUTTON" start-tag
<br><A href="#uno"><p>Diseño y creación de páginas Web.</p></a>
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 "<p>" or "<table>") inside an inline element (such as "<a>", "<span>", or "<font>").
