Dazu noch die fehlermeldung
Line 96, Column 63: there is no attribute "target
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 <embed> element to incorporate flash media in a Web page, see the FAQ item on valid flash.
Line 80, Column 25: there is no attribute "align"
Line 76, Column 20: there is no attribute "border"
EDIT:ich glaub jetzt erkenne ich denn fehler erst .Ich hab HTML mit design vermischt oder?was man ja nicht macht HTML dann design mit CSS ?
