Validering av XHTML

**Hejsan!

Jag försöker validera min sida, men möts av detta felmedelande:**

# Error Line 9 column 21: required attribute "alt" not specified.

<img src="logga.jpg"/>

The attribute given above is required for an element that you've used, but you have omitted it. For instance, in most HTML and XHTML document types the "type" attribute is required on the "script" element and the "alt" attribute is required for the "img" element.

Typical values for type are type="text/css" for <style> and type="text/javascript" for <script>.

<img src="diplom.jpg"/>

✉
# Error Line 24 column 5: end tag for "br" omitted, but OMITTAG NO was specified.

<br>

You may have neglected to close an element, or perhaps you meant to "self-close" an element, that is, ending it with "/>" instead of ">".

<SCRIPT LANGUAGE="JavaScript">

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.

<SCRIPT LANGUAGE="JavaScript">

You have used the element named above in your document, but the document type you are using does not define an element of that name. 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 "Frameset" document type to get the "\<frameset\>" element),
\* by using vendor proprietary extensions such as "\<spacer\>" or "\<marquee\>" (this is usually fixed by using CSS to achieve the desired effect instead).
\* by using upper-case tags in XHTML (in XHTML attributes and elements must be all lower-case.

<img src="logga.jpg" alt="" />
ska det vara... står ju i felmeddelandet...
<br> skrivs: <br />

javascriptet saken däremot vet jag inte (brukar inte köra sånt :P)

Kan vara att du skriver med Uppercase när allt ska skrivas med Lower Cases (dvs inga versala tecken).

1. ha med alt i alla img-element.

<img src="foo.gif" alt="en foo-bild"/>

2. avsluta alla <br>.

<br/>

3. case sensitive?

<script language="javascript">

@nders för långsam :P *yes*

Ska inte javascriptstaggen skrivas
<script type="text/javascript">whatever</script>
?
