Re^2: Style Sheet Doesn't Display Styles

[JaredHess]

jdtoronto, thanks for replying.

I'm not sure if that's it, because it is finding the sheet sometimes.

In any case, I tried doing it with the initial slash (also tried an absolute pathway pointing to the .css), but neither improved performance.

I thought it might be a local webserver thing, so I uploaded it and the style sheet to our production server and get the same result.

One thing I noticed is that you don't close your <link> tag. Closing link tags is NOT optional in HTML. just re-read the specs, and in fact you're not allowed to use a closing link tag. please ignore

Another possibility is that your server isn't sending out the correct content-type header for the css.

In any case it's more likely an HTML/browser/server problem than a perl question :-)

Update: He corrected himself when I was writting my post. Ignore this post.

No, the closing tag is optional (in HTML 4.01). Note the "O" for "Optional":

<!ELEMENT LINK - O EMPTY               -- a media-independent link -->
<!ATTLIST LINK
  %attrs;                              -- %coreattrs, %i18n, %events -

Thanks for the correction, even though I found the error already :-)

I think I was confused with <script> tags.

[JaredHess]

Thanks Joost,

If this is indeed the case, how would I check it (not familiar with this... this is the first time I've tried to use style sheets in my perl scripts) and how would I correct it?

If you have firefox with the livehttpheaders extension you can see the headers of all requests.

you can also use the lwp-request command that comes with LWP. For example:

lwp-request -m HEAD http://localhost/

gives me:

The important part in this case is the Content-Type header. For a stylesheet it should say Content-Type: text/css optionally followed by a semi-colon and charset value - and a lwp-request <url> should give you the content of the stylesheet.

You could also try to see if making a plain HTML page containing the output of your script gives the same problem. Trying different browsers can also be enlightening.
