I tried to use SSX as best practise. I used below CSS3: .container-with-background { width: 100%; height: 500px; background-color: blue; background: url("$xwiki.getAttachmentURL($doc, ${xwiki.getDocument($doc).getObject('WaihonaCode.centresExpertiseClass').photo})") no-repeat center; background-size: cover; background-clip: padding-box; } Blue is just a color in this example, I Actually use a color related to the primary-color of color theme (flamingo) This works as long as $doc = page holding the SSX object. But I actually have a class, sheet and object page. So $doc in my case is the page holding the object. This returns a error: [Error] Failed to load resource: the server responded with a status of 404 (Not Found) ($xwiki.getAttachmentURL($doc, ${xwiki.getDocument($doc).getObject('WaihonaCode.centresExpertiseClass').photo}), line 0) The url generated is: ...ssx/space/($xwiki.getAttach...) Is there a way of accessing the variables required to call getAttachmentURL(); Full-doc name and a Object-property from the SSX? Or would it be, in this case, better to generate inline CSS in the sheet?

Hi,

I have a attached image on a page.

My aim is to use the image as a background image,

So the resulting HTML should be

<div style="background-image: url(http://i54.tinypic.com/4zuxif.jpg)"></div>

So in the HTML-macro I have a $doc.getAttachmentURL('xxx.png')

But executing it it looks like the wiki-engine is also transforming the "background-image:" as a wiki image, so I get resource not found errors?

Any suggestion how to wrap?

The best practice is to use a SSX: http://platform.xwiki.org/xwiki/bin/view/DevGuide/SkinExtensionsTutorial Note: Re the HTML macro please paste our exact content. The HTML macro will clean the HTML by default to make sure it generates valid XHTML. To prevent this cleanup , use clean=“false”. See the doc for the HTML macro for more details. Thanks -Vincent
