[xwiki-users] Adding css style to page

Hi Folks, I'm struggling with something I thought should be quite simple. I want to style a series of elements in a page (box macro) so want to just define a css style for this just for this one page. I was trying to set styles using html content like this: {{html}}<style> h1 {color:red;} p {color:blue;} </style> {{/html}} but the style definition is not getting included (though in other cases like this {{html}}<b>bold text</b>{{/html}} its working as expected). What am I doing wrong here? Thanks Tim
