Strikethrough or line-through text using sIFR

I am using sIFR3-r436. I want to strikethrough or line-through some text. I have tried both <s>HTML</s开发者_开发知识库> and CSS: text-decoration:line-through but it won't work.

Here's my code.

css: ['.sIFR-root { font-size:28px;
line-height:36px; font-weight:bold;
color:#130f0e; text-align:center;
leading: 0; margin:0px; padding:0;
}','strong
{text-decoration:line-through;}']

Is there any solution for this?

sIFR 3 is based on Flash 8, which I believe does not support line-through.
