I want to apply the following filter to some link element in my html page: My web page running on Chrome. (I found that filter somewhere on the net)
<filter id="tf" filterRes="172"> 
    <feImage xlink:href="noise.jpg"> 
    <feComposite in2="SourceGraphic" operator="arithmetic" k1="1"> 
    <feMorphology operator="erode" radius="30"> 
</filter>
I got the noise.jpg as a file in the root folder (where my index.html is)
The css is embedded in the html.index by the
styleelement
In what file extension the filter should be saved?
How can I refer to that file in the css code?
