Adding bevel and emboss to an SVG element? - css

Question

So I was wondering if it was possible to add bevel and emboss to an SVG element?
My CSS for my rectangle element is like this:
rect {
fill: #e8e9eb;
stroke: black;
stroke-width: 1px;
width: 70;
height: 30;
}
and I was trying to add this CSS to it taken from here:
-webkit-box-shadow: inset 0 1px 0 rgba(255,255,255,.5), inset 0 -2px 0 rgba(0,0,0,.25), inset 0 -3px 0 rgba(255,255,255,.2), 0 1px 0 rgba(0,0,0,.1);
-moz-box-shadow: inset 0 1px 0 rgba(255,255,255,.5), inset 0 -2px 0 rgba(0,0,0,.25), inset 0 -3px 0 rgba(255,255,255,.2), 0 1px 0 rgba(0,0,0,.1);
box-shadow: inset 0 1px 0 rgba(255,255,255,.5), inset 0 -2px 0 rgba(0,0,0,.25), inset 0 -3px 0 rgba(255,255,255,.2), 0 1px 0 rgba(0,0,0,.1);
I believe the reason it isn't working is because it uses fill as opposed to a background but I'm not sure. Is there a way to do this while using the fill CSS style? If not, what would be the best way?

You want to use SVG Filter effects to bevel arbitrary SVG Content.
Here's an example with two versions of a bevel:
http://jsfiddle.net/rcd5L/
<svg xmlns="http://www.w3.org/2000/svg" viewBox="-10 -10 120 100">
<filter id="Bevel" filterUnits="objectBoundingBox" x="-10%" y="-10%" width="150%" height="150%">
<feGaussianBlur in="SourceAlpha" stdDeviation="3" result="blur"/>
<feSpecularLighting in="blur" surfaceScale="5" specularConstant="0.5" specularExponent="10" result="specOut" lighting-color="white">
<fePointLight x="-5000" y="-10000" z="20000"/>
</feSpecularLighting>
<feComposite in="specOut" in2="SourceAlpha" operator="in" result="specOut2"/>
<feComposite in="SourceGraphic" in2="specOut2" operator="arithmetic" k1="0" k2="1" k3="1" k4="0" result="litPaint" />
</filter>
<filter id="Bevel2" filterUnits="objectBoundingBox" x="-10%" y="-10%" width="150%" height="150%">
<feGaussianBlur in="SourceAlpha" stdDeviation="0.5" result="blur"/>
<feSpecularLighting in="blur" surfaceScale="5" specularConstant="0.5" specularExponent="10" result="specOut" lighting-color="white">
<fePointLight x="-5000" y="-10000" z="0000"/>
</feSpecularLighting>
<feComposite in="specOut" in2="SourceAlpha" operator="in" result="specOut2"/>
<feComposite in="SourceGraphic" in2="specOut2" operator="arithmetic" k1="0" k2="1" k3="1" k4="0" result="litPaint" />
</filter>
<rect width="100" height="40" filter="url(#Bevel)" />
<rect y="50" width="100" height="40" filter="url(#Bevel2)" />
</svg>

Also try using this if you want this kind of beveling
<svg xmlns="http://www.w3.org/2000/svg" viewBox="-10 -10 120 100">
<filter id="filter1" >
<feFlood flood-color="black" result="COLOR-red" />
<feMorphology operator="dilate" radius="0" in="SourceAlpha" result="STROKE_10" />
<feConvolveMatrix order="8,8" divisor="1"
kernelMatrix="1 0 0 0 0 0 0 0 0 1 0 0 0 0 0 0 0 0 1 0 0 0 0 0 0 0 0 1 0 0 0 0 0 0 0 0 1 0 0 0 0 0 0 0 0 1 0 0 0 0 0 0 0 0 1 0 0 0 0 0 0 0 0 1" in="STROKE_10" result="BEVEL_20" />
<feOffset dx="1" dy="1" in="BEVEL_0" result="BEVEL_25"/>
<feComposite operator="out" in="BEVEL_25" in2="STROKE_10" result="BEVEL_30"/>
<feComposite in="COLOR-red" in2="BEVEL_30" operator="in" result="BEVEL_40" />
<feMerge result="BEVEL_50">
<feMergeNode in="BEVEL_40" />
<feMergeNode in="SourceGraphic" />
</feMerge>
</filter>
<rect width="100" height="40" filter="url(#filter1)" />
<path x="50" y="50" fill="#3182bd" d="M9.184850993605149e-15,-150A150,150 0 0,1 140.95389311788625,-51.30302149885031L0,0Z" filter="url(#filter1)"></path>
</svg>
