I have an SVG image which I would like to change from a block colour to a gradient. I have got this working, however I would like to have a transition or animation. Is this possible - if so how would it be achieved?
HTML:
<svg width="96px" height="96px" viewBox="0 0 512 512" enable-background="new 0 0 512 512" xml:space="preserve">
<defs>
<linearGradient id="gradient" gradientUnits="userSpaceOnUse" fy="90%" >
<stop offset="0" style="stop-color:#1EBEE0"/>
<stop offset="1" style="stop-color:#952491"/>
<animate attributeName="fy"from="0" to="1" dur="5s" repeatCount="indefinite" />
</linearGradient>
</defs>
<path id="time-3-icon" d="M256,50C142.229,50,50,142.229,50,256c0,113.77,92.229,206,206,206c113.77,0,206-92.23,206-206

</svg>
CSS:
svg {
fill: blue;
transition: all 0.3s ease;
display: inline-block;
-webkit-transition: fill .4s ease;
-moz-transition: fill .4s ease;
-o-transition: fill .4s ease;
transition: fill .4s ease;
}
svg:hover {
fill: url(#gradient);
}
Any pointers would be much appreciated!
You can avoid using two rects by transitioning the stop-color
s instead:
svg { display: inline-block; } stop { -webkit-transition: .4s ease; transition: .4s ease; } /* Use the colors to transition to */ svg:hover stop:first-child { stop-color: #1EBEE0; } svg:hover stop:last-child { stop-color: #952491; }

Here's a demo of the technique using a simplified shape (no mask required).
Put the two fill styles on overlapping <rect>
objects, and use the clock icon as a mask object applied to both <rect>
objects. You can then animate the apparent fill style by animating the opacity of the uppermost <rect>
. Remember to apply a white fill to the mask object (white=opaque, black=transparent).
If the following snippet doesn't work, try this jsfiddle link .
#clock-gradient { opacity: 0.0; display: inline-block; -webkit-transition: opacity .4s ease; -moz-transition: opacity .4s ease; -o-transition: opacity .4s ease; transition: opacity .4s ease; } #clock-gradient:hover { opacity: 1.0; }
