Usando bússola e sass você pode facilmente conseguir isso da seguinte maneira:
@import "compass";
#border-radius {
@include border-radius('RADIUS'px); }
#gradiant{
$experimental-support-for-svg: true;
@include background-image(linear-gradient('COLOR') %,('COLOR') %,...; }
O Compass irá gerar uma imagem SVG para você.
igual a:
#gradiant {
background-image: url('data:image/svg+xml;base64,PD94bWwgdmVyc2lvbj0iMS4wIiBlbmNvZGluZz0idXRmLTgiPz4gPHN2ZyB2ZXJzaW9uPSIxLjEiIHhtbG5zPSJodHRwOi8vd3d3LnczLm9yZy8yMDAwL3N2ZyI+PGRlZnM+PGxpbmVhckdyYWRpZW50IGlkPSJncmFkIiBncmFkaWVudFVuaXRzPSJ1c2VyU3BhY2VPblVzZSIgeDE9InRvIiB5MT0iYm90dG9tIiB4Mj0idG8iIHkyPSJ0b3AiPjxzdG9wIG9mZnNldD0iMCUiIHN0b3AtY29sb3I9IiMwODJhMmUiLz48c3RvcCBvZmZzZXQ9IjM1JSIgc3RvcC1jb2xvcj0icmdiYSg4LCA0MiwgNDYsIDAuNzYpIi8+PHN0b3Agb2Zmc2V0PSI0MyUiIHN0b3AtY29sb3I9InJnYmEoNywgNDMsIDQ3LCAwLjcxKSIvPjxzdG9wIG9mZnNldD0iNTglIiBzdG9wLWNvbG9yPSJyZ2JhKDQsIDQ0LCA1MCwgMC41OCkiLz48c3RvcCBvZmZzZXQ9IjEwMCUiIHN0b3AtY29sb3I9IiMwNDJjMzIiLz48L2xpbmVhckdyYWRpZW50PjwvZGVmcz48cmVjdCB4PSIwIiB5PSIwIiB3aWR0aD0iMTAwJSIgaGVpZ2h0PSIxMDAlIiBmaWxsPSJ1cmwoI2dyYWQpIiAvPjwvc3ZnPiA=');
