How to make a gradient fill for SVG?

Question

User interface

There is an svg icon in black color. How to make it not black, but a gradient? Worked only with raster graphics. Is it necessary to open a vector file, not svg , in Illustrator and fill it with a gradient there? Or can it be done with css ?

Answer 1

you need to open the search, not the illustrator:
