    You could try making the background much larger and animating the background-position instead? Here's a good generator https://www.gradient-animator.com/, you can play around with it to see if you can get the effect you're looking for.

I achieve this by making the gradient a repeating gradient, but only using 1 quarter of the full gradient (0% through 25%) That is done by the calc() code



I need thirds for the second term, because you have 3 color stops (last one is equal to first one).



Then I scale the background by 4 (opposite of 1 quarter from above).



I can then animate the background-position

      I achieve this by making the gradient a repeating gradient, but only using 1 quarter of the full gradient (0% through 25%) That is done by the calc() code



      I need thirds for the second term, because you have 3 color stops (last one is equal to first one).



      Then I scale the background by 4 (opposite of 1 quarter from above).



      I can then animate the background-position

        I achieve this by making the gradient a repeating gradient, but only using 1 quarter of the full gradient (0% through 25%) That is done by the calc() code



        I need thirds for the second term, because you have 3 color stops (last one is equal to first one).



        Then I scale the background by 4 (opposite of 1 quarter from above).



        I can then animate the background-position
