The to- stop has a value of transparent to allow the second gradient to show through below it—remember, ... background-image: -webkit-gradient(linear, left top, right bottom, from( black), color-stop(50%, white), to( transparent)), -webkit-gradient(linear, right top, left bottom, from( black), color-stop(50%, ... start-point, end-point, from( from-stop), color-stop(color-stop), to( to-stop); }The immediate point of interest is that, as mentioned in the introduc-tion to this chapter, you have to specify the type...
