How to adjust gradient line to white

Quick answer：

To adjust a gradient line to white, you need to modify the color stops in the gradient definition. If you are using a programming language or a design tool, locate the gradient fill or stroke and change the color at the start and end stops to pure white (e.g., #FFFFFF or rgba(255, 255, 255, 1)). This will create a gradient that transitions from white to white, effectively making the line white.
