How to turn gradient color into white

Quick answer：

To turn a gradient color into white, you need to adjust the gradient's color stops. In most graphic design software, this can be done by selecting the gradient tool, then modifying the color stops at either end of the gradient. Set the color of the starting stop to white and the ending stop to white as well, ensuring the gradient transitions from white to white. If you are coding, you can use a linear gradient function with white as the start and end colors.
