Today I saw a cool login button effect on the Internet; it felt awesome at first glance; but after putting it aside bit by bit, I found that it is not that difficult; I will post all the code ; If there is anything wrong, please tell me.
Let’s put aside the before; in fact, the principle is to achieve the color gradient effect through the background size and matching position.
This effect won’t be so cool, or flashy; I think if When writing some effects, this should be more suitable, and then just match the colors you need.
