Need help with weight painting and skinning!!

[TheGreatNoob]

Hello, I rigged a character and used skin modifier, so the biped can deform the mesh. But the animations are looking really weird. I know this can be fixed by editing envelopes or something like that lol. But I'm having a bad time in figuring out how weight painting and editing envelopes works 😞 .I tried editing envelopes and weight painting but its making it worse. And when I alt click to remove the paint, the blue areas kept growing, is that the way it should work? How white and blue areas affect the mesh ? Please expain me in detail how i can fix this.
