让我们说:
.el {
background:linear-gradient(to bottom, black, black), linear-gradient(to bottom, red, red), linear-gradient(to bottom, blue, blue), linear-gradient(to bottom, green, green);
background-repeat:no-repeat;
background-position:0 0;
background-size:100% 0;
}
.el:hoover{
background-size:100% 100%;
}

没有其他div
/ ::before
/ ::after
是否可能?
