Code interpretation
There is no dom element, just write css.
Set up the page space:
Body {
Position:fixed
Margin:0
Width:100vw
Height:100vh
}
Set the background pattern with pseudo elements:
Body::before {
Content:''
Position:fixed
Width:200vmax
Height:200vmax
Background-color:steelblue
Color:turquoise
Background-image:
Linear-gradient (
45deg
CurrentColor25%
Transparent25%,transparent75%
CurrentColor75%)
Linear-gradient (
45deg
CurrentColor25%
Transparent25%,transparent75%
CurrentColor75%)
Background-position:00,5vmax5vmax
Background-size:10vmax10vmax
Pan the background pattern:
Body::before {
Top:50%
Left:50%
Animation:
9smoveinfiniteease-in-outalternate
}
@ keyframesmove {
From {
Left:-40%
Top:-40%
}
To {
Left:-60%
Top:-60%
}
}
Let the background pattern rotate:
Body::before {
Animation:
9smoveinfiniteease-in-outalternate
9s-1.5srotatinginfiniteease-in-outalternate
}
@ keyframesrotating {
To {
Transform:rotate (180deg)
}
}
Pan the page:
Body {
Top:50%
Left:50%
Animation:
3smoveinfiniteease-in-outalternate
}
Zoom the page:
Body {
Animation:
3smoveinfiniteease-in-outalternate
3szoominfiniteease-in-outalternate
}
@ keyframeszoom {
To {
Transform:scale (10)
}
}
Finally, add the discoloration effect:
@ keyframesrotating {
To {
Transform:rotate (180deg)
Filter:hue-rotate (1turn)
}
}
The great task has been completed!
