This article is about how to use pure CSS to achieve an animation effect without DOM elements. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.

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!
