Rotate the Divs

In this step, you will learn how to rotate the 12 div elements on the page to create the fan-like effect.

  1. Open the style.css file in your editor.
  2. Add the following CSS rules to the file:
#box:hover div:nth-child(6) {
  transform: rotate(-10deg);
}

#box:hover div:nth-child(5) {
  transform: rotate(-20deg);
}

#box:hover div:nth-child(4) {
  transform: rotate(-30deg);
}

#box:hover div:nth-child(3) {
  transform: rotate(-40deg);
}

#box:hover div:nth-child(2) {
  transform: rotate(-50deg);
}

#box:hover div:nth-child(1) {
  transform: rotate(-60deg);
}

#box:hover div:nth-child(7) {
  transform: rotate(10deg);
}

#box:hover div:nth-child(8) {
  transform: rotate(20deg);
}

#box:hover div:nth-child(9) {
  transform: rotate(30deg);
}

#box:hover div:nth-child(10) {
  transform: rotate(40deg);
}

#box:hover div:nth-child(11) {
  transform: rotate(50deg);
}

#box:hover div:nth-child(12) {
  transform: rotate(60deg);
}

These rules rotate the first 6 div elements (id="item1"~id="item6") counterclockwise with a minimum rotation angle of 10 degrees and a difference of 10 degrees between adjacent elements. The next 6 div elements (id="item7"~id="item12") are rotated clockwise with a minimum rotation of 10 degrees and a difference of 10 degrees between adjacent elements.

  1. Save the style.css file.
  2. Go back to the browser and refresh the page. You should now see the fan-like effect when you hover over the element.
