Methods and techniques on how to achieve rotation and translation effects of images through pure CSS

In modern web design, animation effects have become a way to attract user attention and enhance users An important part of the experience. The rotation and translation effect of pictures is one of the more common animation effects. In this article, I will explain how to achieve this effect through pure CSS and provide specific code examples. Let’s learn together!

First, we need an HTML container to place our images. The following is a basic HTML structure:

<div class="image-container">
  <img src="/static/imghw/default1.png"  data-src="image.jpg"  class="lazy" alt="Image">
</div>

Next, we need to set some styles for this container. We will use the CSS transform property to achieve rotation and translation effects. The following is a basic CSS style:

.image-container {
  position: relative;
  width: 200px;
  height: 200px;
  overflow: hidden;
}

.image-container img {
  position: absolute;
  top: 50%;
  left: 50%;
  transform: translate(-50%, -50%);
  transition: transform 0.5s ease;
}

In the above code, we set up a parent container image-container to contain our image and set some basic styles. We then center the image using absolute positioning and translate it to the center of the container using the transform property of CSS.

Now, we can start to implement rotation and translation effects. The following is a basic CSS style to rotate the image when the mouse is hovered:

.image-container img:hover {
  transform: translate(-50%, -50%) rotate(45deg);
}

In the above code, we use the CSS :hover pseudo-class to indicate when the mouse is hovering The state when stopped on the picture. Then, we change the transform property to rotate the image 45 degrees.

Next, we can add a translation effect. Here is a basic CSS style to simultaneously rotate and translate an image on mouseover:

.image-container img:hover {
  transform: translate(-50%, -50%) rotate(45deg) translateX(-50px) translateY(50px);
}

In the above code, in addition to rotation, we also use translateX and translateY attributes to achieve horizontal and vertical translation effects. This way, when the mouse is hovering over the image, the image will be rotated at a 45-degree angle and translated -50 pixels along the X-axis and 50 pixels along the Y-axis.

In addition to the above basic examples, by combining rotation, translation and other CSS properties, we can also achieve more complex effects, such as scaling, transparency changes, etc. As long as we use CSS flexibly, we can achieve various cool animation effects.

I hope the above example can help you understand how to achieve the rotation and translation effect of images through pure CSS, and provide some inspiration for your web design. Remember, when applying these effects, you should also consider compatibility and performance issues to ensure good display on a variety of devices and browsers.
