How to use CSS to achieve image rotation effects

CSS (Cascading Style Sheets) is a markup language used to set the style and layout of web pages. Through CSS, we can achieve many attractive web page effects, including image rotation effects. In this article, we’ll discuss how to use CSS to rotate images and provide some concrete code examples.

In CSS, we can use thetransformattribute to achieve the rotation effect of the image.transformAttributes can apply various transformation functions, including rotation, scaling, translation, etc. The following is a simple HTML structure, containing an image and a button:

       
  
  旋转 
   

In the above example, we first define a container with the class name.image-container, using to wrap the image and spin button. The container uses theposition: relativeattribute to enable subsequent absolutely positioned buttons to be positioned relative to the container. In the container, we placed a picture and a button. The picture uses the.imageclass name for style setting, and the button uses the.rotate-btnclass name for style setting.

It is worth noting that the image uses theobject-fit: coverattribute to maintain the proportion of the image in the container and fill the entire container.

In the button click event handling functionrotateImage(), we use JavaScript to select the image element and rotate the image through thestyle.transformattribute . In this example, we setrotate(45deg)to rotate the image 45 degrees clockwise.

In addition to JavaScript, we can also achieve image rotation effects through CSS animation. Here is an example of using CSS animation:

In the above example, we used@keyframesto define an animation namedrotateAnimation. The animation gradually rotates the image 360 degrees from 0% to 100%. Next, we applied this animation to the picture element.image, and set the animation execution time to 5 seconds, the number of loops to unlimited, and the animation speed to linear.

Through the introduction of the above example, we can see that through thetransformproperty and animation properties of CSS, we can easily achieve the rotation effect of the image. Of course, there are many other transformation functions and animation features that allow us to create even more cool effects. I hope the introduction in this article can help you better use CSS to achieve web page effects.
