Methods and techniques on how to achieve the zoom and rotation effect of images through pure CSS

CSS is a style language commonly used in front-end development, which can be used to define web pages layout, colors, fonts and other styles. In addition to these basic functions, CSS can also achieve some amazing effects, such as zooming and rotating images.

This article will introduce how to achieve the zoom and rotation effect of images through pure CSS, and provide specific code examples.

First, we need to prepare a picture. Let's say we have an image called "image.jpg" and we will manipulate it via CSS.

1. Zoom effect
   To achieve the zoom effect of the image, we can use the CSS transform attribute. This attribute can scale the element through the scale() function.

For example, to enlarge the image to 2 times its original size, we can use the following code:

.image {
  transform: scale(2);
}

If you want to reduce the image, you can set the parameters of the scale() function to less than 1 value.

2. Rotation effect
   To achieve the rotation effect of the image, you can also use the CSS transform attribute. The difference is that we need to use the rotate() function to rotate the element.

For example, to rotate the image 45 degrees clockwise, we can use the following code:

.image {
  transform: rotate(45deg);
}

It should be noted that the parameter of the rotate() function is the angle, and you can set the positive Negative values ​​control the direction of rotation.

3. Scale and rotate at the same time
   If you want to achieve the effect of simultaneous scaling and rotation, you can use the scale() function and rotate() function in combination.

For example, to enlarge the image to 2 times its original size and rotate it 45 degrees clockwise, we can use the following code:

.image {
  transform: scale(2) rotate(45deg);
}

By adjusting the scale() function and rotate( ) function parameters, we can easily achieve different scaling and rotation effects.

4. Transition Effect
   In addition to the basic scaling and rotation effects, we can also add transition effects to the image to make it scale or rotate smoothly.

To achieve a transition effect, we can use the CSS transition attribute. This attribute can define the transition effect of the element, including transition attributes, transition time and transition function.

For example, to add a transition effect to the scaling and rotation of an image, you can use the following code:

.image {
  transition: transform 0.3s ease-in-out;
}

.image:hover {
  transform: scale(1.5) rotate(180deg);
}

In the above code, we added a :hover pseudo-class to the original image style , indicating that when the mouse hovers over the image, the transition effect is triggered. By adjusting the parameters of the transition time and transition function, we can customize the speed and manner of the transition effect.

Through the above methods and techniques, we can easily achieve the zoom and rotation effect of images. Whether used to display product images, create animation effects, or improve the visual appeal of web pages, these effects can bring a better user experience to the web page.
