Methods and techniques on how to achieve the blurred magnification effect of images through pure CSS

Abstract: Implementing the blurred magnification effect of images through pure CSS can make the web page more attractive Powerful visual effects. This article will introduce a simple method and some techniques, including specific code examples.

1. Background knowledge
Before introducing the implementation method, let us first understand some background knowledge. There is a filter attribute in CSS that can apply various graphical effects to elements, including a blur effect. By applying filter properties to image elements, we can achieve a blur effect on the image. In addition, there is a transform attribute in CSS that can perform operations such as rotating, scaling, and tilting elements. By combining filters and transformation properties, we can achieve a blurred magnification effect on images.

2. Methods and Techniques
Below we will introduce a simple method and some techniques to achieve the blurred magnification effect of pictures.

1. Create HTML structure
   First, we need to create an HTML structure containing images. You can use the img tag to insert an image into a document, and add a unique ID to the img tag so that you can later reference the image in CSS.

Sample code:

2. Add styles
   Next, we need to add CSS styles to the images. We can select image elements through CSS selectors and add filters and transformation attributes to them.

Sample code:

#my-image {
  filter: blur(5px);
  transition: all 0.3s ease;
}

#my-image:hover {
  transform: scale(1.2);
  filter: blur(0);
}

In the above sample code, we added filter and transition attributes to the ID of the picture element. In the initial state, a blur filter is applied to the image, giving it a blurry effect. When the mouse is hovering over the image, the image is enlarged through the transform attribute (zoom factor is 1.2) and the filter effect is removed. By adding transition attributes to elements, you can achieve smooth transition effects.

3. Compatibility considerations
   When using CSS filters and transformation properties, you need to pay attention to the compatibility of different browsers. Currently, most modern browsers support these attributes, but there are still some older browsers that do not or have limited support. In order to ensure that the effect can be displayed normally in different browsers, you can use CSS prefixes and tools such as Modernizr for compatibility processing.

3. Summary
Through the above simple methods and techniques, we can easily achieve the blurred magnification effect of images. Through the combined application of CSS filters and transform properties, we can add more attractive visual effects to web pages. It should be noted that compatibility is an important issue to consider when using CSS features, and corresponding processing needs to be done in the code to ensure that the effect can be displayed normally in mainstream browsers.
