How to use CSS3 and JavaScript to achieve the effect of scattering and enlarging the surrounding pictures after clicking?

Create cool web interaction: click on the picture, and the surrounding pictures spread and enlarge!
Many websites use this compelling interaction: click on an image and it will enlarge, while the surrounding images will spread out. This article will explain in detail how to achieve this effect using CSS3 and JavaScript.
First, we need to add a click event listener to each image. When a user clicks on an image, the JavaScript code executes, resizing the position and size of all images. The key is to use the transform attribute of CSS3 to achieve the displacement and scaling of the picture.
The steps are as follows:
1. HTML structure: for each <img src="/static/imghw/default1.png" data-src="https://img.php.cn/upload/article/001/246/273/174312337946553.jpg" class="lazy" alt="How to use CSS3 and JavaScript to achieve the effect of scattering and enlarging the surrounding pictures after clicking? "> <img src="/static/imghw/default1.png" data-src="https://img.php.cn/upload/article/001/246/273/174312337917621.jpg" class="lazy" alt="How to use CSS3 and JavaScript to achieve the effect of scattering and enlarging the surrounding pictures after clicking? "> <img src="/static/imghw/default1.png" data-src="https://img.php.cn/upload/article/001/246/273/174312338030325.jpg" class="lazy" alt="How to use CSS3 and JavaScript to achieve the effect of scattering and enlarging the surrounding pictures after clicking? "> 2. JavaScript code: The spread() function receives the clicked image element as a parameter and calculates the displacement and scaling ratio of other images:
function spread(img) {
const images = document.getElementsByTagName('img');
const index = Array.prototype.indexOf.call(images, img);
for (let i = 0; i <p> In this code, <code>Math.sin</code> and <code>Math.cos</code> functions calculate the image displacement, <code>100</code> controls the scattering radius, and <code>scale</code> controls the scaling ratio. The clicked image has a scale of 2, and the other images remain as they are.</p><p> <strong>3. CSS style:</strong> Set the initial position, size and transition effect of the picture:</p><pre class="brush:php;toolbar:false"> img {
position: absolute;
left: 50%;
top: 50%;
transform: translate(-50%, -50%) scale(1);
transition: transform 0.5s ease-in-out;
/* Add other styles, such as image size*/
width: 100px;
height: 100px;
} position: absolute enables the image to be absolutely positioned, translate(-50%, -50%) centers the image, and the transition attribute allows the image transformation process to smoothly transition.
Through the above steps, you can achieve the effect of scattering the surrounding pictures and enlarging them by themselves after clicking on them. You can fine-tune the effects by adjusting parameters in your code (such as spreading radius, scaling, transition time) and add more animation or interaction details to enhance the user experience. Remember to replace "image1.jpg" , "image2.jpg" and "image3.jpg" as your actual image path.

What is 'render-blocking CSS'?
Jun 24, 2025 am 12:42 AM
CSS blocks page rendering because browsers view inline and external CSS as key resources by default, especially with imported stylesheets, header large amounts of inline CSS, and unoptimized media query styles. 1. Extract critical CSS and embed it into HTML; 2. Delay loading non-critical CSS through JavaScript; 3. Use media attributes to optimize loading such as print styles; 4. Compress and merge CSS to reduce requests. It is recommended to use tools to extract key CSS, combine rel="preload" asynchronous loading, and use media delayed loading reasonably to avoid excessive splitting and complex script control.

Choosing the correct display value in CSS is crucial because it controls the behavior of elements in the layout. 1.inline: Make elements flow like text, without occupying a single line, and cannot directly set width and height, suitable for elements in text, such as; 2.block: Make elements exclusively occupy one line and occupy all width, can set width and height and inner and outer margins, suitable for structured elements, such as; 3.inline-block: has both block characteristics and inline layout, can set size but still display in the same line, suitable for horizontal layouts that require consistent spacing; 4.flex: Modern layout mode, suitable for containers, easy to achieve alignment and distribution through justify-content, align-items and other attributes, yes
