How to use Layui to achieve image masking effect
In web development, the image masking effect is a common interactive effect, and images can be enhanced through masking The visual appeal can also play a certain prompting role. This article will introduce how to use the Layui framework to achieve image masking effects, and provide specific code examples.
Layui is a lightweight front-end UI framework that provides a wealth of components and interfaces and is very suitable for quickly building front-end interfaces. To achieve the image masking effect, you need to use some components and features of Layui, including image lists, masking layers, event listening, etc.
First, you need to download the Layui framework and introduce the relevant CSS and JavaScript files into the HTML file. You can download the latest version of the framework from the Layui official website (http://www.layui.com/), and then add the following code in the HTML file:
Next, you need to create a list to display the images. It can be implemented through Layui's table component, and combined with Layui's picture module, picture information can be displayed conveniently. Here is an example HTML code:
图片标题 | 图片 |
---|---|
图片1 | |
图片2 |
Note that only two images are shown in the above example, you can add more images as needed.
Next, you need to add some CSS styles to set the effect of the image mask. You can add the following code in thetag in the HTML file:
.layui-table td img { width: 100%; height: auto; cursor: pointer; position: relative; } .layui-table td .mask { position: absolute; top: 0; left: 0; width: 100%; height: 100%; background-color: rgba(0, 0, 0, 0.5); opacity: 0; transition: opacity 0.3s; } .layui-table td:hover .mask { opacity: 1; }
In the above code, we set the width and height of the image, as well as a pointer style. The mask layer uses absolute positioning and covers the top of the image, and the background color is translucent black. The transparency of the mask layer is set to 0, and a transition effect is added. When the mouse hovers over the image, the transparency of the mask layer changes from 0 to 1, realizing the animation of the mask effect.
Finally, you need to add some JavaScript code to monitor the click event of the image and display the effect of the large image. You can add the following code in thetag in the HTML file:
layui.use(['layer'], function() { var layer = layui.layer; $('.layui-table td img').click(function() { var src = $(this).attr('src'); layer.open({ type: 1, title: false, closeBtn: 0, skin: 'layui-layer-nobg', shadeClose: true, content: '', }); }); });
In the above code, we created a pop-up layer through Layui's layer module to display the large image . When the picture is clicked, the path of the picture is obtained, and a pop-up layer is opened through the layer.open method to display the large picture. The style and function of the pop-up layer can be adjusted according to your own needs.
So far, we have completed the steps of using Layui to achieve the image masking effect. You can carry out actual development based on the above sample code, and customize the style and functionality as needed. Through the components and features provided by Layui, it becomes simple and fast to achieve image masking effects.
