How to achieve image edge blur effect in css
We can achieve image edge blur effect through box-Shadow attribute.
The syntax of this attribute is as follows:
box-shadow: h-shadow v-shadow blur spread color inset;
Among them, the box-Shadow attribute adds one or more drop-down shadows to the box. This property is a comma-separated list of shades, each shade specified by 2-4 length values, an optional color value, and an optional inset keyword. The value for omitted length is 0.
Let’s take a look at it through an example. The example is as follows:
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <meta http-equiv="X-UA-Compatible" content="ie=edge"> <title>Document</title> </head> <body> <style> .img-edge-cover { width: 180px; height: 180px; position: relative; } .img-edge-cover:after { position: absolute; content: ''; width: 100%; height: 100%; top: 0; left: 0; box-shadow:0 0 50px 30px #ffffff inset; } .img-edge-cover img{ width: 180px; height: 180px; display: block; margin-bottom: 20px; } </style> <div class="img-edge-cover"> <img src="1118.02.png" alt="photo"> </div> </body> </html>
