How to make the picture darker with css

In css, we can use the filter attribute to make the picture darker, which is used to set The visual effect of the element. When the value of this attribute is brightness(), you can set the sensitivity of the image.

Apply a linear multiplication to the image, making it appear lighter or darker. If the value is 0%, the image will be completely black. If the value is 100%, there will be no change in the image. Other values correspond to linear multiplier effects. Values above 100% are okay and the image will be brighter than before. If no value is set, the default is 1.

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>
.img1 {
    filter: brightness(50%);
}
    </style>
  <img  class="img1 lazy"  src="/static/imghwm/default1.png"  data-src="1118.02.png"    alt="How to make pictures darker with css" >
