In HTML, you can use the filter attribute to brighten the picture. You only need to add the "filter:brightness(% value)" style to the picture element. The filter attribute sets the brightness() function to adjust the brightness of the image. When the value of this function exceeds "100%", it will make the image brighter.

In html, you can brighten images through the filter attribute. Let’s take an example to understand the implementation method:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<style>
.img1 {
-webkit-filter: brightness(50%);
/* Chrome, Safari, Opera */
filter: brightness(50%);
}
.img2 {
-webkit-filter: brightness(120%);
/* Chrome, Safari, Opera */
filter: brightness(120%);
}
</style>
</head>
<body>
<p>原图:</p>
<img src="img/1.jpg" alt="Pineapple" width="300">

<img class="img1" src="img/1.jpg" alt="Pineapple" width="300">
<img class="img2" src="img/1.jpg" alt="Pineapple" width="300">
</body>

Description:
The filter attribute defines the visual effect of the element (for example: blur and saturation).
Thebrightness(%) function adjusts the brightness of an image, applying a linear multiplication to the image to make it look brighter 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.
