How to brighten images with css
You can brighten images through the filter attribute. The filter attribute defines the element (usually ) visual effects (such as blur and saturation).
When the attribute value is brightness, apply 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.
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(200%); } </style> <img src="1118.02.png" class="img1" alt="How to make pictures brighter with css" > <img src="1118.02.png" class="img2" alt="How to make pictures brighter with css" > </body> </html>
