In this post, we're going to take a look at how to make an image fade to transparent, or what I like to call transparent image gradient with CSS.

This is the example.

Notice how the bottom part of the image is slowly fading into the background, making it much easier to read the text on top of it.

To achieve this effect, we'll need to use CSS masking, the mask-image property.

Basically, we're creating a mask layer on top of an image to partially or fully hide portions of the image.

Note: As of the time of writing this article (September 2022), most browsers only have partial support for CSS masking. So we need to add the -webkit- prefix in addition to the standard property in most browsers.

Without further ado, here is the CSS that you need to apply to the image:

.transparent-gradient {
  -webkit-mask-image: linear-gradient(180deg, rgba(0, 0, 0, 1), rgba(0, 0, 0, 0));
  mask-image: linear-gradient(180deg, rgba(0, 0, 0, 1), rgba(0, 0, 0, 0))
}

You can also fine-tune the gradient direction by changing the first argument, and also the degree of transparency with the second and third arguments, more specifically, the a part of rgba, which stands for alpha (transparency).

That's it. Hope you find it useful.
