Fade image to transparent like a gradient

Tags:

gradient

I would like to have an image (a background image) to fade to transparent so that content behind it can actually be seen (barely, thanks to transparency).

I can achieve it obviously with a PNG image, but I need to ask to my graphic designer to change the image every time I want to change the start => stop transparency points (maybe I want more color or maybe I want less color and more transparency).

Are there any chance I can achieve the same effect with CSS3? I tried applying a gradient to transparent on a jpg (and a png) but I can't see through it unless the PNG has already transparency (and basically the gradient) already done (which makes the css gradient useless).

Any suggestion? I'm digging hard through the web but seems like I'm not using the right keyword or maybe it's not possible.

Update 1:

Code says more than a lot of words, I would like to do something like this (but the syntax is obviously wrong):

background: linear-gradient(to bottom, rgba(url('splash_bottom3.png'), 0.0), rgba(url('splash_bottom3.png'), 1.0));

How do you make a transparent gradient image in CSS?

To add transparency, we use the rgba() function to define the color stops. The last parameter in the rgba() function can be a value from 0 to 1, and it defines the transparency of the color: 0 indicates full transparency, 1 indicates full color (no transparency).

You can do this:
