how to make a css gradient stop after so many pixels?

Question

-moz-radial-gradient(center -200px , ellipse farthest-corner, #323C49 0%, #718299 65%) no-repeat scroll 0 0 transparent;

I have this code above and i just realized that this gradient goes from top to bottom. Is there any way to make it stop the whole gradient after 30px. I can make adjustments as necessary, but how do you get the gradients to complete itself after 30px?

Answer 1

You can use the background-size property together.

like this:

div {
    height: 100px;
    width: 100px;
    border: 1px solid black;

    background: radial-gradient(ellipse farthest-corner, #323C49 0%, #718299 65%) no-repeat;
    background-size: auto 30px;
    background-position: top;
}

<div></div>

Answer 2

In CSS3:

radial-gradient(ellipse at center center, 
  rgb(30, 87, 153) 0%, rgb(41, 137, 216) 100px, 
  rgba(255, 255, 255, 0) 101px, rgba(255, 255, 255, 0) 100%) 

You can have multiple stops in the gradient. You can also specify length in pixels rather than percentages. You can also use rgba to make transparent colours.

You start with your first colour at 0%, the center.
Then you have the second colour at x pixels (I'm using x=100 pixels here).
Then you go to transparent white at x+1 pixels.
And stay transparent all the way until 100%.

this should work in browsers that support CSS3.
