How to apply multiple css radial gradients to a si

问题:

I have the following style applied to my div element:

background-image: -moz-radial-gradient(50% -10%, ellipse closest-corner, rgba(5, 5, 5, 0.7), rgba(0, 0, 0, 0) 100%);

This has the desired effect (being an inner drop shadow only at the top of the div). I would like to apply the same effect at the bottom of the div. The following line does it well, but it seems to override the first, so I can only get one or the other.

background-image: -moz-radial-gradient(50% 110%, ellipse closest-corner, rgba(5, 5, 5, 0.7), rgba(0, 0, 0, 0) 100%);

Can someone show me how I can have multiple radial gradient backgrounds per element? I notice that webkit can do this easily, but I'm looking for a cross browser implementation/alternative.

Thanks

回答1:

Just sepereate each one with a comma.

Something like this :

background-image: url(),url(), url();

Ofcourse instead of url you can put gradient.

And all modern browsers support this feature ( meaning IE does not).

In order to make it available in IE, you can use pie.htc

You just list them one after the other - like this:

background: radial-gradient(top left, 
            rgb(205, 230, 235) 34%, 
            transparent 34%), 
        radial-gradient(center, 
            rgb(205, 230, 235) 34%, 
            transparent 34%);

The best way to do that is to list them in the background property. But keep in mind that the order of properties is extremely important.

background:
    radial-gradient(circle at top left, transparent 15px, #58a 0) top left,
    radial-gradient(circle at top right, transparent 15px, #58a 0) top right,
    radial-gradient(circle at bottom right, transparent 15px, #58a 0) bottom right,
    radial-gradient(circle at bottom left, transparent 15px, #58a 0) bottom left;
background-size: 50% 50%;
background-repeat: no-repeat;

background then -size and -repeat, otherwise it won't work. It took me something like 30 mins to get it. Hope it will be helpful for someone.

You have to set the value of the radial gradient to transparent in order to let the other background come through:

   background-image: radial-gradient(closest-corner at 40% 70%,#FFFFFF 0%, rgb(171,171,171),50%,transparent),
                     radial-gradient(closest-corner circle at 80% 20%, #FFFFFF 0%, rgb(171,171,171),20%,transparent),
                     radial-gradient(closest-corner circle at 10% 10%, #FFFFFF 0%,rgb(171,171,171) 25%);
