Safari Conditional CSS

How can I add css to be only read by safari? bascially a div needs moving 5pixels to the left, as it shows fine on ff/ie etc

Thanks

EDIT - added code

code:

#subheading
{
background-c开发者_如何学编程olor: #004376;
color: #ffffff;
height: 25px;
padding: 10px;
margin: 0 933px;
margin-top: -25px;
width: 761px;   
}

you can have a check for a specific css property in webkit. This would likely work in chrome as well.

@media screen and (-webkit-min-device-pixel-ratio:0) {
        .someClass{
            color:#FF0000;
        }
    }

margin: 0 933px;
margin-top: -25px;
width: 761px;

This doesn't sound right. The first line sets both left and right margin to 933px. And the width is 761px. The total width of the element would be (933 * 2 + 10 * 2 + 761) = 2647px.

Is this what you want it to be?
