The above filter code mainly has three parameters, in order: startcolorstr, endcolorstr, and gradientType. Among them, gradientType=1 represents a horizontal gradient, and gradientType=0 represents a vertical gradient. startcolorstr="color" represents the starting color of the gradient, endcolorstr="color" represents the color at the end of the gradient.

The above code implements a gradient from red to blue, but does not include transparency changes. This is because IE currently does not support the opacity attribute and RGBA color. To achieve transparency changes under IE, you still need to use IE filters. Mirror, IE's transparency filter function is relatively powerful. This power is similar to the usage of css-gradient background gradient in Firefox or Safari browsers.

<html>
    <head>
    <style type="text/css">
        .gradient{
            width:300px;
            height:150px;
            background:-moz-linear-gradient(top, red, rgba(0, 0, 255, 0.5));  
        }
        </style>
