CSS3中的linear-gradient(…)不能按规范工作?

[英]linear-gradient(…) in CSS3 not working according to specifications?

Here's the current version of my webpage: 这是我网页的当前版本:

<html>
<head>
    <title>my site</title>


    <style type="text/css">
        #mtx_bckgd
        {
            font-family: Courier New;
            height: 1000px;
            width: 1000px;
            position: absolute;
            z-index: -1;
        }
        #mtx_bckgd > p
        {
            word-wrap: break-word;
            color: #D8D8D8;     
            overflow: hidden;
        }
        #header
        {
            position: absolute;
            font-family: Trebuchet MS;
            width: 1000px;
            height: 70px;
            text-align: center;
            border: solid 2px #424242;
            top: 25px;
            font-size: 20;
        }
    </style>
    <script type="text/javascript">
        function change_bckgd()
        {
            var bitstr = "";
            for (var i = 0; i < 4000; ++i)
                bitstr += Math.floor(Math.random()*10) % 2 ? "0" : "1";
            document.getElementById("mtx_txt").innerHTML = bitstr;

        }
    </script>


</head>
<body>
    <div id="mtx_bckgd">
        <p id="mtx_txt"></p>
    </div>
    <div id="header">
        <h1>JaminWEB</h1>
    </div>
    <script type="text/javascript">
        setInterval(change_bckgd, 200);
    </script>
</body>
</html>

What I plan on doing is creating a vertical fade across the background, from white at the bottom to light grey (the same grey I used for the 0's and 1's in the background) at the top. 我打算做的是在背景上创建垂直的淡入淡出,从底部的白色到顶部的浅灰色(与我在背景中用于0和1的灰色相同)。

According to W3schools ( http://www.w3schools.com/css/css3_gradients.asp ), the syntax 根据W3schools( http://www.w3schools.com/css/css3_gradients.asp ),语法

background: linear-gradient(angle, color-stop1, color-stop2);

means I should add the line 表示我应该添加行

background: linear-gradient(90, white, #D8D8D8)

in the #mtx_bckgd block in the stylesheet. 在样式表的#mtx_bckgd块中。 But when I do that, I'm getting a dark blue fade and my 0's and 1's are turning white. 但是,当我这样做时,我会得到深蓝色的淡入淡出,并且我的0和1变成白色。

The problem is the "90" in background: linear-gradient(90, white, #D8D8D8) is incorrect. 问题是background: linear-gradient(90, white, #D8D8D8)的“ 90” background: linear-gradient(90, white, #D8D8D8)不正确。 According to W3Schools it should be: 根据W3Schools,它应该是:

background: linear-gradient(90deg, white, #D8D8D8)

or 要么

background: linear-gradient(to right, white, #D8D8D8);
