使用css3作为网站背景

Question

我想在不使用图像的情况下使用 CSS3 和 HTML5 texhnologies 获得这个结果。

这里是 HTML

<div id="overlay"></div>
<div id="lines"></div>

和 CSS

body {
    background: #45484d;
    z-index:-5;
}

#lines {
      background-size: 20px 20px;    
    background-image: -webkit-repeating-linear-gradient(0deg, #fff, #fff 2px, transparent 2px, transparent 7px),-webkit-repeating-linear-gradient(-90deg, #fff, #fff 2px, transparent 2px, transparent 7px);
    background-image: -moz-repeating-linear-gradient(0deg, #fff, #fff 2px, transparent 2px, transparent 7px),-moz-repeating-linear-gradient(-90deg, #fff, #fff 2px, transparent 2px, transparent 7px);
    background-image: -o-repeating-linear-gradient(0deg, #fff, #fff 2px, transparent 2px, transparent 7px),-o-repeating-linear-gradient(-90deg, #fff, #fff 2px, transparent 2px, transparent 7px);
    background-image:repeating-linear-gradient(0deg, #fff, #fff 2px, transparent 2px, transparent 7px),repeating-linear-gradient(-90deg, #fff, #fff 2px, transparent 2px, transparent 7px);
    height:100%;
    width:100%;
    opacity:0.14;
    position:absolute;
    top:0;
    left:0;
    z-index:-4;
}

#overlay {
    position:absolute;
    top:0;
    left:0;
    height:100%;
    width:100%;
    z-index:-3;
}

我在 jsfiddle 上得到了一些结果：

但不知道还能做什么。谁能帮我实现这个结果？

Answer 2

我对此的尝试（仅用于演示的 -webkit 规则（Chrome））：

background-size: 100px 100px;    

background-image:
   repeating-linear-gradient(0deg, #999, transparent 2px, transparent 20px),
   repeating-linear-gradient(0deg, #fff 1px, transparent 2px, transparent 100px),
   repeating-linear-gradient(90deg, #999, transparent 2px, transparent 20px),
   repeating-linear-gradient(90deg, #fff 1px, transparent 2px, transparent 100px);

(fiddle)

还有here 的加了条纹的：

background-size:4px 4px; 
background-image: 
  repeating-linear-gradient(45deg, transparent, transparent 1px, #333 2px, transparent 3px);
