如何在PHP上使用点覆盖背景图像？ [关闭]

I want to make background image with the points on. Sorry I cannot explain it. I do not have enought reputation for the attaching image. Please visit: << hisset.in >> and watch to the background images

This is an HTML and CSS question.

Use two divs, one for the background and another for the dots layer.

.background {
  heigth: 100%;
  width: 100%;
  background: url('path/to/my/background.png');
}

.dots {
  heigth: 100%;
  width: 100%;
  background: url('path/to/my/dotslayer.png') repeat; //repeat the image all over the div
}

And use this image as 'dotslayer' (or another similar): http://www.hisset.in/images/dark/backgroundOverlay.png
