How about this css?
This source allows us to make 1px border if using any browsers.
We can call css at (X)HTML.
hr {
color:#E0F4D5;
border: 0;
height: 1px;
background-color:#E0f4D5;
}
This code can be used from firefox, IE5.0~, Opera to Safari.
The border size is flexible if you want.
If you want some class or ID, you can classify some class.
For example
div#left hr {
color:#fff;
border: 0;
height: 1px;
background-color:#fff;
}
div#center hr {
color:#000;
border: 0;
height: 3px;
background-color:#000;
}
But, I’m sorry for missing your point.
