A little white space appears above the top end of the left and right borders, creating an unexpected two-coloured border.
Reproducible: Always
Steps to Reproduce:
1. Attach the following CSS:
html, body
{
width: 100%;
height: 100%;
margin: 0px;
padding: 0px;
}
#layout
{
width: 1000px;
border-left: 12px solid red;
border-right: 12px solid red;
margin-left: auto;
margin-right: auto;
}
2. Create an HTML file with a XHTML 1.0 Transitional DOCTYPE, and insert this into the <BODY> tag:
<div id="layout">
<img src="myimage.png" width="1000" alt="" />
</div>
Actual Results:
Border has 8px or so of white color, and the rest in red.
Expected Results:
All the border line should be red.
Can you create a HTML testcase and attach it to this bug or provide a URL which exposes this problem?

Can't reproduce the bug with attatchment 457751. Is this problem new?
Note that
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
triggers "Almost Standards Mode" if served as text/html.
With a "Standards Mode" doctype like
<!DOCTYPE html>
I see a white space at the *bottom* end of the red borders.
This white space is just the lower baseline of the div's inline content.
Setting |display:block| to the image would fix that.

But why a white space and not just *blank space*?

As said in comment 3, can't reproduce with attachment 457751 [details].
Chancing to Standards Mode triggering <!DOCTYPE html>, I see a blank space as expected. This space has body's background-color, also as expected.
-> WFM. Reporter, if you see anything different, please explain and reopen.
