When you apply a double border to a paragraph in a Word document and then you either
This behavior is caused by border width resolution limitations within all versions of Microsoft Internet Explorer.
In Word, when the width of a border is such that a line or gap would be less than 1 pixel wide, Word enforces a 1-pixel minimum width. This ensures that even a very thin double border is at least 3 pixels wide (line + gap + line). Therefore, the individual lines can be resolved. (One pixel is a measurement representing the smallest amount of information displayed graphically on the screen as a single dot.)
By contrast, Internet Explorer attempts to preserve total border width, rounded to the nearest pixel. This allows double borders to blend into a single border (at a width of less than 1.9 points) and single lines to disappear entirely (at a width of less than 0.38 point).
To summarize, on standard display devices with 96 dots per inch (dpi), double and single border styles are not displayed correctly (they're non-WYSIWEB) when the following are true:
To work around this problem, make double borders at least 3/4 point and single borders at least 1/2 point to be viewed correctly in Internet Explorer.
To change the border width:
Microsoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article.
