Dynamic HTML: The Definitive Reference

Name

BORDER — NN n/a IE 4 HTML n/a

Synopsis

BORDER=”pixelCount"

Optional

Theory and practice of IFRAME element borders in Internet Explorer 4 diverge a lot, especially when trying to match behaviors across operating systems. IE 4 for the Macintosh displays IFRAME elements with a 3-D effect around the border that is always visible, no matter what border attribute settings are assigned. For the Windows 95 version, the 3-D effect goes away when you turn off the FRAMEBORDER attribute. As for the BORDER attribute, the size of the border acts as a margin setting in IE 4/Mac, but only for the top and left edges of the frame space: content is displaced to the right and down by the border size, causing the content to flow over the right and bottom edges—quite a mess. The BORDER attribute setting appears to have no effect in Windows 95. In no case does the border around an IFRAME look like a FRAME element border in IE 4.

That the HTML 4.0 specification does not include a BORDER attribute might lead one to believe it prefers the use of style sheet borders, instead of borders tied only to frames. If you want a genuine border around an IFRAME element in IE 4, use a style sheet border instead. Its behavior is far more consistent and predictable (and is thoroughly unrelated to nonfunctioning style sheet borders for frames defined by a FRAMESET).
