User-Agent: Mozilla/5.0 (Windows; U; Win98; en-US; rv:1.5b) Gecko/20030906 Firebird/0.6.1+ Build Identifier: Mozilla/5.0 (Windows; U; Win98; en-US; rv:1.5b) Gecko/20030906 Firebird/0.6.1+ In standards-compliance mode, the BODY element does not obey the CSS rule { min-height: 100% } even though its parent (the HTML element) is the full height of the content-area. Reproducible: Always Steps to Reproduce: 1. Create a testcase which forces Gecko into standards-compliance mode. 2. Apply the CSS rule { min-height: 100% } to the BODY element. 3. Apply a border to the BODY element so you can see its dimensions. Actual Results: The BODY element is not as tall as the content-area. Expected Results: The BODY element should be at least as tall as the content-area.

Simplified testcase demonstrating the dimensions of the BODY element in standards-compliance mode. Opera displays it correctly, and MSIE does not because it doesn't support the 'min-height' property.

As I read the spec, what the testcase does looks like expected behavior. "The percentage is calculated with respect to the height of the generated box's containing block. If the height of the containing block is not specified explicitly (i.e., it depends on content height), the percentage value computes to '0' (for 'min-height') or 'none' (for 'max-height')." http://www.w3.org/TR/CSS21/visudet.html#propdef-min-height So since there is no explicit height for HTML (as confirmed by the DOM Inspector), min-height equals 0. I note also that if I add an explicit 100% height for HTML to your testcase, then it works as you expect. I think either Opera sets an explicit height in its UA CSS, or you have found an Opera bug since the testcase does behave as you expect in Opera 7. Resolving invalid on this basis.

Thanks for the clarification. I had assumed the HTML element has an explicit height of 100% because it always fills the content-area unless affected by explicit CSS rules, and it does not depend on content height.
