The method works... <http://www.tanfa.co.uk/archives/show.asp?var=300> ...it is only a question about how one applies it. > Understanding has layout is the main one.

The series of triggers for "Layout" in IE is non-standard... <http://www.satzansatz.de/cssd/onhavinglayout.html> ...but the effect is (for the most part) pretty similar to what we expect from more standard compliant browsers when we introduce "block formatting"... <http://www.w3.org/TR/CSS21/visuren.html#block-formatting> Both "Layout" and "block formatting" establish "a box with a calculated area which contains all "in-flow" content/elements and isolates all content/elements from what's outside this box's area." - Note that floats are "in-flow" elements, as they are interacting with all other "in-flow" elements. Thus "Layout" and "block formatting" contain floats. - Absolute and fixed positioned elements are take out of the flow - they do not interact with "in-flow" elements. Thus "Layout" and "block formatting" do not contain these positioned elements. - IE7 and older complicates positioning a bit since they can only absolute position an element out of a box/container if that box/container has "Layout". - "Layout" in itself is a bug the people behind IE made extensive use of to counteract other bugs in the Trident engine - a quick but problematic way to fix things. They are taking a somewhat more sound approach for IE8 - fixing and/or avoiding the actual bugs, so we can rely more on what's written in the standards when IE8 final arrives. > Over flow hidden used for clearing? Not for clearing, but for "block formatting". See above. > Also the use of zoom? In this context IE's proprietary "zoom" is just another trigger for "Layout" - a "hasLayout trigger" if you like. See "Thoughts on IE hack management"... <http://onhavinglayout.fwpf-webdesign.de/hack_management/> "Zoom" does of course have its own effects beyond that, as do all "Layout" and "block formatting" triggers. You must keep this "basic vs. additional effects" in mind when choosing clearing and containment methods, or else you may run out of options and not know how to solve design problems. > Forgive my questions, but as I stated it has been a while for me and > I feel like I have lost a lot of what I had within my brain over the > past year plus. You may as well take advantage of that "loss", and clear out any other misconceptions you may have collected over the years. Both standards and browsers' implementation of them have changed over the years, and old concepts tend to become less accurate and in many cases misleading over time because of this. It's a natural/logical process. A bit OT, but I tend to perform "clear, update, refine concepts" processes on my brain at irregular intervals - quite often really, to avoid being hampered by old information, observations and potential misconceptions. In a field as unfinished/unstable as web design, such frequent personal "unlearn, relearn, refine" processes are necessary if one wants to keep phase with progress and keep track of regress. "Old browsers (and their bugs) never die, they just fade away" - unfortunately :-) regards Georg -- http://www.gunlaug.no ______________________________________________________________________ css-discuss [cs...@lists.css-discuss.org] http://www.css-discuss.org/mailman/listinfo/css-d List wiki/FAQ -- http://css-discuss.incutio.com/ List policies -- http://css-discuss.org/policies.html Supported by evolt.org -- http://www.evolt.org/help_support_evolt/
