问题 I need help with trying to get this footer set in a fixed position. I'm learning as I go and trying to make a reasonably liquid layout. It's a work-in-progress but I can't continue until I get the footer in the right place. My problem is it keeps extending past the window to the right. Sometimes it creates a scrollbar and does not follow margin rules. I've tried just about everything I could think of and what I could find by using trusty google. I have used the latest chrome and firefox

问题 I want my top menu to be fixed and scroll with the page, but only when it get to the top of the screen. Like here: http://en.miui.com/forum.php anybody knows how? tnx :) 回答1: Either uses CSS' position:sticky with browser vendor prefixes or check the window's scrollTop when the element touches the top of the window and at the scrollTop or anything larger than it, fix the element with fixed positioning.
