问题 I've been building a site and I get a horizontal scrollbars and huge space to the right of the product pages. My first thought was an unclosed div, but I have validated with W3C and it checks out. I wonder if it's because of something (the buttons,tabs) that is relatively positioned. Would you please point me in the right direction. Any help is much appreciated.

阅读更多关于 JQuery offset returns elements “old” position in IE7

问题 Ok, got a weird bug going on here and so far google has failed to turn up anything addressing it. When using IE7 (actually IE8 compatibility) the JQuery offset function is not returning the current offset of an element.

问题 I'm trying to build a website template where the main #content div is 75% the width of the screen, and centered on the page, but I also want to occasionally have sections that span the full width of the viewport. The way I've accomplished this is by applying a class of .full-width on these sections that overrides the margins of the #content div by setting the width to 100vw, as well as some other properties that you can see in the CSS below. The problem is that, when enough content is on the

阅读更多关于 Position Fixed Broken in Chrome with Flash behind

问题 I have a strange bug that recently started happening in Chrome (works fine in IE, FF and even Safari). This was working a few weeks ago, so I am assuming this is a bug that came about in a recent Chrome build. Basically I have flash fixed "behind" the page, and I have an overlay fixed above the page (controls for video).

How to position a html element under a fixed div

问题 I am trying to position some html elements (particularly h1 and p) under a position: fixed div without having to use the <br> element, because if the top div gets resized (in height), then it will overlap the <h1> and <p> element.
