fixed

问题 I was working on my code when I stumbled upon this fun fact: z-index doesn't work for a fixed element and, therefore, fixed elements will always be in front. Is there a way to place a non-fixed element in front of a fixed element? Thanks. #fixed { background-color: red; width: 500px; height: 500px; position: fixed; z-index: 0; } #normal { background-color: blue; width: 500px; height: 500px; z-index: 1; } <div id = 'fixed'> I'm Fixed </div> <div id = 'normal'> I'm Normal </div> 回答1: Unless you

问题 I'm working on a site where I have to use a fixed DIV for the menu. www.atelier2architecten.nl/index2.php I'm trying to find a way to let the fixed div scroll horizontal. Because, when je make your browser window smaller you can't click the buttons that are outside te window. I found some jquery solution. But those include animation. My client doesn't want that. it has to stay fixed. I also found a great solution on this site But it doens't work when i use a DOC TYPE in my code. ( I need that

问题 I have coded a website in HTML and CSS. In this website I have used both properties margin: 0 auto and position:fixed on several occasions. The problem is that the website is correctly displayed in any modern browser except for IE 8+. Another problem that I found is that there should not be a space between the header and the browser window. Again this only happens with IE. This issues are usually related with the quirks mode of IE. However in this case I set the doctype correctly <!DOCTYPE

问题 i just cant make those left right fixed divs responsive. 3 divs : |fixed| |normal| |fixed| those 3 divs are in one div. if im going on full scale window they are working perfectly, but as i down size the window it's screws the all thing up. i dont know how to fix that- my center div working perfectly- responsive and centered. but the left and right fixed just wont be responsive as well. i guess the solution is connected to responsive width of the fixed divs.. any ideas? i added JSFIDDLE

问题 I have a strange behavior with my fixed top menu. The screen height is dynamic (depends on the number of registries retrived by the database). When the number of registries creates a scroll, but not high enough to cover up all the menu, the screen bounces and doesn't allow me to reach the bottom (the scroll jumps up again, no matter what). I was able to simulate the behavior here: http://jsfiddle.net/thiagoprzy/0kkx9tsb/ I believe the issue relies on the way I created the JS part, but when I

问题 I want to wrap my navigation and sub navigation in a div that becomes fixed once the user scrolls past the top. I'm using _s starter theme. My theme is called test. Here is my nav code along with the wrapper (I don't have the subnav in, since I'm trying to figure this out first): <div id='fixed-nav'> <nav id="site-navigation" class="main-navigation" role="navigation"> <h1 class="menu-toggle"><?php _e( 'Menu', 'test' ); ?></h1> <div class="skip-link"><a class="screen-reader-text" href="

问题 I'm trying to create a block which may or may not have a scrollbar, with a header that does not scroll. The trick is that the width of the header should be affected by the presence of a scrollbar. I'm worried that this is one of those CSS use cases which should be trivial, but might, in fact, be impossible. Anyone willing to prove me wrong? 回答1: Here are a few pointers http://davidchambersdesign.com/css-fixed-position-headers/ and there involve tables with fixed header and scrolling body http

问题 It's my understanding that a CSS fixed position element is relative to the viewport only. However, from what I can tell, this is true except that if "left" is unspecified, it doesn't default to 0 but rather to the left edge of what would have otherwise been its container - in this case, the main div. The HTML: <div id="main"> <div id="fixed"></div> <div id="content"></div> </div > The CSS: #main{ width:80%; margin-left:auto; margin-right:auto; } #fixed{ position:fixed; width:100%; height:25px
