What is the overhead of C# fixed statement on a managed unsafe struct containing fixed arrays?
问题 I've been trying to determine what the true cost of using the fixed statement within C# for managed unsafe structs that contain fixed arrays. Please note I am not referring to unmanaged structs. Specifically, is there any reason to avoid the pattern shown by 'MultipleFixed' class below? Is the cost of simply fixing the data non zero, near zero (== cost similar to setting & clearing a single flag when entering/exiting the fixed scope), or is it significant enough to avoid when possible?
Fixed positioned div within a relative parent div
问题 I am currently building a responsive website and need a menu to be fixed, thus not scrolling when the rest of the site scrolls. the issue is that it is a fluid layout and i want the "fixed positioned" menu item to be fixed relative to the containing parent element and not to browser window. is there anyway this can be done? 回答1: This question came first on Google although an old one so I'm posting the working answer I found, which can be of use to someone else. This requires 3 divs including

Disable zoom on a div, but allow zoom on the page (an alternate div)
Is there a way to disable zoom on a div, or any particular elements on a website? For example, if I wanted the page to be zoomable, but not the #Header div, is there a way to make one zoomable, and the other not zoomable? Basically, when you zoom on a mobile device, it zooms the Header too, but I want the header to be a fixed size at all times (not zoomable). I know that you can use this code to disable zooming overall: <meta content='width=device-width; initial-scale=1.0; maximum-scale=1.0; user-scalable=0;' name='viewport' /> You can't do that without clever hacks. However, you can (and
How to fix a header on scroll
I am creating a header that once scrolled to a certain amount of pixels it fixes and stays in place. Can I do this using just css and html or do i need jquery too? I have created a demo so you can understand. Any help would be great! http://jsfiddle.net/gxRC9/4/ body{ margin:0px; padding:0px; } .clear{ clear:both; } .container{ height:2000px; } .cover-photo-container{ width:700px; height: 348px; margin-bottom: 20px; background-color:red; } .small-box{ width:163px; height:100px; border:1px solid blue; float:left; } .sticky-header{ width:700px; height:50px; background:orange; postion:fixed; }
C# Unsafe/Fixed Code
问题 Can someone give an example of a good time to actually use "unsafe" and "fixed" in C# code? I've played with it before, but never actually found a good use for it. Consider this code... fixed (byte* pSrc = src, pDst = dst) { //Code that copies the bytes in a loop } compared to simply using... Array.Copy(source, target, source.Length); The second is the code found in the .NET Framework, the first a part of the code copied from the Microsoft website, http://msdn.microsoft.com/en-us/library
How do I get a fixed position div to scroll horizontally with the content? Using jQuery
I have a div.scroll_fixed with the following CSS .scroll_fixed { position:absolute top:210px } .scroll_fixed.fixed { position:fixed; top:0; } I'm using the following jQuery code to set the .fixed class when the div reaches the top of the page. var top = $('.scroll_fixed').offset().top - parseFloat($('.scroll_fixed').css('margin-top').replace(/auto/, 0)); $(window).scroll(function (event) { // what the y position of the scroll is var y = $(this).scrollTop(); // whether that's below the form if (y >= top) { // if so, ad the fixed class $('.scroll_fixed').addClass('fixed'); } else { // otherwise
Fixed attachment background image flicker/disappear in chrome when coupled with a css transform
I am currently doing a parallax website theme. The background images need to be attached as fixed for certain 'div's and 'section's to avoid jquery indulging in everything. The problem was the background images of the tags below any animated item disappeared while the transformation is being done, only on Google Chrome. Remedy? This has been a very common unsolved mystery. Recently I had the same problem, and '-webkit-backface-visibility: hidden', proved to be less than useless (on my 'fixed' attached background), since the background just disappeared when it was set.
