问题 TL;DR: Is it possible to set the vanishing point ( perspective-origin ) for an element that is given perspective directly via transform: perspective() , as opposed to inheriting it from a parent via perspective: ? You can see an example at http://jsbin.com/fevik/2/edit. In the second set of elements, I would like each element to have its own vanishing point that I can specify. Discussion: It's easy to set the vanishing point ( perspective-origin ) for elements that are 3D-positioned by their

问题 Before you attempt to solve this please carefully read the constraints I'm dealing with. Constraints .pictureContainer needs to remain position: relative (because I have a hover menu that positions absolutely relative to it.) The image could be smaller than 80% of #slide in which case it still must align in the center. What this translates to? You can't simply do a margin: 0 10% because yes that would center this specific case, but it will not satisfy the case where the image is smaller than

问题 I have this position in this ways, the problem is translating each divs based on what i have. the css is like: .col-md-12 { display: flex; flex-wrap: wrap; } .col-md-12 input:checked + label { color: red; } .col-md-12 input:checked + label + div.slider { color: red; } .col-md-12 div.slide-1 { left: -100%; } .col-md-12 div.slide-2 { left: 0%; } .col-md-12 div.slide-3 { left: 100%; } .col-md-12 input { flex-basis: 3%; margin-right: 27%; order: 1; } .col-md-12 label { flex-basis: 30%; margin-top

问题 I have a little toggle sidebar that I am using jQuery UI. The problem is it is very jerky behavior. Anyway to may it look like a smooth scroll left/right? I am trying to get the outer shell to slide smoothly like the inner container slides. Currently it is snapping once the inner div is finished easing. $(".snapper").click(function() { $(".sidebar-wrapper").toggle("slide", { direction: "right" }, 1000); $("#sidebar").css("width" , "auto"); }); Online Example. http://frontendtrends.com/sidebar

问题 My issue is that I have a div (id=service-section-container) which contains 3 divs (class=service-section) which are shifted to the left of their parent div. I haven't found an efficient way to center the group of child divs using margins as using pixels would have a different result of different screens where as percentage didn't do the trick. It's probably a simple fix which I couldn't solve with my lack of experience, hence why I'd really appreciate your help. Example can be found at the
