overflow

问题 I'm trying to iterate depth-first over a tree structure in Rust. I thought I had a really nice concise solution for this, but I can't get it to compile. Conceptually it's pretty simple: iterate over the children, get each child's depth first iterator, flatten them, and chain the current node's metadata iterator to it. #[derive(Debug, Eq, PartialEq)] struct Node { metadata: Vec<i64>, children: Vec<Box<Node>>, } impl Node { fn depth_first_metadata_iter(&self) -> impl Iterator<Item = &i64> + '_

问题 I have a container with some text and an image, and a navigation div that should (when the time comes) slide in from the right. To make this happen, I though I'd push the div to the right of the screen and put overflow-x: hidden on it's container to hide it, and then push it back into the screen when it's needed. The problem is , when I set overflow-x: hidden on the container, it also clips off the vertical content of the navigation. Here's a fiddle with a demo. What I have tried: Setting

问题 You can see the problem I'm having here : https://jsfiddle.net/xa6b8qmm/ I'm using overflow: hidden because I want to hide the scrollbar However, this hides the left & right shadow of the elements. I can't find a way to hide the scrollbar while at the same time allow for left/right sides of the box-shadow property to be visible. Any ideas ? CSS : .noscrollbar { position: relative; float: left; height: 300px; width: 500px; overflow: hidden; } .scroller { position: relative; float: left; height

问题 I'm looking for a way to add "... read more" hyperlink to end of visible part of multi-line text if its height exceeds 8em.

How to make it to appear and allow user to click in it ? something like: asd sadas sads asda dfdsf dfds sdf ... read more jquery and ASP.NET MVC2 are used. .description { max-height: 8em; overflow: hidden; font-size: small; text-overflow: "<a href='details'>... read more</a

问题 If I have a VB.Net function that returns an Int32, but uses an unsigned int (UInt32) for calculations, etc. How can I convert a variable "MyUintVar32" with a value of say "3392918397 into a standard Int32 in VB.Net? In c# if I just do a "return (int)(MyUintVar32);", I get -902048899, not an error. I've tried several different methods. What is the difference in the way c# handles these conversions versus VB.Net? 回答1: I realize this is an old post, but the question has not been answered. Other

问题 Currently I am designing a website using CSS and HTML etc. But I have faced a problem there : my child div goes outside the parent div when I add floating to the child. The site resides here my web design 回答1: Be more specific. Where is the problem on the website? Try to add this to css, so parent will know about the size of the child element: #parent{ overflow:hidden; } 回答2: You need to clear after your float. Try adding this css: CSS .container:after { content: ""; display: table; clear:

问题 What am I expecting is a page that is not overflowing since there is no content and hence have no need to scroll. But what I am getting is a page that is empty but it still scrolls, and isn't just a cosmetic issue of the scroll bars appearing on the touch event. It actually offsets the background in the view port. I've been trying everything that Google has thrown at me to make sure the width and height of the body block is the size of the viewport and no greater. I've also tried over-flow:
