scrollbar

问题 I created canvas inside the div tag and add background image to the canvas. Here is the code: <div id="container" style="width: 740px; height: 420px"> <canvas id="canvas_draw"></canvas> </div> #container { position: relative; } #canvas_draw { border: 1px dashed #CCCCCC; margin: 5px; border-style: dotted; border-width: 1px; background-color: #FFFFFF; overflow:scroll !important; background-image:url('Images/sample.jpg'); background-repeat: no-repeat; background-size: 900px 600px; vertical-align

问题 Now use this code (and many variations of this), but scroll track get dark-grey color, something like #222222 or near this. Find many examples, but all of them give same result. Opera, Chrome and Firefox show this bug. How to fix? #style-3::-webkit-scrollbar-track { -webkit-box-shadow: inset 0 0 6px rgba(0, 0, 0, 0.3); background-color: transparent; } #style-3::-webkit-scrollbar { width: 6px; background-color: transparent; } #style-3::-webkit-scrollbar-thumb { background-color: #000000; } 回答1

问题 I have an iframe on www.example.com that points to support.example.com (which is a CNAME to a foreign domain).

On Firefox and IE this works great, there is no scrollbar since I use <iframe ... scrolling="no"></iframe> . However, on webkit browsers (Safari and Chrome), the vertical scrollbar persists even when there is sufficient room for the page without the

问题 I'm trying to create custom events in JQuery that are supposed to detect when a scrollbar is clicked 1 . I know there's lots of text, but all my questions are boldfaced and there's a JSFiddle example you can work on straight away. Because I haven't found any built in functionality for this, I had to create a hasScroll function, checking if the element has a scrollbar, $.fn.hasScroll = function(axis){ var overflow = this.css("overflow"), overflowAxis; if(typeof axis == "undefined" || axis ==

问题 I'm pretty new to Python and have delopped a little program. In that program the user is able to open a Toplevel window as a popup which shows a map as an image file. I've managed to add a scrollbar to it and make the image scrollable. The reason for the scrollbar is to support different screen resolutions so that if the shown image is too big, the user can scroll the content of the popup. I now would like to ensure that the scrollbar changes size, when the popup window changes size or isn't

问题 I am trying to synchronise scrolls across the tableviews. (Both Horizontal & Vertical) The SyncScrollEx View has two tableView which is basically one Fragment placed side by side, with same dataset, and hence same table size layout.
