问题 I've been trying to get a DIV to move up when using the scroll on browser to move down, but I can't find a solution which works.

问题 I see lots of answers for hiding the scrollbar by using overflow-y: scroll; and pushing the scrollbar away. But how would you achieve this for horizontal scrolling? 回答1: For webkit-based browsers (apple safari, google chrome, opera) you can get rid of scrollbar with simple CSS: .scrollable-container-class::-webkit-scrollbar { height: 0; width: 0; } It's easiest, but not cross browser way. Do not forget about (still lame) IE and Firefox. If you can live with empty padding at the top of your

问题 TL;DR : Applying visual effects to the contents of a ScrollView causes thousands of requests for the same (unchanging) image for each drag gesture. Can I reduce this? (In my real app, I have 50-odd images in the view, and the scrolling is correspondingly sluggish.) Gist To give a little life to a scrolling HStack of images, I applied a few transforms for a circular "carousel" effect. (Tips of the hat to sample code from John M. and Paul Hudson) The code is copy-paste-runnable as given. (You

问题 I have an app in wpf using caliburn micro framework with mvvm pattern which is running in kiosk with touch screen. i want to scroll buttons and when the user wants to click them. I have made grid scrollable inside a scroll viewer but the proplem is that when I leave the touch, it's raising the button-click event.

问题 I have a ListView with some Labels in it. The labels' width property is bound to the width property of the ListView but they seem to be slightly larger meaning that a horizontal scrollbar is shown on the list view. What I want is to fit the labels in the list view without the scrollbar on the bottom. I have looked at various padding and insets values on both the label and the list view but none I have found are the culprit (most are zero). Here is an example which demonstrates the problem.
