scrollbar

问题 is it possible to use transitions on webkit scrollbars? I tried: div#main::-webkit-scrollbar-thumb { background: rgba(255,204,102,0.25); -webkit-transition: background 1s; transition: background 1s; } div#main:hover::-webkit-scrollbar-thumb { background: rgba(255,204,102,1); } but it isn't working. Or is it possible to create a similar effect (without javascript)? Here is a jsfiddle showing the rgba transition problem 回答1: It is fairly easy to achieve using Mari M's background-color: inherit;

问题 When I size my Chrome window to 328 x 455 pixels I still see a horizontal scrollbar. How can I find out which element is causing this? I've been looking elements via the developer console, but can't find the element. I then tried the script I found here, but nothing is logged.

问题 Is it possible to start a div's scrollbar from bottom (As initial position, not always) instead from top, with pure css? 回答1: Use transform:rotateX to wrap div and return it (to avoid the text from turning over) also in sub div .page{ overflow-y: scroll; width:150px; height:150px; transform:rotateX(180deg); -moz-transform:rotateX(180deg); /* Mozilla */ -webkit-transform:rotateX(180deg); /* Safari and Chrome */ -ms-transform:rotateX(180deg); /* IE 9+ */ -o-transform:rotateX(180deg); /* Opera *

问题 I am showing data from DB in an Activity. I want a Table and buttons on bottom. For data thought TableLayout would be best option for it. I added TableLayout to HorizontalView & to ScrollView making it scroll vertically & Horizontally. Am adding all rows dynamically - including header. This part is working fine. I want is when the contents is less than the screen width, it should yet occupy the whole screen width. For eg. If a table fits well in Portrait mode then ofcourse for Landscape mode

问题 Sometimes it happens that the scrollbar of my tree panel does not work anymore. While it's still possible to move the scrollbar, the tree doesn't move at all anymore. That happens to me in Firefox and in Chrome as well. Here is the source of my tree panel: var treeStore = Ext.create('Ext.data.TreeStore', { proxy: { type: 'ajax', url: '../tree.pl' } }); var tree = Ext.create('Ext.tree.Panel', { store: treeStore, renderTo: 'tree', title: 'Tree', width: 400, height: 450, rootVisible:false,

问题 I'm trying to make a custom widget, which is basically a bunch of textedits with a single vertical scroll bar on the right. To keep widget size determined, I have to find a width of the scrollbar, as texedits geometry depends on it. Simply calling scroll_bar->width(); for freshly created vertical bar returns 101, which is obviuosly wrong. So, is there a way to determine vertical scroll bar width correctly in Qt 3.2.3? 回答1: int w = qApp->style()->pixelMetric(QStyle::PM_ScrollBarExtent); 回答2: I

问题 The scroll bar is shown when user set "overflow:auto;" and the user can scroll things from top to bottom. The problem is , how can the javascript/jquery check when the scroll bar is either at the bottom or at the top? So that if (is_scrollbar_top || is_scrollbar_end) //do some thing.. So are there any funciton/ way to check such status? Thanks Updated: Not working- using jquery ui dialog html: <div class = "dialog" id="dialog" title="Past Issues"></div> javascript: $('#pastIssues').click
