scrollbar

问题 I wanted to scroll to the bottom of the page using vanilla JS, but I encountered a problem. The code below is supposed to scroll to the bottom of the page: window.scrollTo(0,document.body.scrollHeight); Whereas all it does is logs "undefined" in the console. Inputting document.body.scrollHeight returns an integer 736. Other than that, it doesn't matter what I input into the function's parameters, nothing happens. What more, it only happens on one website. What may matter (not sure) is that

问题 I have a SWT Text component, for which I set SWT.MULTI , SWT.V_SCROLL and SWT.H_SCROLL to show the scrollbar when required. I found that even content is smaller than the text component then also scrollbar are visible in disable state. Is there is any way through which I can auto hide the scrollbar? Like java Swing has JScrollPane.horizontal_scrollbar_as_needed 回答1: That works on all cases: Text text = new Text(parent, SWT.MULTI | SWT.H_SCROLL | SWT.V_SCROLL); Listener scrollBarListener = new

问题 I have a double scroll bar on my website in Chrome and Firefox (both browsers are up to date). I have been researching the web and stackoverflow and have tried following suggested options on the html element: html { overflow: hidden; } - afterwards - html { overflow: auto; } - and - html { overflow: scroll; } None of them got rid of the double bar, even worse some blocked me from scrolling at all. I'm not sure which other element to target or what might be causing this. Does anyone have a

问题 At first I thought you could use this rule which works for desktop Chrome: ::-webkit-scrollbar { display: none } But it didn’t work. After messing with webkit-scrollbar and its other selectors, I realized that this thing might not be part of the webkit-scrollbar after all: That’s why it’s not affected to whatever rules I make for webkit-scrollbar . That floating scroll indicator thing only appears when you scroll a page. For context, I’m trying to hide that thing for a website I’m using for

问题 I have an element with position: absolute in body with some part of it to the left from left side. #test{ position: absolute; height: 100px; width: 100px; left: -50px; background-color: lime; } I expect that horizontal scrollbar should appear allowing to scroll the document to the hidden part of the element, but it doesn't. So, I have some questions about the case: Why it happens so, why scrollbar doesn't appear (it works fine with symmetric layout on the right side)? Is it ever possible to

问题 Using z-index CSS property on 'fixed' positioned elements gives me a strange behavior under Chrome. When Firefox and Opera browsers give me the awaited result, Chrome does not seem to respect the z-index property, displaying the scrollbar above the red overlay (see code and Fiddle bellow). HTML: <div class="left"> <div class="placeholder"></div> </div> <div class="right"></div> <div class="overlay"></div> CSS: .left { background-color: yellow; bottom: 0; left: 0; overflow: auto; position:

问题 Is it possible to change the width of a tk Combobox scrolldown bar in python 2.7? I'm not talking about the combobox width, but rather the scrollbar width on the combobox that appears when the combobox is active. For example: self.cmbSortOrder=ttk.Combobox(self.frame2, value=l, textvariable=self.SortOrder) self.cmbSortOrder.bind("<<ComboboxSelected>>", self.reloadList) self.cmbSortOrder.pack(side=LEFT) 回答1: you can do it using configure() : This class is used to manipulate the style database.

问题 I want to have a custom scroll bar in Chrome. So, I'm using this sass: ::-webkit-scrollbar { width: 0.5em; height: 0.5em; } ::-webkit-scrollbar-thumb { background-color: rgba(255,255,255,.1); border-radius: 3px; &:hover { background: rgba(255,255,255,.2); } } My problem is that I want this scrollbar style only in an specific div. But if I do: #boardslist { ::-webkit-scrollbar { width: 0.5em; height: 0.5em; } ::-webkit-scrollbar-thumb { background-color: rgba(255,255,255,.1); border-radius:
