hover

问题 Posting this question largely in the hopes of confirming my suspicions of the behaviour, and thus documenting it for other programmers. (Since I found no record of this anywhere online) I have a site that I'm building, whose nav bar has the following properties: The horizontal section is a <ul> of <li> s and some of the <li> s hav both: A n <a> element taking you to that topic. A hover CSS selector that triggers display:block on a submenu - a nested <ul> which then drops down vertically. On a

问题 I have a thumbnail image. Upon mousing over this image, an entirely new image appears nearby, as intended. THE CHALLENGE The new image must remain once the hovering of the thumbnail is over. The new image should only disappear when the user mouses away from the new image. CSS-only Solution After experimenting for hours with CSS today, the best solution I devised involved the :hover pseudo-class, transition , and opacity . It's convoluted and complicated solution for what may be a simple task

问题 I want to show an overlay div sitting on top of the hovered div similar to this effect on IBM website: http://www.ibm.com/us/en/ Please look at the 3 boxes near the footer. Hover on the box "Let's build a smarter planet" to view the effect. 回答1: I've created a working example. Basically you need to create 3 divs with a visible and the invisible containers, add hover event handler and toggle the tooltip's visibility in that handler. HTML: <div class="parents"> <div class="box type-1">box 1<

问题 I've built a simple dropdown menu. The code and demo is here: http://jsfiddle.net/3Lq2d/5/ It looks like this: Mousing over MENU 1 fades in the Submenu s. It works great, unless you happen to be a spaz and jiggle your mouse around a lot over the menu, in which case it gets stuck in a semi-transparent state. Using .stop(true,true) fixes the spaz issue, but removes the ability to mouse down from the menu to the submenu. I am using fadeIn/fadeOut to give a slight delay, so when the mouse moves

问题 My page has 3 divs that are located horizontally. I need to make the 2 divs move to the sides of the page (left div move to left, and right div move to right) when the center div is on hover. I can make the left div move, but the right div isn't moving. I hope to get this achieved using CSS, if not please advise. Thanks a lot. My code is like the below: .container { position:absolute; bottom:0; right:0; left:0; margin-right:auto; margin-left:auto; width:50%; height:10%; } .a {position

问题 I have created a horizontal menu that when you hover an item, a drop down menu appears. This is all fine. However, when you leave the menu item (to use the drop down) the drop down disappears. I understand that this is because you are no longer hovering it, but how do I solve this? Note: I don't want the drop down menu directly below it, I want a reasonable gap between the menu item and drop down (as I have it at the moment). Thanks. HTML <header id="header"> <div class="container"> <a href="

问题 I am using classic Eclipse 3.6.1. I have a Java project which is throwing an exception because of a stack overflow. Unlike other editors, when I hover my mouse pointer on a variable it does not show me the value of that variable. Here are the settings in Window->Preferences->Java->Editor->Hovers Combined Hover - Shift Variable Values - Ctrl Source - Shift+Ctrl But this doesn't seem to be working. I have seen threads by others about this same problem but could not find a solution. Is this a

问题 I'm using the following code to show a box when you mouseover a certain div and have set the delay on the fade out but is there some way of cancelling the fadeOut effect if the user goes back on to the div? jQuery("#cart-box").hover(function() { jQuery("#cart-container").fadeIn('fast'); }, function( ) { jQuery("#cart-container").delay(800).fadeOut('fast'); }); Code for the divs <div class="cart-box" id="cart-box"><a href="#">Cart</a><div class="cart-container" id="cart-container"><div class=

问题 I have 5 clusters of x,y data I'm plotting using R 's plotly . Here are the data: set.seed(1) df <- do.call(rbind,lapply(seq(1,20,4),function(i) data.frame(x=rnorm(50,mean=i,sd=1),y=rnorm(50,mean=i,sd=1),cluster=i))) Here's their plotly scatter plot: library(plotly) clusters.plot <- plot_ly(marker=list(size=10),type='scatter',mode="markers",x=~df$x,y=~df$y,color=~df$cluster,data=df) %>% hide_colorbar() %>% layout(xaxis=list(title="X",zeroline=F),yaxis=list(title="Y",zeroline=F)) Which gives:

问题 I'm using the following JS code to build a horizontal image carousel that scrolls on hover. The mousemove event detects the position of the mouse over the container and scrolls to the left or to the right accordingly. Everything works as I expect but if I move the mouse over the container while the animation is running, it becomes a bit jerky. Is there any solution for this? Thanks JS: $( '.carousel-frame ul' ).mousemove( function(e) { var container = $(this).parent(); if ((e.pageX -
