hover

问题 I have a DIV which changes bgcolor to blue when :hover. Button click adds class which animates bgcolor to green. But now :hover wont work (bgcolor wont change to blue). Why? http://jsfiddle.net/EstSiim/me7t055c/ HTML: <div class="box"></div> <button class="animate-btn">Animate</button> CSS: .box { background-color: red; width: 200px; height: 200px; } .box:hover { background-color: blue; } .trigger-bg-change { -webkit-animation: bg-change 1s ease 0 1 forwards; animation: bg-change 1s ease 0 1

问题 Original issue: OpenLayers 3 (tested also newest 3.14.1) should have some sense in the way it selects features that overlap each other. When multi=false it selects only one feature, but picks it quite randomly. When you hover over certain features from different directions, different feature is selected. I have tried to tangle this by setting z-index to features to tell Openlayers the desired order. Indexing is set to order point > line > polygon but still I am not getting point selected

问题 I have a nice little hover effect on my website that quickly transitions in as the user hovers over a link. But when the user leaves hovering over the box, the shadow (and other traits) go away immediately, instead of fading back out. Is there a way I can get the properties to fade both in AND out, maybe using some sort of :un-hover type pseudo class? Thanks! And here is the CSS block if it helps: a.squares:hover, a.squares:active { color: black; background-color: #E8E8E8; box-shadow: 0 0

问题 I'm running into an issue with my Selenium script on Python. In the javascript web application that I'm interacting with, an element I need to click doesn't exist until I hover over it. I've looked and found various answers on how to hover, but the sequence needs to include the clicking of a new element during the hover event. Here is the code I am currently working with. The element is renamed from add to add1 when a hover occurs, once add1 exists; I should be able to click/send.keys to

问题 The CSS3 doc talks about :hover and :focus, which seem exactly the same to me. What are the differences between the two? What am I not seeing? Thanks! 回答1: Hover is 'true' when the mouse pointer is over an element. Focus is true if the cursor is in that element. It's possible for hover to be false and focus true (e.g click in a text field then move the mouse away) 回答2: :hover applies to any element that the mouse cursor is currently over. :focus refers to form focus, and is the current form

问题 How can I change the style of another element when a link is hovered - without jQuery/ JavaScript? ul>li>a:hover main { opacity: 0.1; } main p { font-size: 200px; } <header> <ul> <li><a href="#">Hover me</a></li> </ul> </header> <main> <p>Hello World!</p> </main> I want to change the opacity of the text in main when the link is hovered.
