问题 I am trying to detect a mouseover event on a circle. I define the circle div like this: .circle { width: 80px; height: 80px; -moz-border-radius: 40px; -webkit-border-radius: 40px; background-color: #33f; } Then I detect the mousover using jQuery like this: $('.circle').mouseover(function() { $(this).css({backgroundColor:'#f33'}); }); This works well, except that the entire 80px by 80px area triggers the mouseover event. In other words, just touching the bottom right corner of the div triggers

问题 I'm running into a problem with WebKit browsers (Chrome 15.0.x and Safari 5.1.1) where box shadows are not being rendered on text inputs. Just by chance, I discovered that explicitly setting the border causes the box shadow to render, even if you set the border to 'none' or the default, 'inset'. The code below (view it in action on JSFiddle) demonstrated the problem when viewed with Chrome or Safari, but it renders as expected in Firefox 6.0.2 and Opera 11.52. HTML <input type="text" value=

问题 I have a collapsible list implemented using HTML and CSS. The list works properly, but I need a little modification. Whenever I click an item in the list it expands. But as I click on another item in the same list, the previously expanded element gets collapsed while the clicked one gets expanded. Please help me to apply the behavior that makes it possible to expand multiple list items at the same time. I want it to be done in HTML and CSS only. Here is the implementation I currently have.
