问题 I\'m coding a \"popup window\" in JavaScript and I\'ve come across an interesting thing: The navy square under the popup window is visible even though I would expect it to be hidden. The popup was added after the square, so it should be on the top. CSS opacity property of the navy square is 0.3 . From what I\'ve tried, it seems that every number from the interval (0,1) would yield the same result. If I change it to 1 , then it behaves as expected (i.e. the part of the square under the popup

问题 I\'m using CSS to indicate the trigger text for a jQuery slide-down section: i.e. when you hover over the trigger text the cursor changes to a pointer and the opacity of the trigger text is reduced to indicate that the text has a click action. This works fine in Firefox and Chrome, but in IE8 the opacity doesn\'t change. I\'ve tried a variety of CSS settings without any success. For example HTML: <h3 class=\"slidedownTrigger\">This is the trigger text</h3> CSS: .slidedownTrigger { cursor:

How can I set the opacity or transparency of a Panel in WinForms?

问题 I was wondering how to change or modify the transparency of a Panel in C#, not the whole form, but the panel only.. I\'ve seen many C# tutorials on Opacity, but its for the Form. im looking for how it could be possible with the Panel only. Thank You! 回答1: Yes, opacity can only work on top-level windows. It uses a hardware feature of the video adapter, that doesn't support child windows, like Panel. The only top-level Control derived class in Winforms is Form. Several of the 'pure' Winform

问题 This question already has answers here : How to affect other elements when one element is hovered (6 answers) Closed 5 years ago .

Is there a way to actually do
