问题 What is the best way to set the transparency of a HTML DIV element and its contents using jQuery? 回答1: $('#my_element').css({ 'opacity' : 0.7 }); Do you want to actually set the opacity to each of the contained elements as well, or you just want it to 'appear' as if the child elements have the same opacity? As an example to my question, if you wanted something that sets an element, and each of the children elements, you could do something like this html <div id="my_element"> <div> lorem </div

问题 does anybody know if the following image could be made in CSS? Light and dark lines could and should be equal width and edges fade in to darker color so that overall background would be dark color (dark blue in this case). Any help is well appreciated. My google skills didn't provide any help on this kind of effect, only 'starburst stickers / badges kind of things' was found. 回答1: No. Sadly, the css3 generated image specs do not include conical/angular gradients (though they might come out in

问题 I've seen a number of pixel-shader effect examples, stuff like swirl on an image. But I'm wondering if anyone knows of any examples or tutorials for more practical uses of shader effects? I'm not saying that a swirl effect doesn't have it's uses, it's just that many of the examples I've found have the basic effect explained and don't go into how it might be used subtly with another effect or transition to produce a wonderful effect.

This is a video of a very nice ripple effect done through OpenGL. I don't have any experience yet with OpenGL and was wondering if it is still possible to create a 2D water effect on the live

问题 When rendering a scene of textured polygons, I'd like to be able to switch between rendering in the original colors and a "grayscale" mode. I've been trying to achieve this using blending and color matrix operations; none of it worked (with blending I couldn't find a glBlendFunc() that achieved something remotely resembling to what I wanted, and color matrix operations ...are discussed here). A solution that comes to mind (but also is rather expensive) is to capture the screen every frame and
