问题 Is it possible to draw a crescent moon using SVG in HTML? I've been trying things out at W3 Schools but I don't see an example of this. I don't need any of the shading that you see in typical google images of 'crescent moon', just a solid border crescent moon. 回答1: Please note that my solution might not be the best. I am not an expert when it comes to vector graphics and you should definitely look for other solution The approach I took is to draw another image with the same background. It

问题 http://jsbin.com/ararar/5/edit tl;dr The above link is a quick example of the problem further described below. Click on the li:s to remove them, and see the rendering glitch in IE9 or IE10. In an app that my team is building, we have a box for search results, that changes in height depending on the number of matches. The element has a box-shadow applied to it. The problem is in IE9 and IE10, when the box becomes smaller. It seems like IE will "forget" about the box-shadow, and only re-render

问题 I've found http://www.colorzilla.com/gradient-editor/ to be great for generating CSS3 gradients. However, there's one thing about it which would be great if someone could clarify for me. As I understand it, IE9 doesn't support the filters in the same way IE6-8 did, and doesn't support CSS3 gradients either. Colorzilla gives a very clever way of forcing IE9 to work with multi stop gradients, by including SVG data for the gradient in the CSS, and setting filter to none for IE9 only on any

问题 I did some research on Android about CSS3 animation (transformation with webkit-transition). The CSS3 animation is still an experimental feature in Webkit. If you try to do translation and scaling at the same time, you'll find a few glitches and/or bugs in the CSS Animation (for example, see http://www.youtube.com/watch?v=vZdBVzN1B8Y ). In other words, in many versions of Android the property -webkit-transform:matrix(...) does not work correctly. The only correct way to get scaling and

问题 Alright, so I'm trying to implement text-shadow across various browsers. I have IE6, IE7, FF, Chrome, and Opera all working... but IE8 wont' show any shadows unless it is in 'Compatibility View'. I've looked at a number of 'solutions' via search / Google, but the shadow is still only appearing in 'Compatibility View'. Any ideas on how to get it to show up without having to change modes? Note: Using HTML5 Boilerplate and Modernizr. edit: Added that I'm using Modernizr, and I clicked the wrong

问题 I've made a grid template with rows of 1fr 1fr 1fr. In the middle row, there are a list of inline images. In Chrome and Firefox, the images respect the height of the grid row and adapt properly. However, in Safari 10.1.2 and Safari TP 31, there appears to be a combination of the images overflowing the row and not scaling the image widths appropriately. Perhaps I'm doing something wrong? Or is this a Safari bug? And if so, is there a workaround? Safari 10.1 Safari TP Chrome 60 #grid { height:

问题 I've answered a question on how to start an animation when hovering the child element and then preserve the applied style until un-hovering the parent. However, I discovered a behaviour in my proposed solution that I can't explain and that I would like to understand. Reading the relevant parts of the specification didn't help me. Here is a minimal example showing the expected behaviour. It works but the properties with comments behind have to be different for some reasons. Otherwise (e.g.

问题 Is there a javascript framework out there that will use CSS3 Transitions for effects like changing opacity or moving elements but will fall back to using javascript setInterval/setTimeout if it is not supported? 回答1: Check out the YUI 3 Transition module, it does just that. 回答2: Check out Addy Osmani's article. It is a good summary of the current solutions with jQuery, specifically: jquery.transition.js by Louis-Rémi Babé jQuery.animate-enhanced.js by Ben Barnett 回答3: You could look at using

问题 After coming back to web-development after a four year hiatus, I am having a tough time vertically aligning the contents of a bootstrap 3 column with the next column. I have tried searching this site as well as generic searches in general and have just not come up with the right solution ... or my search terms are poor. In the HTML/CSS below, I would like to vertically center the "Page Title" text in the left column. I would like to keep the HTML and CSS as concise as possible while using the
