问题 Using Jquery preferably, how do I detect if an element is within the viewable client area of a browser? I'm dynamically creating a menu from a dataset, and when the list grows too long, the height of the resulting menu causes part of it to fall below the browser bottom client area. How do I detect this and act accordingly? 回答1: I believe it should be possible to cook something up using position() and scrollTop() (add scrollLeft if your page is prone to horizontal scrolling). Here is some

问题 I have a problem in css, I have a TD with a width:100px; and height:100px; inside it, I have an img element with the same width and height (100px, 100px).

问题 While setting height of multiple components in a view, is there any difference between setting the height in terms of flex or height? For eg, 1) <View> <View style={{flex:1}}> </View> <View style={{flex:3}}> </View> </View 2) var windowSize = Dimensions.get('window'); <View> <View style={{height:windowSize.height/4}}> </View> <View style={{height:windowSize.height*3/4}}> </View> </View> 回答1: Yes, when you rotate a device flex is responsive where as window isn't.

问题 I know the squared solution with :before { padding-bottom } . This works only with a width value, because padding is always using a relation to the parents width. - But exactly this is my problem. I ONLY have the value of the a fixed HEIGHT (by parent container) and I need squared boxes by that height value. I don't like to use JS. If there is a solution to REPLACE the STATIC WIDTH value with pure CSS, please tell me! Here's a simple code sample: div.wrapper { height: 70px; padding: 5px;

问题 How do I get my <textarea> to have a height of 100% and work in IE7/6? height:100% works fine in all other browsers but IE just doesn't want to accept anything other than specific values.

If you want to make the element the full-length of your page, apply height:100%; to both the html and body elements. /*100% height of the parent

问题 Again, I'm quite new to jQuery and there are still many things that seem simple yet get me stuck for hours. Right now, I'm trying to replace the target of a link. That I know how to do. But the thing is, the target has to change based on the div currently displayed. Here's the wireframe : The link, of course, is on the arrow, which is fixed at the bottom of the viewport.
