The easiest way to determine the size and position of an element is to call its getBoundingClientRect() method. This method returns element positions in viewport coordinates. It expects no arguments and returns an object with properties left, right, top, and bottom. The left and top properties give the X and Y coordinates of the upper-left … Read more
+1 to the very nice and ilustrative image. I know it’s an old question, but I casually found the same question posted by you in forum.jquery.com and one answer there (by@tucker973), suggested one nice library to make this and wanted to share it here. It’s called sticky-kit by @leafo github project webpage simple example in … Read more
.outside { width: 200px; height: 200px; background-color: #EEE; /*to make it visible*/ } Needs to be .outside { position: relative; width: 200px; height: 200px; background-color: #EEE; /*to make it visible*/ } Absolute positioning looks for the nearest relatively positioned parent within the DOM, if one isn’t defined it will use the body.
Sorry, there’s no generic library function to do this. Go doesn’t have a straight forward way of writing a function that can operate on any slice. Your function works, although it would be a little better if you wrote it using range. If you happen to have a byte slice, there is bytes.IndexByte.
Change the position attribute to fixed instead of absolute.
2022 UPDATE. This answer is nearly 10 years old. When it was written we didn’t have layout technologies like Flex or Grid available (they were dark, hacky/fun times). Thankfully things have massively improved. Jöcker’s answer shows you how to achieve this layout with Grid. If you can live with not supporting legacy browsers, do that … Read more
Wrap the child you want centered in a View and make the View absolute. <View style={{position: ‘absolute’, top: 0, left: 0, right: 0, bottom: 0, justifyContent: ‘center’, alignItems: ‘center’}}> <Text>Centered text</Text> </View>
Use position:absolute; right: 0; No need for float:right with absolute positioning Also, make sure the parent element is set to position:relative;
Couldn’t you use width: calc(50% – 24px); for your cols? Then set your margins.
RecyclerView is designed to be extensible, so there is no need to subclass the LayoutManager (as droidev suggested) just to perform the scrolling. Instead, just create a SmoothScroller with the preference SNAP_TO_START: RecyclerView.SmoothScroller smoothScroller = new LinearSmoothScroller(context) { @Override protected int getVerticalSnapPreference() { return LinearSmoothScroller.SNAP_TO_START; } }; Now you set the position where you want … Read more
