flexbox

问题 I have this structure in bootstrap columns: And I want you to change to a lower resolution, be ordered as follows: I found how to do it with flexbox here: Flexbox: reorder and stack columns But I can not change the entire structure of my project to flexbox, so I want to know if with bootstrap 4, it is possible to do so. Thank you very much. My poor test. @import url( 'https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0-alpha.6/css/bootstrap.min.css' ); div { text-align: center; height: 60px; }

问题 I wanted to use flexbox with a column layout, but I wanted the top n - 1 flex items to be pinned to the top and the nth flex item to be pinned to the bottom of the main flex container area. I solved this by using the nth flex item to also be a new flexbox/flex container using justify-content: flex-end , but I couldn't find any examples that were doing this - so is this a correct/acceptable solution according to the standard and, if not, how would I otherwise go about this with flexbox? Here's

问题 How can I configure flexbox to have a nice fallback? Say I have this: .parent{ display: flex; flex-flow: row wrap; width: 320px; border: 1px solid black; } .children{ text-align: center; flex: 1; background: #DDD; } <div class="parent"> <div class="children">1</div> <div class="children">2</div> <div class="children">3</div> </div> What rules am I allowed to add to have a nice fallback for older browsers and that they get completly ignored and don't disturb flexbox.

问题 I am about to deploy my first React Native application to the iOS app store. I am having a problem however when it comes to layout. I am utilizing the flexbox system and currently designing for iPhone 6. I have done all the mockups and Sketch and have everything how I would like it to look. I have run into a problem however whenever I try to run the application in iPhone 4. The design that I have implemented for the iPhone 6 does not fit with the constraints that iPhone 4 possesses. I can try

问题 I currently have elements within a container, each of which contains an image. I want to distribute these into the four corners or the container, using flexbox. The images are distributing correctly horizontally, but don't take up all the available space vertically. Here's what it looks like at the moment: Here's my markup: <div class="container"> <div class="photo"> <img src="https://placehold.it/180"> </div> <div class="photo"> <img src="https://placehold.it/180"> </div> <div class="photo">

问题 I'm trying to create a layout (which will be a music player) with flex. I have 3 buttons (previous, play, and next, represented by the red squares) which I always want to be on the same line. I then have some song info (current time, song title, and total time) that I want to display to the right of the buttons. I pretty much always want the total time to be on the far right and for the song title to fill up the remaining width (with flex-grow ), but to truncate with ellipsis as the window

问题 I have a container with a fixed width and variable height. I'm filling the container with an unknown amount of elements. I'd like the elements to arrange themselves in columns, from top to bottom and then left to right. I could use column , but I don't know the maximum width of the child elements, so I can't set a column-width or column-count . I think display: flex with flex-flow: column wrap is the way to go, but if I maintain height: auto on the container, it will generate as a single

问题 This question already has answers here : Flexbox, z-index & position: static: Why isn't it working? (1 answer) Understanding z-index stacking order (1 answer) Closed 2 years ago . I'm trying to have two columns, one being a menu which can expand and overlap the other column. But I used a flex element to wrap these columns and my menu expands behind the other element, even with a greater z-index . The render is something like this: .main { font-family: 'Open Sans', Helvetica, sans-serif;

问题 I have a parent element, with two elements inside: <div class="parent"> <div class="child"> one </div> <div class="child"> two </div> </div> Currently, the .parent is 100% wide. I would like it only to be the width of the two children. .parent { display: flex; background-color: aliceblue; } How can I make the parent to be the width of it's contents, and not wider?
