twitter-bootstrap-4

Hi I'm using bootstrap4 beta. I noticed that it uses the classes; ml-auto or mr-auto, instead of pull-right and pull-left. I can guess l is left and r is right. What's the meaning of m beside l and r? Is it margin? It's short for: margin-left So ml-auto means margin-left: auto which aligns an element to the right. 来源： https://stackoverflow.com/questions/46160931/whats-the-meaning-of-ml-in-bootstrap-4

Bootstrap 4 Alpha 6 I cant seem to figure out how to get both the right links and left link to both collapse. Right now only the right hand side link collapses. <nav id="topNav" class="navbar fixed-top navbar-toggleable-sm navbar-inverse bg-inverse"> <button class="navbar-toggler navbar-toggler-right" type="button" data-toggle="collapse" data-target=".navbar-collapse"> Menu </button> <div class="navbar-collapse collapse"> <ul class="nav navbar-nav"> <li class="nav-item"> <a class="nav-link" href="#">Link</a> </li> <li class="nav-item"> <a class="nav-link" href="#">Link</a> </li> <li class="nav

Bootstrap 3 modal works fine: https://jsfiddle.net/qLy7gk3f/4/ But Bootstrap 4 modal doesn't: https://jsfiddle.net/qLy7gk3f/3/ The code is identical: $scope.click = function() { $uibModal.open({ templateUrl: "modal.html", controller: "modal", scope: $scope }); } How can I get AngularUI modals to work with Bootstrap 4? I think it's just a case of adding the .in classes, specifically: .fade.in { opacity: 1; } .modal.in .modal-dialog { -webkit-transform: translate(0, 0); -o-transform: translate(0, 0); transform: translate(0, 0); } .modal-backdrop.in { filter: alpha(opacity=50); opacity: .5; }

I have a little non-conventional DIV in this design as shown below. I could use a height and do it but I want it to change dynamically: For instance, if the DIV has more content and the height changes in one of the block on the right, the left DIV auto adjust it's height as well. I wonder if flex could help. Here's how it should change to: I have this HTML so far: <div class="container"> <div class="row row-eq-height"> <div class="col-sm-8 col-8"> <div class="black"> <p>Bar Graph or Line Graph</p> </div> </div> <div class="col-sm-4 col-4"> <div class="red"> <p>numbers</p> </div> <div class=

Is it possible to mix card of different sizes within a card-group in Bootstrap 4. I want to have a large card (double width) on the left size, and two smaller cards on the right, with the same height of all three. <div class="container"> <div class="row"> <div class="card-group"> <div class="card col-md-6"> <div class="card-block"> <h4 class="card-title">Card 1</h4> <p class="card-text">Text 1</p> </div> </div> <div class="card col-md-3"> <div class="card-block"> <h4 class="card-title">Card 2</h4> <p class="card-text">Text 2</p> <p class="card-text">More text 2</p> <p class="card-text">More
