当show hide bootstrap 3 offcanvas在媒体宽度> 768px时的CSS3动画

Question

我正在使用bootstrap通用offcanvas工作正常.但是,sidebar当屏幕宽度超过768px时,我希望扩展折叠,同时在两个屏幕上使用css3同步动画div.我想要css only方法来做这个,如果css不工作,那么jquery也没关系.

这是我到目前为止尝试的,这是一个全屏视图.

因为我用width: 0;和height: 0;为#sidebarDIV,它不是很好的动画.使用现有的offcanvas方法有没有办法这样做？我不想更改HTML标记.

HTML

<!-- Navbar Tag Removed to reduce space -->
<!-- /.navbar -->
<div class="container">
    <div class="row row-offcanvas row-offcanvas-left">
        <div class="col-xs-8 col-sm-3 sidebar-offcanvas" id="sidebar" role="navigation">
            <h4>Menu</h4>
            <!-- Content Removed -->
        </div>
        <!--/span-->
        <div class="col-xs-12 col-sm-9 col-main">
            <p>
                <button type="button" class="btn btn-primary btn-xs" data-toggle="offcanvas">Toggle
                    nav</button>
            </p>
            <div class="jumbotron">
                <h1>Hello, world!</h1>
                <p>This is an example to show the potential of an offcanvas layout pattern in Bootstrap.
                    Try some responsive-range viewport sizes to see it in action.</p>
            </div>
            <!-- Content Removed  -->
            <!--/row-->
        </div>
        <!--/span-->

    </div>
    <!--/row-->

</div>
<!--/.container-->

CSS

html,   body {
  overflow-x: hidden; /* Prevent scroll on narrow devices */
}

@media (min-width: 768px) {
    html,   body {
    overflow-x: auto; /* allow scroll */
    }
    .container {
        max-width: 100%;
        width: 100%;
    }
/*Off Canvas */
    .sidebar-offcanvas, .col-main {
        position: relative;
        -webkit-transition: all .25s ease-out;
         -o-transition: all .25s ease-out;
            transition: all .25s ease-out;
  }
    .side-toggle .sidebar-offcanvas {
        left: -100%;
        width: 0;
        height: 0;
  }
    .side-toggle .col-main {
        width:100%;
    }
}

JQUERY

$(document).ready(function () {
    if ($(window).width() < 768) {
        $('[data-toggle="offcanvas"]').click(function () {
            $('.row-offcanvas').toggleClass('active');
        });
    }
    if ($(window).width() > 768){
        $('[data-toggle="offcanvas"]').click(function () {
            $('.row-offcanvas').toggleClass('side-toggle');
        });
    }
});
$(window).resize(function () {
    if ($(window).width() < 768) {
        $('[data-toggle="offcanvas"]').click(function () {
            $('.row-offcanvas').toggleClass('active');
        });
    }
    if ($(window).width() > 768){
        $('[data-toggle="offcanvas"]').click(function () {
            $('.row-offcanvas').toggleClass('side-toggle');
        });
    }
});

更新

1. 当屏幕分辨率大于768px时,切换按钮应该像两个cols,即div #sidebar和.col-maindiv 的切换宽度一样.在 #sidebar需要与线性动画被隐藏而.col-main'div的宽度应再次点击时被扩展到100%的宽度,反之亦然.
2. 当屏幕分辨率小于768px时,offcanvas应该像通用的Bootstrap Offcanvas模板一样.
3. 在调整浏览器大小时,脚本应该检查屏幕分辨率并按照上面提到的1和2点进行相应的操作.

这是你想要的吗？http://jsbin.com/yageheruludo/4/edit

我换了JS:

   $('[data-toggle="offcanvas"]').click(function () {
      $('.row-offcanvas').toggleClass('active').toggleClass('side-toggle');
   });
   $(window).resize(function () {
      if ($(window).width() < 768) {
          $('.row-offcanvas').removeClass('animate');
      } else {
          $('.row-offcanvas').addClass('animate');
      }
   });

和CSS:

  .sidebar-offcanvas, .col-main {
    position: relative;
  }
  .animate .sidebar-offcanvas, .animate .col-main {
    -webkit-transition: all .25s ease-out;
         -o-transition: all .25s ease-out;
            transition: all .25s ease-out;
  }
  .side-toggle .sidebar-offcanvas {
    width: 0;
    padding: 0;
    overflow: hidden;
  }

编辑

在第一个窗口调整大小之前,动画不起作用.

将js更改为:

   $('[data-toggle="offcanvas"]').click(function () {
      $('.row-offcanvas').toggleClass('active').toggleClass('side-toggle');
   });
   $(window).resize(function () {
      if ($(window).width() < 768) {
          $('.row-offcanvas').removeClass('animate');
      } else {
          $('.row-offcanvas').addClass('animate');
      }
   });
   $(window).trigger('resize'); // added this line

你是什​​么意思"改变持续时间后不动画(......)"？你的意思是"方向"？
