Material 设计网格宽度未对齐

Material Design Grid Widths not aligning up

Fiddle: http://jsfiddle.net/hectooorr/dcwt3to2/

我有两个问题。无法将 2 个容器并排对齐。无法获得一致的宽度。

第一个问题: 当两个容器的宽度均为 50% 时,如何让它们并排对齐?在下面的场景中,我总是有两个容器,每个容器的宽度为 50%。当我这样做时,我的容器没有对齐。应该将这 2 个添加到它们自己的行中,并将 50% 添加到一个并向另一个添加 flex?

<div layout="row" layout-margin layout-fill layout-wrap class="custom-chart-list">
<div flex="100" class="custom-container">container 1: 100% width - why does this width exceed width of containers 2 and 3?</div>
<div flex="50">container 2: 50% width</div>
<div flex="50">container 3: 50% width</div>
<div flex="100" class="custom-container">100% width</div>
<div flex="50">container 4: 50% width</div>
<div flex="50">container 5: 50% width - Why won't this stack next to container 4?</div>

第二个问题: 为什么 flex="100" 的容器超过 2 个容器的宽度各 50%?请参见下面的示例。第一行的弹性值为 100。第二个容器的弹性值为 50,第三个容器只有 'flex' 属性。

这是我的解决方法 http://jsfiddle.net/hectooorr/etmpLnkv/
