Chrome浏览器中具有Flexbox水平居中布局的隐藏内容

Question

基于this example，我尝试使用flex CSS将内容水平居中，通常情况下它是正确的。但是，当内容很大时，左侧部分将隐藏起来。它发生在Chrome中，而水平滚动条则无济于事。如您在代码段中所见。我必须做些什么才能使其正确？

.flex-container {
    padding: 0;
    margin: 0;
    display: -webkit-box;
    display: -moz-box;
    display: -ms-flexbox;
    display: -webkit-flex;
    display: flex;
    align-items: center;
    justify-content: center;
}
.row {
    width: auto;
    border: 1px solid blue;

}
.flex-item {
    background-color: tomato;
    padding: 0px;
    white-space: nowrap; /* added to simulate large content */
    margin: 0px;
    color: white;
    font-weight: bold;
    font-size: 2em;
    text-align: left;
}

<div class="flex-container">
    <div class="row"> 
        <div class="flex-item">hidden.............................somewhere.....................................................................................................end</div>
        <div class="flex-item">where</div>
        <div class="flex-item">I</div>
        <div class="flex-item">am?</div>
    </div>
</div>

如您所见，这是使用flexbox解决此问题的另一种方式：here

Answer 1

请尝试以下代码。

ConcurrentBag<T> list = new ConcurrentBag<T>();
Parallel.ForEach(listSource, entity =>
{
    T entityCloned = GetEntityClone(entity); //Taking 800ms totally
    if (entityCloned != null)
        list.Add(entityCloned);

});

var listVersion = list.ToList();

html, body {
    height: 100%;
}
body {
    margin: 0;
}
.flex-container {
    width: 100%;
    padding-right: 15px;
    padding-left: 15px;
    margin-right: auto;
    margin-left: auto;
}
.row {
    display: -webkit-box;
    display: -ms-flexbox;
    display: flex;
    -ms-flex-wrap: wrap;
    flex-wrap: wrap;
    margin-right: -15px;
    margin-left: -15px;
}
.flex-item {
    background-color: tomato;
    margin: 0px;
    color: white;
    font-weight: bold;
    font-size: 2em;
    text-align: left;
    max-width: 100%;
    flex-grow: 1;
    padding-right: 15px;
    padding-left: 15px;
}

class Model extends Resource {
    public async static get(): Promise<Model[]> {
        return super.fetch({ url: 'custom-url?query=params' }) as Promise<Model[]>;
    }
}

.flex-container {
    padding: 0;
    margin: 0;
    display: -webkit-box;
    display: -moz-box;
    display: -ms-flexbox;
    display: -webkit-flex;
    display: flex;
  flex-direction:column;
    align-items: center;
    justify-content: center;
}

.flex-item {
    background-color: tomato;
    padding: 0px;
    white-space: nowrap; /* added to simulate large content */
    margin: 0px;
    color: white;
    font-weight: bold;
    font-size: 2em;
    text-align: left;
}
