flexbox中的垂直和水平文本对齐

Question

在这种情况下，如何简单地更改flex框中的文本对齐？

我想将文本与flex-start对齐，但出现了问题，我不明白是什么。我认为主要风格不会改变，或者在这种情况下我需要使用别的东西，而不是align-items。我需要将所有文本（md-card-title，md-card-subtitle,md-card-content）与flex-start对齐。

goods.component.css：

md-card { 
    display: flex; 
    flex-direction: column; 
    justify-content: space-around; 
    align-items: stretch; 
    width: 500px; 
    margin-top: 25px; 
    margin-bottom: 25px; 
} 

md-card-title { 
    font-size: 32px; 
    align-items: flex-start; 
    justify-content: flex-start; 
} 

md-card-subtitle { 
    align-items: flex-start; 
    justify-content: flex-start; 
} 

md-card-content { 
    align-items: flex-start; 
    justify-content: flex-start; 
} 

md-grid-tile { 
    align-items: flex-start; 
    justify-content: flex-start; 
} 

h1 { 
    color: #673ab7; 
    text-align:center; 
    margin: 1em 0 0.5em 0; 
    font-weight: 100; 
    text-transform: uppercase; 
    font-style: italic; 
    font-family: 'Josefin Sans', sans-serif; 
    font-size: 58px; 
    line-height: 54px; 
    text-shadow: 2px 5px 0 rgba(0,0,0,0.2); 
} 

a { 
    font-size: 24px; 
    text-decoration: none; 
    color: #673ab7; 
} 

.price-content{ 
    font-size: 18px; 
    background: #00bd0d; 
    float: left; 
    height: 22px; 
    line-height: 22px; 
    padding: 0px 9px 0px 9px; 
    color: #ffffff; 
    margin-bottom: 8px; 
} 

goods.component.html：

<h1>All goods</h1> 
<md-card> 
<md-grid-list cols="3" rowHeight="3:1"> 
    <md-grid-tile [colspan]="1" [rowspan]="3"> 
     <img md-card-image src='./assets/image/001.jpeg' alt='picture'> 
    </md-grid-tile> 
    <md-grid-tile [colspan]="2" [rowspan]="1"> 
     <md-card-title><a [routerLink]='["/goods"]'>Audi A8</a></md-card-title> 
    </md-grid-tile> 
    <md-grid-tile [colspan]="2" [rowspan]="1"> 
     <md-card-subtitle>Description Description Description Description Description Description Description Description Description</md-card-subtitle> 
    </md-grid-tile> 
    <md-grid-tile [colspan]="2" [rowspan]="1"> 
     <md-card-content class="price-content">50000 $</md-card-content> 
    </md-grid-tile> 
</md-grid-list> 
</md-card> 

Answer 1

由于justify-content/align-items属性用于/柔性容器设置，这些属性元素还需要dispay: flex，否则他们不会有任何效果。

而且在这种情况下，这4条规则

md-card-title 
md-card-subtitle 
md-card-content 
md-grid-tile 

一些使用并不需要设置的属性，因为它是它们的默认值（见CSS注释）

Answer 2

的Flexbox将仅适用于直接子元素。您尝试将“Flexbox-Area”之外的元素对齐。该md-grid-list还需要display: flex;
