我粘贴在具有包含四个子div的容器类的div的HTML代码片段的下面，该子div的类名为“city”。无法在一条直线上对齐div标签的文本框（css边框）

我想通过应用bootstrap将它们排成一行。

我已将我的样式表粘贴到HTML下面。我一直试图通过增加和减少右侧/左侧边距一个多小时，但无法正确使用它。

<!DOCTYPE html> 
 
<html lang="en-us"> 
 
<head> 
 
    <link rel="stylesheet" type="text/css" href="./index.css"> 
 
    <link rel="stylesheet" type="text/css" href="../css/bootstrap.min.css"> 
 
</head> 
 
<body> 
 

 
<div class="container"> 
 
    <h1 id="cities">Cities Of The World</h1> 
 
    <div class="city"> 
 
    <h2>London</h2> 
 
    <p>London is the capital city of England.</p> 
 
    <p>It is the most populous city in the United Kingdom, with a metropolitan area of over 13 million inhabitants.</p> 
 
    </div> 
 

 
    <div class="city"> 
 
    <h2>Paris</h2> 
 
    <p>Paris is the capital of France.</p> 
 
    <p>The Paris area is one of the largest population centers in Europe, with more than 12 million inhabitants.</p> 
 
    </div> 
 

 
    <div class="city"> 
 
    <h2>Tokyo</h2> 
 
    <p>Tokyo is the capital of Japan.</p> 
 
    <p>It is the center of the Greater Tokyo Area, and the most populous metropolitan area in the world.</p> 
 
    </div> 
 

 
    <div class="city"> 
 
    <h2>New York</h2> 
 
    <p>The City of New York is the most populous city in the United States.</p> 
 
    <p>New York is an important center for international diplomacy and has been described as the cultural and financial capital of the world.</p> 
 
    </div> 
 
</div> 
 
</body> 
 
</html>

#cities { 
    text-align: center; 
    padding: 20px; 
} 
.city { 
    display: inline-block; 
    margin: 10px; 
    padding: 15px; 
    max-width: 250px; 
    height: 300px; 
    border: 1px solid black; 
}

使用CSS Flexbox的：

包装你.city到父<div>（在我的情况.city-holder）Flex容器。像：

.city-holder { 
    display: flex; 
}

看一看下面的代码片段：

.city-holder { 
 
    display: flex; 
 
}

<!DOCTYPE html> 
 
<html lang="en-us"> 
 
<head> 
 
    <link rel="stylesheet" type="text/css" href="./index.css"> 
 
    <link rel="stylesheet" type="text/css" href="../css/bootstrap.min.css"> 
 
</head> 
 
<body> 
 

 
<div class="container"> 
 
    <h1 id="cities">Cities Of The World</h1> 
 
    <div class="city-holder"> 
 
    <div class="city"> 
 
    <h2>London</h2> 
 
    <p>London is the capital city of England.</p> 
 
    <p>It is the most populous city in the United Kingdom, with a metropolitan area of over 13 million inhabitants.</p> 
 
    </div> 
 

 
    <div class="city"> 
 
    <h2>Paris</h2> 
 
    <p>Paris is the capital of France.</p> 
 
    <p>The Paris area is one of the largest population centers in Europe, with more than 12 million inhabitants.</p> 
 
    </div> 
 

 
    <div class="city"> 
 
    <h2>Tokyo</h2> 
 
    <p>Tokyo is the capital of Japan.</p> 
 
    <p>It is the center of the Greater Tokyo Area, and the most populous metropolitan area in the world.</p> 
 
    </div> 
 

 
    <div class="city"> 
 
    <h2>New York</h2> 
 
    <p>The City of New York is the most populous city in the United States.</p> 
 
    <p>New York is an important center for international diplomacy and has been described as the cultural and financial capital of the world.</p> 
 
    </div> 
 
    </div> 
 
</div> 
 
</body> 
 
</html>

或者使用Bootstrap Grids：

使用col-xs-*，看看下面的代码片段：

<!DOCTYPE html> 
 
<html lang="en-us"> 
 
<head> 
 
    <link rel="stylesheet" type="text/css" href="./index.css"> 
 
    <link rel="stylesheet" type="text/css" href="https://cdnjs.cloudflare.com/ajax/libs/twitter-bootstrap/3.3.7/css/bootstrap.min.css"> 
 
</head> 
 
<body> 
 

 
<div class="container"> 
 
    <h1 id="cities">Cities Of The World</h1> 
 
    <div class="row"> 
 
    <div class="col-sm-3 city"> 
 
    <h2>London</h2> 
 
    <p>London is the capital city of England.</p> 
 
    <p>It is the most populous city in the United Kingdom, with a metropolitan area of over 13 million inhabitants.</p> 
 
    </div> 
 

 
    <div class="col-sm-3 city"> 
 
    <h2>Paris</h2> 
 
    <p>Paris is the capital of France.</p> 
 
    <p>The Paris area is one of the largest population centers in Europe, with more than 12 million inhabitants.</p> 
 
    </div> 
 

 
    <div class="col-sm-3 city"> 
 
    <h2>Tokyo</h2> 
 
    <p>Tokyo is the capital of Japan.</p> 
 
    <p>It is the center of the Greater Tokyo Area, and the most populous metropolitan area in the world.</p> 
 
    </div> 
 

 
    <div class="col-sm-3 city"> 
 
    <h2>New York</h2> 
 
    <p>The City of New York is the most populous city in the United States.</p> 
 
    <p>New York is an important center for international diplomacy and has been described as the cultural and financial capital of the world.</p> 
 
    </div> 
 
    </div> 
 
</div> 
 
</body> 
 
</html>

希望这有助于！
