Question

所以我从下而上自学HTML和CSS。我只是想自学CSS Flexbox。

我想开始做两个简单的专栏，但是由于某种原因它们重叠了，我不知道为什么。

正如您所看到的，我几乎在所有尝试中都尝试使用padding：0和margin：0来摆脱它，但是我似乎无法修复它，所以这一定是我还没有学过的属性< / p>

以下是代码：

html：

<!doctype html>
<html lang="en">
  <html>
  <link href='https://fonts.googleapis.com/css?family=Pacifico' rel='stylesheet' type='text/css'>

  <head>
    <meta charset="utf-8">
    <meta http-equiv="X-UA-Compatible" content="IE=edge">
    <meta name="viewport" content="width = device-width, initial scale = 1">

    <link rel="stylesheet" type="text/css" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css">
    <link rel="stylesheet" type="text/css" href="styles/main.css">
  </head>

  <body>
    <div class="flex-container">
      <div class="row">
        <div class="flex-item">1</div>
        <div class="flex-item">2</div>
        <div class="flex-item">3</div>
        <div class="flex-item">4</div>
      </div>
      <div class="row2">
        <div class="flex-item">1</div>
        <div class="flex-item">2</div>
        <div class="flex-item">3</div>
        <div class="flex-item">4</div>
      </div>
    </div>

CSS：

html,
body {
  height: 100%;
  padding: 0px;
  width: 100%;
}

body {
  margin: 0;
  padding: 0px;

.flex-container {
  height: 100%;
  padding: 0;
  margin: 0;
  display: -webkit-box;
  display: -moz-box;

}

.row {
  width: 50%;
  border: 1px solid blue;
  padding: 0px;
  height: 100%;
}

.row2 {
  width: 50%;
  border: 1px solid blue;
  padding: 0px;
  margin-right: 0px;
  height: 100%;
}

.flex-item {
  background-color: tomato;
  padding: 0px;
  width: 20px;
  height: 20px;
  margin: 10px;
  line-height: 20px;
  color: white;
  font-size: 1em;

Answer 1

Bootstrap还具有一个名为array.map { |x| [:name, :number].zip(x.sub(',', ' ').split(',')).to_h } # => [{:name=>"John Doe", :number=>11222019}, {:name=>"Mark King", :number=>11232019}, {:name=>"Angle Darma", :number=>11242019}]的类，该类的样式覆盖了您的样式。

因此将div类从row重命名为row1以查看效果。

也更改css文件中的类名。

row

Answer 2

您使用引导程序，因此请使用引导程序类来制作此flexbox：

html,
body {
  height: 100%;
  padding: 0px;
  width: 100%;
}

body {
  margin: 0;
  padding: 0px;
}

.wrap{
  border: 1px solid blue;
}


.flex-item {
  background-color: tomato;
  padding: 0px;
  width: 20px;
  height: 20px;
  margin: 10px;
  line-height: 20px;
  color: white;
  font-size: 1em;
  font-weight: bold;
  text-align: center;
}

        <div class="flex-item">1</div>
        <div class="flex-item">2</div>
        <div class="flex-item">3</div>
        <div class="flex-item">4</div>
      </div>
      <div class="col-xs-6 wrap">
