Question

您可以从以下代码中获取 W3schools.com为博客博客帖子定制了它。

＆＃13;

<style>
/*----------Price Box--------------*/

.pricecolumns {
    float: left;
    width: 33.3%;
    padding: 8px;
}

.price {
    list-style-type: none;
    border: 1px solid #eee;
    margin: 0;
    padding: 0;
    -webkit-transition: 0.3s;
    transition: 0.3s;
}

.price:hover {
    box-shadow: 0 8px 12px 0 rgba(0,0,0,0.2)
}

.price .priceheader {
    background-color: #2CB8DA;
    color: white;
    font-size: 25px;
}

.price li {
    border-bottom: 1px solid #eee;
    padding: 20px;
    text-align: center;
}

.price .grey {
    background-color: #FFFFEF;
    font-size: 20px;
}

.pricebutton {
    background-color: #FBA614;
    border: none;
    color: white;
    padding: 10px 25px;
    text-align: center;
    text-decoration: none;
    font-size: 18px;
}
</style>

＆＃13;

<body>
<div class="pricecolumns">
  <ul class="price">
    <li class="priceheader">Rent</li>
    <li class="grey">$ 18.99 / Month</li>
    <li>Test The Product on Live Market</li>
    <li class="grey"><a href="#" class="pricebutton">Rent</a></li>
  </ul>
</div>

<div class="pricecolumns">
  <ul class="price">
    <li class="priceheader" style="background-color:#4CAF50">Buy</li>
    <li class="grey">$ 27.99 Life Time</li>
    <li>Buy Forever License</li>
    <li class="grey"><a href="#" class="pricebutton">Buy Now!</a></li>
  </ul>
</div>
</body>

＆＃13;

但问题是。街区一个接一个地展示。与网站上显示的2列不同。

我无法添加以下代码（正如教程建议的那样），因为这个代码让博客下拉菜单看起来很奇怪。

＆＃13;

* {
    box-sizing: border-box;
}

＆＃13;

Answer 1

你的CSS有问题。 您在css中使用了错误的css选择器，这是一个错字。

更改此内容

.pricecolumns {
    float: left;
    width: 33.3%;
    padding: 8px;
}

到此 -

.price_columns {
    float: left;
    width: 33.3%;
    padding: 8px;
}

以下是2个comlumns和3个列的认可 -

2列 -

/*----------Price Box--------------*/

.price_columns {
    float: left;
    width: 33.3%;
    padding: 8px;
}

.price {
    list-style-type: none;
    border: 1px solid #eee;
    margin: 0;
    padding: 0;
    -webkit-transition: 0.3s;
    transition: 0.3s;
}

.price:hover {
    box-shadow: 0 8px 12px 0 rgba(0,0,0,0.2)
}

.price .priceheader {
    background-color: #2CB8DA;
    color: white;
    font-size: 25px;
}

.price li {
    border-bottom: 1px solid #eee;
    padding: 20px;
    text-align: center;
}

.price .grey {
    background-color: #FFFFEF;
    font-size: 20px;
}

.pricebutton {
    background-color: #FBA614;
    border: none;
    color: white;
    padding: 10px 25px;
    text-align: center;
    text-decoration: none;
    font-size: 18px;
}

@media only screen and (max-width: 520px) {
    .pricecolumns {
        width: 100%;
    }
}

<body>
<div class="price_columns">
  <ul class="price">
    <li class="priceheader">Rent</li>
    <li class="grey">$ 18.99 / Month</li>
    <li>Test The Product on Live Market</li>
    <li class="grey"><a href="#" class="pricebutton">Rent</a></li>
  </ul>
</div>

<div class="price_columns">
  <ul class="price">
    <li class="priceheader" style="background-color:#4CAF50">Buy</li>
    <li class="grey">$ 27.99 Life Time</li>
    <li>Buy Forever License</li>
    <li class="grey"><a href="#" class="pricebutton">Buy Now!</a></li>
  </ul>
</div>
</body>

Box-Sizing仅适用于此特定部分：

/*----------Price Box--------------*/

.price_columns {
  float: left;
  width: 33.3%;
  padding: 8px;
  box-sizing: border-box;
  -moz-box-sizing: border-box;
  -moz-box-sizing: border-box;
}

.price {
  list-style-type: none;
  border: 1px solid #eee;
  margin: 0;
  padding: 0;
  -webkit-transition: 0.3s;
  transition: 0.3s;
}

.price:hover {
  box-shadow: 0 8px 12px 0 rgba(0, 0, 0, 0.2)
}

.price .priceheader {
  background-color: #2CB8DA;
  color: white;
  font-size: 25px;
}

.price li {
  border-bottom: 1px solid #eee;
  padding: 20px;
  text-align: center;
}

.price .grey {
  background-color: #FFFFEF;
  font-size: 20px;
}

.pricebutton {
  background-color: #FBA614;
  border: none;
  color: white;
  padding: 10px 25px;
  text-align: center;
  text-decoration: none;
  font-size: 18px;
}

@media only screen and (max-width: 520px) {
  .pricecolumns {
    width: 100%;
  }
}

<body>
  <div class="price_columns">
    <ul class="price">
      <li class="priceheader">Rent</li>
      <li class="grey">$ 18.99 / Month</li>

      <li class="grey"><a href="#" class="pricebutton">Rent</a></li>
    </ul>
  </div>

  <div class="price_columns">
    <ul class="price">
      <li class="priceheader" style="background-color:#4CAF50">Buy</li>
      <li class="grey">$ 27.99 Life Time</li>

Answer 2

<div class="price_columns">是你的错误，因为在CSS中你没有下划线的课，你有pricecolumns

CSS在定价表中添加列
