css – Yii 2应用程序中缺少Bootstrap 3标注

<div class="bs-callout bs-callout-info">
    <h4>Use protocol</h4>
    Avoid links without <code>http://www.</code> or <code>https://www.</code> in the beginning.
</div>

标注在他们的文档中使用,但它不包含在主CSS中. Yii 2附带最新版本的Bootstrap(当前时刻为3.3.4),所以这不是原因.

你必须自己编写适当的CSS样式.根据this article你需要添加这个：

.bs-callout {
    padding: 20px;
    margin: 20px 0;
    border: 1px solid #eee;
    border-left-width: 5px;
    border-radius: 3px;
}
.bs-callout h4 {
    margin-top: 0;
    margin-bottom: 5px;
}
.bs-callout p:last-child {
    margin-bottom: 0;
}
.bs-callout code {
    border-radius: 3px;
}
.bs-callout+.bs-callout {
    margin-top: -5px;
}
.bs-callout-default {
    border-left-color: #777;
}
.bs-callout-default h4 {
    color: #777;
}
.bs-callout-priMary {
    border-left-color: #428bca;
}
.bs-callout-priMary h4 {
    color: #428bca;
}
.bs-callout-success {
    border-left-color: #5cb85c;
}
.bs-callout-success h4 {
    color: #5cb85c;
}
.bs-callout-danger {
    border-left-color: #d9534f;
}
.bs-callout-danger h4 {
    color: #d9534f;
}
.bs-callout-warning {
    border-left-color: #f0ad4e;
}
.bs-callout-warning h4 {
    color: #f0ad4e;
}
.bs-callout-info {
    border-left-color: #5bc0de;
}
.bs-callout-info h4 {
    color: #5bc0de;
}

随你进入CSS样式.

然后你可以使用这样的标注：

<div class="bs-callout bs-callout-success">
  <h4>success Callout</h4>
  This is a success callout.
</div>
