Boostrap / CSS / Javascript / PHP：如何将列表显示为lg屏幕的3列和sm屏幕的1列

问题描述 投票：0回答：1

在计算机上，我的列表如下：enter image description here

但是在电话上，它仅显示第一列，并且不会以1列列表的形式继续显示该列表。

我正在使用Bootstrap，代码如下：

 <section>
        <div class="container">
            <div class="row align-items-start">
                <div class="col-sm-12 col-md-4">
                    <div class="p-3">

                        <b>Statewide Texas Sites</b><br />
                        <a href="https://www.touringtexas.com/" target="_top">Touring Texas</a>
                        <br />
                        <a href="https://www.texas-lakes.net/" target="_top">Texas Lakes</a>
                        <br />

                    </div>
                </div>

                <div class="col-sm-12 col-md-4 col-md-push-4">
                    <div class="p-3">

                        <b>Texas Tourist Areas</b><br />
                        <a href="https://www.highlandlakes.com/" target="_top">Highland Lakes</a>
                        <br />
                        <a href="https://www.hill-country.net/" target="_top">Hill Country Network</a>
                        <br />

                    </div>
                </div>


                <div class="col-sm-12 col-md-4 col-md-push-4">
                    <div class="p-3">

                        <b>Texas Lakes</b><br />

                        <br />
                        <a href="https://www.lake-bridgeport.com/" target="_top">Lake Bridgeport</a>
                        <br />

                    </div>
                </div>
            </div>
        </div>
    </section>

应该工作正常，看起来您的设置有问题，首先我可以认为是视口，请检查您的头中是否有<meta name="viewport" content="width=device-width, initial-scale=1, shrink-to-fit=no">。

请参阅在手机和办公桌上工作的示例。

<html lang="en">
