如何使 div 块响应？

Question

我有以下代码，在笔记本电脑和台式机等大屏幕设备上连续列出了 5 个步骤，我想让相同的代码对移动设备和平板电脑做出响应，但在过去 3 天里我无法让它工作.

我已经尝试过媒体查询，但它们似乎没有奏效。如何更改代码以使其具有响应性？

.row-equal-height {
    display: -webkit-box;
    display: -webkit-flex;
    display: -ms-flexbox;
    display: flex;
}
.p_column {
    background: #fff;
    color: #000;
    font-size: 22px;
    font-weight: 500;
    margin: 5px 15px 0;
    padding: 30px 15px;
    border: solid 1px #d4d4d4;
    box-shadow: 0px 0px 20px 1px rgba(0, 0, 0, 0.08);
    border-radius: 2px;
    position: relative;
    -webkit-transition: 0.4s;
    -o-transition: 0.4s;
    transition: 0.4s;
    width: 100%;
}
.p_column:first-child {
    background: #c81f56;
    color: #fff;
    border: solid 1px #c81f56;
}
/*Code for arrow*/

.p_column:before,
.p_column:after {
    content: "";
    position: absolute;
    width: 0;
    height: 0;

/* Stroke */

.p_column:before {
    right: -30px;
    border-left-color: #d4d4d4;

/* Fill */

.p_column:after {

         </div>
      </div>

我希望这些块在宽屏幕上保持 5 个一行，在中等屏幕上每行 2 个（平板电脑保持水平模式），在小屏幕设备上每行 1 个。

请将此代码添加到您的 css 中以进行响应。

@media screen and (max-width: 1024px) {

    .row-equal-height {
        flex-wrap: wrap;
    }

    .p_column {
        width: 25%;
        margin: 5px 2% 0;
    }

}

@media screen and (max-width: 767px) {

    .p_column {
        width: 100%;
    }

}
