目前它在较小的显示器上按预期工作，但在较大的显示器上，两行位于不同的行上。当我试图让它们在同一条线上时，它会破坏它在较小的显示器上正常工作

我添加了样式并且我的问题包含更多代码，因此这是添加更多文本以便发布。谢谢

Answer 1

这些列在大屏幕中并排显示，在小屏幕中在彼此之上。

您的 HTML/Bootstrap 中存在一些错误，最值得注意的是您试图在一行中包含超过 12 个 col 单位。

解决方法如下:

CSS:

.column_title {
    border: 2px solid rgba(0,0,0,0.1);
    padding: .3em .8em;
    margin-top: 2em;
    margin-bottom: 2em;
    position: relative;
    text-transform: uppercase;
    font-size: 1.3em;
    color: #555;
    font-weight: 600;
    z-index: 1;
    text-align: center;
    float: left;
    height: 50px;
}

.column_title:before {
    content: '';
    position: absolute;
    top: 50%;
    right: 100%;
    border-bottom: 2px solid;
    width: 40%;
    margin: 0 20px;
    color: rgba(0,0,0,0.1);
}

.column_title:after {
    content: '';
    position: absolute;
    top: 50%;
    left: 100%;
    border-bottom: 2px solid;
    width: 40%;
    margin: 0 20px;
    color: rgba(0,0,0,0.1);
}

.column_text {
    float:left;
    clear:left;
}

HTML:

<div class="container">
    <div class="row">
        <div class="col-lg-6">
            <div class="column_title">What we offer</div>
            <div class="column_text">Blah 1</div>
        </div>
        <div class="col-lg-6">
            <div class="column_title">Our benefits</div>
            <div class="column_text">Blah 2</div>
        </div>
    </div>
</div>

祝你好运，让我知道结果如何!
