如何在引导列之间添加边距而不换行[重复]

我的布局目前看起来像这样

在中心列中，我想在每个之间添加一个小边距Server分区但是，如果我向 CSS 添加边距，它最终会换行并看起来像这样

<div class="row info-panel">
    <div class="col-md-4 server-action-menu" id="server_1">
        <div>
            Server 1
        </div>
    </div>
    <div class="col-md-4 server-action-menu" id="server_2">
        <div>
            Server 2
        </div>
    </div>
    <div class="col-md-4 server-action-menu" id="server_3">
        <div>
            Server 3
        </div>
    </div>
    <div class="col-md-4 server-action-menu" id="server_4">
        <div>
            Server 4
        </div>
    </div>
    <div class="col-md-4 server-action-menu" id="server_5">
        <div>
            Server 5
        </div>
    </div>
    <div class="col-md-4 server-action-menu" id="server_6">
        <div>
            Server 6
        </div>
    </div>
    <div class="col-md-4 server-action-menu" id="server_7">
        <div>
            Server 7
        </div>
    </div>
</div>

还有CSS

.server-action-menu {
    background-color: transparent;
    background-image: linear-gradient(to bottom, rgba(30, 87, 153, 0.2) 0%, rgba(125, 185, 232, 0) 100%);
    background-repeat: repeat;
    border-radius:10px;
}

.info-panel {
    padding: 4px;
}

我尝试通过这样做来添加边距

.info-panel  > div {
    margin: 4px;    
}

如何为 DIV 添加边距，以便它们不会在右侧留下太多空间？

您应该在内部容器上使用填充，而不是使用边距。尝试这个！

HTML

<div class="row info-panel">
    <div class="col-md-4" id="server_1">
       <div class="server-action-menu">
           Server 1
       </div>
   </div>
</div>

CSS

.server-action-menu {
    background-color: transparent;
    background-image: linear-gradient(to bottom, rgba(30, 87, 153, 0.2) 0%, rgba(125, 185, 232, 0) 100%);
    background-repeat: repeat;
    border-radius:10px;
    padding: 5px;
}
