如何显示3个div之间的空格并将它们保持在同一行上

Question

我有以下HTML，使用bootstrap语法来显示3个div：

​

.main-background {
  background-color: white;
  padding-top: 40px;
  padding-right: 20px;
  padding-bottom: 40px;
  padding-left: 20px;
}

.main-Image {
  display: flex;
  padding-bottom: 40px;
  -webkit-box-pack: center;
  justify-content: center;
  -webkit-box-align: center;
  align-items: center;
  background-color: white;
  box-sizing: border-box;
}

.main-h3 {
  align-items: center;
  background-color: #fff;
  font-family: Lora, sans-serif;
  color: #162b3b;
  font-size: 24px;
  line-height: 1.5em;
  font-weight: 400;
  text-align: center;
  display: flex;
  padding: 10px 40px 40px;
  -webkit-box-align: center;
  box-sizing: border-box;
}

.main-footer {
  font-family: 'Source Sans Pro', sans-serif;
  color: #162b3b;
  font-size: 18px;
  line-height: 24px;
  text-align: center;
  box-sizing: border-box;
}

<div class="row ">
  <div class="col-xl-4 main-background">
    <div class="main-Image">
      <img src="~/img/How_It_Works_Personalized-1.jpg" loading="lazy" sizes="(max-width: 479px) 93vw, 250px" width="250" />

    </div>

    <div class="main-h3">
      1. Personalized Recommendations

    </div>


    <div class="main-footer">
      Receive practice-specific, data-driven recommendations and care plans
    </div>
  </div>
  <div class="col-xl-4 main-background">
    <div class="main-Image">
      <img src="~/img/How_It_Works_Personalized-1.jpg" loading="lazy" sizes="(max-width: 479px) 93vw, 250px" width="250" />

    </div>

    <div class="main-h3">
      1. Personalized Recommendations

    </div>


    <div class="main-footer">
      Receive practice-specific, data-driven recommendations and care plans
    </div>
  </div>
  <div class="col-xl-4 main-background">
    <div class="main-Image">
      <img src="~/img/How_It_Works_Personalized-1.jpg" loading="lazy" sizes="(max-width: 479px) 93vw, 250px" width="250" />

    </div>

    <div class="main-h3">
      1. Personalized Recommendations

    </div>


    <div class="main-footer">
      Receive practice-specific, data-driven recommendations and care plans
    </div>
  </div>

</div>

目前，这3个div将显示为彼此对齐，如下所示：

​

​

那么，如何才能在3个div之间添加一些水平空间，而不会导致最后一个div转到单独的行呢？现在，如果我尝试将margin-left和margin-right添加到中间的div，这将导致最后一个div移到新行！

你可以使用这些代码，它会满足你的需求。使用flex-wrap:nowrap !important;

如果你使用它们，它将不会达到底线。

​

.row {
  display:flex;
  flex-wrap:nowrap !important;
  background-color:red;
  justify-content:safe center;
}

.main-background {
  background-color:#ddd;
  padding-top: 40px;
  padding-right: 20px;
  padding-bottom: 40px;
  padding-left: 20px;
  margin-left:15px;
  margin-right:15px;
  width:auto;
}

.main-Image {
  display: flex;
  padding-bottom: 40px;
  -webkit-box-pack: center;
  justify-content: center;
  -webkit-box-align: center;
  align-items: center;
  background-color: white;
  box-sizing: border-box;
}

.main-h3 {
  align-items: center;
  background-color: #fff;
  font-family: Lora, sans-serif;
  color: #162b3b;
  font-size: 24px;
  line-height: 1.5em;
  font-weight: 400;
  text-align: center;
  display: flex;
  padding: 10px 40px 40px;
  -webkit-box-align: center;
  box-sizing: border-box;
  justify-content:center;
}

.main-footer {
  font-family: 'Source Sans Pro', sans-serif;
  color: #162b3b;
  font-size: 18px;
  line-height: 24px;
  text-align: center;
  box-sizing: border-box;
}

这使得移动设备的底线

@media (max-width:768px) {
.row {
  flex-wrap:wrap !important;
