如何在引导程序中的div内部居中

标签： jquery html css bootstrap-4

我创建了一些卡片，其中文本位于this:等图标旁边的行内居中

现在很久以后，我被告知我必须将引导程序导入到项目中并重新设计所有内容，但是通过导入bs，它已使所有卡的对齐方式脱离了。现在，我正在展示它们并展示内容的内容，但这似乎并没有太大帮助。 here is a codepen snippet of what I have. ` 

#slider,
.wrap,
.slide-content {
  margin: 0;
  padding: 0;
  font-family: Arial, Helvetica, sans-serif;
  overflow-x: hidden;
  height: 100%;
}

.wrap {
  position: relative;
  grid-row-start: 1;
  grid-row-end: 5;
}

.slide {
  background-size: cover;
  background-position: center;
  background-repeat: no-repeat;
  height: 100%;
}

.slide1 {
  background-image: url("pics/purple_jerseys.jpg");
}
.slide2 {
  background-image: url("pics/soccer_boys.jpg");
}
.slide3 {
  background-image: url("pics/soccer girl.jpg");
}

.slide-content {
  display: flex;
  flex-direction: column;
  justify-content: center;
  align-items: center;
}

.slide-content span {
  font-size: 4rem;
  color: #fff;
  position: absolute;
  top: 8px;
  right: 45px;
  left: 8px;
  text-shadow: 2px 2px 4px #000000;
}

.arrow {
  cursor: pointer;
  position: absolute;
  top: 50%;
  margin-top: -35px;
  width: 0;
  height: 0;
  border-style: solid;
}

#arrow-left {
  border-width: 30px 40px 30px 0;
  border-color: transparent #fff transparent transparent;
  left: 0;
  margin-left: 30px;
}

#arrow-right {
  border-width: 30px 0 30px 40px;
  border-color: transparent transparent transparent #fff;
  right: 0;
  margin-right: 30px;
}

.container {
  display: grid;
  grid-template-columns: 2fr 1fr;
  grid-template-rows: repeat(5, 20%);
  grid-gap: 1em;

  margin-top: 0px;
}

.ref-icon {
  height: 23px;
  color: #FFBB3F;
  margin-top: 4px;
}

.card p {
  width: 80%;
}

.card img {
  margin: auto;
}

.card * {
  margin-top: 0;
}

.socials {

`非常简单，我只需要帮助正确对齐内容即可。

你可以试试这个吗.. 

 <div class="card">
         <h1>Spring Registration Open</h1>
         <div class="flx">
            <div> 
               <i class="fa fa-pencil-square-o fa-3x" aria-hidden="true"></i>
            </div>
            <div>
               <p>Core registration for Spring 2019 is now open. <a href="#">Register here</a></p>
            </div>
         </div>
      </div>

和CSS 

.flx {
    display: flex;
    align-items: center;
}

.flx>div {
    padding: 1rem;
}

使用Grid系统的Bootstrap，在这里我们定义了两列，第一列为col-lg-2，第二列为col-lg-10：

enter image description here 

  <div class='row'>
      <h1>CORE WINTER SCHEDULE</h1>
       <div class='col-lg-2'>
           <i class="fa fa-list-ol fa-3x" aria-hidden="true"></i>
       </div>
       <div class='col-lg-10'>
           <p>Lorem Ipsum</p>
       </div>
  </div>
