Question

我想让绿松石和绿色的div位于红色div的中心。我试过边距：0自动，浮动，文本对齐，所有这些都不起作用。

turquoise div = header-logo-wrap
green div = header-text-wrap

如何让这些div水平和垂直居中？

非常感谢任何帮助，谢谢

使用flex定位。

@charset "UTF-8";

/* CSS Document */

body {
  background-color: #F6F7C1;
  padding: 0px;
  margin: 0 auto;
  /* aligns content to touch the edge; gets rid of default spacing/margin between edge and content */
}
/* Header */

#header-wrap {
  background: #D6ECFF;
  width: 100%;
  height: auto;
  border-bottom: 3px solid #CCC;
  /* margin:0 auto; needed? */
}
#header-top {
  /* contains logo & title text */
  background: #F00;
  width: 100%;
  height: 200px;
  margin: 0 auto;
  /* aligns centrally */
  display: flex;
  justify-content: center;
  align-items: center;
}
.header-text-wrap {
  width: 452px;
  height: auto;
  background: #0F0;
  text-align: justify;
  float: left;
}
.header-logo-wrap {
  width: 100px;
  height: 100px;
  background: #0CC;
  text-align: justify;
  float: left;
}
#header-bottom {
  /* contains navigation menu */
  background: #00F;
  width: 100%;
  height: 50px;
  margin: 0 auto;
  /* aligns centrally */
  border-top: 3px solid #CCC;
}
/* Fonts */

header {
  font-family: Arial, sans-serif, tahoma, Arial, Cambria;
  -webkit-font-smoothing: antialiased;
  /* subtley makes fonts smoother */
  font-size: 45px;
  text-transform: uppercase;
  line-height: 40px;
}
slogan {
  font-family: courier new, tahoma, Arial, Cambria, serif;
  -webkit-font-smoothing: antialiased;
  /* subtley makes fonts smoother */
  font-size: 20px;
  text-transform: uppercase;
  word-spacing: 10px;
  letter-spacing: 5px;
}

<div id="header-wrap">

  <div id="header-top">
    <div class="header-logo-wrap"></div>

    <div class="header-text-wrap">
      <header>text goes here &amp; more here
      </header>
      <slogan>more text goes here</slogan>
    </div>

  </div>
  <div id="header-bottom"></div>

Answer 2

你需要制作这些div {s} display: inline-block以使它们水平居中，并使display: table-cell包裹容器以使div垂直居中。
