我想让蓝绿色和绿色 div 位于红色 div 的中心。我试过 margin:0 自动、 float 、文本对齐,所有这些都不起作用。

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

如何使这些 div 水平和垂直居中?

非常感谢任何帮助,谢谢

最佳答案

使用flex定位。

/* 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 {

-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>
