如何在父 div 中水平居中

如何用 CSSdiv水平地置于其父 div内?

<div id='parent' style='width: 100%;'>
<div id='child' style='width: 50px; height: 100px;'>Text</div>
</div>

I am assuming the parent div has no width or a wide width, and the child div has a smaller width. The following will set the margin for the top and bottom to zero, and the sides to automatically fit. This centers the div.

div#child {
margin: 0 auto;
}
<div id='parent' style='width: 100%;text-align:center;'>
<div id='child' style='width:50px; height:100px;margin:0px auto;'>Text</div>
</div>

您可以使用左右边距的“ auto”值,让浏览器在内部 div 的两边平均分配可用空间:

<div id='parent' style='width: 100%;'>
<div id='child' style='width: 50px; height: 100px; margin-left: auto; margin-right: auto'>Text</div>
</div>

只是出于兴趣,如果你想要居中两个或更多的 div (所以他们并排在中心) ,然后这里是如何做到这一点:

<div style="text-align:center;">
<div style="border:1px solid #000; display:inline-block;">Div 1</div>
<div style="border:1px solid red; display:inline-block;">Div 2</div>
</div>
.parent-container {
display: flex;
justify-content: center;
align-items: center;
}


.child-canvas {
flex-shrink: 0;
}
