如何在 HTML 中设置盒子居中
在 HTML 中设置盒子居中是常见且有用的任务。有几种方法可以实现这一点,具体取决于要对齐的元素类型以及所需的居中方式。
水平居中
水平居中是指使盒子水平对其父元素居中。有两种常用的方法:
-
text-align: center;
:这会将文本内容水平居中在一个块级元素中。 -
margin: 0 auto;
:这会将块级元素水平居中在父元素中。
例如:
<div style="text-align: center;"> <p>Hello, world!</p> </div>
垂直居中
垂直居中是指使盒子垂直对其父元素居中。有两种常用的方法:
-
vertical-align: middle;
:这会将行内元素(如图像或文本)垂直居中在父元素中。 -
display: flex; align-items: center;
:这会将块级元素垂直居中在父元素中。
例如:
<div style="display: flex; align-items: center;"> <img src="/static/imghwm/default1.png" data-src="image.jpg" class="lazy" style="max-width:90%" alt="How to set the box to be centered in html" > </div>
两个维度居中
要同时水平和垂直居中一个盒子,可以使用 flexbox
,如下所示:
<div style="display: flex; justify-content: center; align-items: center;"> <div>Box</div> </div>
