Horizontally align div without float
提问by Azincourt
I want to know if there exists an elegantway to horizontally align 3 divswithout usingfloatcss property.
我想知道是否有一种优雅的方法可以在divs不使用floatcss 属性的情况下水平对齐 3 。
HTML:
HTML:
<div id="parent">
<div id="first">Left</div>
<div id="second">Middle</div>
<div id="third">Right</div>
</div>
I ask this question because the parent divhas not floatproperty and adding floatto children cause problems on page resizing.
我问这个问题是因为父级div没有float属性,并且添加float到子级会导致页面调整大小出现问题。

You can use display:inline-blockor display:table-cellwith the inner content.
您可以使用display:inline-block或display:table-cell与内部内容一起使用。
- Flex layout(See also T J's answer):
- Flex 布局(另见TJ 的回答):
#parent{ display:flex; justify-content: space-between; }
- Table layout:
- 表布局:
#parent{ display:table; width:100%; }
#parent div{ display:table-cell; }
#first{ text-align:left; }
#second{ text-align:center; }
#third{ text-align:right; }
- Inline-block layout :
- 内联块布局:
#parent{ width:100%; white-space:nowrap; }
#parent div{ display:inline-block; width:33.3%;}
#first{ text-align:left; }
#second{ text-align:center; }
#third{ text-align:right; }

Adding to notulysses's answer, If ancient browser support is not an issue, you can use css3 Flexible_boxes.
添加到notulysses的答案,如果古老的浏览器支持不是问题,您可以使用 css3 Flexible_boxes。
By applying display:flexthe child divs will be aligned horizontally (by default)
通过应用display:flex子 div 将水平对齐(默认情况下)
#parent{
display:flex;
justify-content:space-around;
}

Instead of finding a workaround for floating, you could also use the following fix for your "resizing problems" (at least what I think it is caused by):
除了找到浮动的解决方法之外,您还可以使用以下修复程序来解决“调整大小问题”(至少我认为是由什么引起的):
After using floats, you should always clear your floats. You can do this by adding an extra <div>with a class.
使用浮动后,您应该始终清除浮动。您可以通过添加一个额外<div>的类来做到这一点。
<div id="parent">
<div id="first">Left</div>
<div id="second">Middle</div>
<div id="third">Right</div>
<div class="clear"></div>
</div>
In CSS:
在 CSS 中:
.clear{
clear: both;
}
