margin-left: auto and margin-right: auto not working on input
提问by Zaki Aziz
I have an input in a form that I am trying to align in the center. Usually margin-left:autoand margin-right: autofail to respond when display: blockisn't added to the CSS. I have added display: blockto my CSS but still it isn't display as I would like it to.
我有一个表单输入，我试图在中心对齐。通常margin-left:auto并margin-right: auto不能响应时，display: block不加入CSS。我已经添加display: block到我的 CSS 中，但它仍然没有像我希望的那样显示。

In order for margin: 0 auto;to work, in addition to display:blocka widthneeds to be specified.
为了margin: 0 auto;工作，除了display:blockawidth需要被指定。

In my case, it was float: leftthat I forgot about. So, make sure you apply float: noneto your input field.
就我而言，这是float: left我忘记了。因此，请确保您适用float: none于您的输入字段。
You already have display: blockand margin: 0 auto, you just need to set width too.
你已经有了display: blockand margin: 0 auto，你只需要设置宽度。
Example that should work:
应该工作的例子：
input{
width:50% !important;
margin:0 auto !important;
display:block !important;
float:none !important;
}
If that doesn't work try adding !importantto the values or make sure your style is not overwritten by something else.
如果这不起作用，请尝试添加!important值或确保您的样式没有被其他东西覆盖。

You want the three forms together to be aligned in the center? Wrap them in a single div and center that div instead.
您希望三个表格一起在中心对齐吗？将它们包装在一个 div 中，然后将该 div 居中。

in addition to specifying width and display block also check if the float property is set to none.
除了指定宽度和显示块之外，还要检查浮动属性是否设置为无。
