firefox absolute positioning problem
提问by AlexBrand
I am having trouble rendering this correctly in firefox. It renders nicely in chrome and in safari.
我在 Firefox 中无法正确呈现它。它在 chrome 和 safari 中呈现得很好。
<div style="" id="login_inline">
<form accept-charset="utf-8" action="/users/login" method="post" id="UserLoginForm">
<div style="display:none;">
<input type="hidden" value="POST" name="_method">
</div>
<input type="text" id="UserDummyEmail" tabindex="1" value="Email" name="data[User][dummyEmail]" style="display: block;">
<input type="text" id="UserDummyPassword" tabindex="2" value="Password" name="data[User][dummyPassword]" style="display: block;">
<input type="text" id="UserEmail" maxlength="255" tabindex="3" name="data[User][email]">
<input type="password" id="UserPassword" tabindex="4" name="data[User][password]">

By positioning absolute you become dependent on correct width of the input elements. This is difficult to do cross-browser because browsers tend to use custom or native elements that don't style consistently. You're better off with an inline-block or floated layout that handles inconsistent width.
通过定位绝对值，您将依赖于输入元素的正确宽度。这很难跨浏览器进行，因为浏览器倾向于使用样式不一致的自定义或本机元素。您最好使用处理不一致宽度的内联块或浮动布局。
If you really have to do it that way there are some hacks using css3 box-sizingproperty and/or manually tuning properties like line-height and font size and padding to get all browsers to agree on input sizing but that's harder than it sounds.
如果您真的必须这样做，那么有一些技巧可以使用 css3box-sizing属性和/或手动调整属性（如行高、字体大小和填充）来让所有浏览器就输入大小达成一致，但这比听起来要难。
This question has some info on box-sizingand using percentage/auto width to get consistency: input with display:block is not a block, why not?
这个问题有一些关于box-sizing和使用百分比/自动宽度来获得一致性的信息：输入显示：块不是块，为什么不呢？
EDIT: Based on your comment above you may need to set up some div wrappers to set the size/position of both the hidden and visible elements and then use percentage widths and box-sizingas explained.
编辑：根据您上面的评论，您可能需要设置一些 div 包装器来设置隐藏和可见元素的大小/位置，然后使用百分比宽度和box-sizing解释。
<div class="input_wrapper" style="width:100px;position:relative">
<input style="width:100%;box-sizing:border-box;position:absolute">
<div class="fake_input" style="width:100%;position:absolute">
</div>
The key to it all is that box-sizing:border-boxis less susceptible to browser differences in padding and border calculations on form inputs.
这一切的关键是box-sizing:border-box在表单输入的填充和边框计算方面不太容易受到浏览器差异的影响。

I found it that usually it is good to put a font-size on input fields, this will make the size of them (more) consistent
我发现通常最好在输入字段上设置字体大小，这将使它们的大小（更）一致
