问题描述
假设您有一个Div（ id =toolbar），并且在该工具栏中有一个Div（ id =ButtonHolder），其中包含2个按钮。如果你把 #ButtonHolder 浮动到右边，并且没有设置一个明确的宽度，是kosher吗？
Say you have a Div (id="toolbar"), and inside that toolbar you have a Div (id="ButtonHolder") that contains 2 buttons. If you float the #ButtonHolder to the right and don't set an explicit width on it, is that kosher?
我读过堆栈溢出，你应该总是设置浮动元素的宽度。按钮文本可能会改变，从保存到应用，我不想每次都调整 #ButtonHolder 的宽度。
I've read on stack overflow that you should always set a width on a floated element. The buttons text might change, from save to apply, and I don't want to have to adjust #ButtonHolder's width every time.
我想到将 #ButtonHolder 的宽度设置为 auto 默认情况下，似乎没有必要将其宽度设置为自动。我担心浏览器可能不会总是浮动 #ButtonHolder 我认为应该的方式。
I thought about setting #ButtonHolder's width to auto, but the browser does that by default so it seems unnecessary to set it's width to auto. I'm worried the browser might not always float #ButtonHolder the way I think it should.
推荐答案
float 和位置通常带有成本。您应该尝试首先找到其他方法在布局中定位元素。您应该考虑其他选项，如 margin ， padding ， display：inline-block; ， text-align ...等。
float and position usually come with a cost. You should try to first find other ways to position elements within your layout. You can should consider other options such as margin, padding, display: inline-block;, text-align ... etc.

回答您的问题问题直接。浮动的设置宽度不是写在石头上，但不这样做，通常意味着以后的麻烦。至少在我个人的角度来看。
To answer your question directly. Setting width for floats is not written on stone but not doing so, usually means trouble later. At least in my personal point of view.
