CSS最大宽度在IE8 [英] CSS Max-Width in IE8

问题描述

对于我的输入，可以有 classname =half或half.not-placeholder-value，Firebug显示两个输入有一组，固定宽度 25em 。

For my input, which can either have classname="half" or "half.not-placeholder-value", Firebug shows both inputs to have a set, fixed width of 25em.

input.half, input.half.not-placeholder-value {
    max-width: 25em;
}

然而，根据开发人员工具，IE8似乎没有使用这个特殊的 max-width 属性。我说似乎不使用，因为Firefox的行为不同于IE8相对于这个属性。

Yet, according to Developer Tools, IE8 doesn't seem to use this particular max-width attribute. I say "doesn't seem to use" since Firefox's behavior differs with IE8 with respect to this attribute.

但MDN docs 说IE7支持 max-width 。

But the MDN docs say that IE7 supports max-width. Am I missing something?

推荐答案

这不是IE8的问题，因为IE8 支持max -width属性，但仅在首先给定定义的宽度时。

This is not really an IE8 issue since IE8 does support the max-width attribute but only when given a defined width first.

input.half, input.half.not-placeholder-value {
    width: 100%;
    max-width: 25em;
}
