为什么3位数的十六进制颜色代码值在Internet EXPLORER中的解释不同？ [英] Why are 3-digit hex color code values interpreted differently in Internet EXPLORER?

问题描述

Internet Explorer如何解释它们，以及根据哪种指南或一套标准？

How exactly is Internet Explorer interpreting them, and under which guideline or set of standards?

例如：

#FFF

在Google Chrome中似乎为白色，而在Internet Explorer （我在8和9上测试它）显示为黑色。

is seem as the color white in Google Chrome, for instance, whereas in Internet Explorer (I tested it on 8 and 9) it appears as black.

我用来测试的代码如下：

I code I used to test this was as follows:

< body bgcolor =＃ffffff>与< body bgcolor =＃fff>

（我知道 bgcolor 已废弃，它只是方便我手头完成的）。

(I am aware that bgcolor is deprecated, it was just convenient for what I was accomplishing at hand).

我也知道这是一个错误，它可以通过在hexcode中添加几位数字（all-in-all 6）可以很容易地修正，但是我只是想看到科学背后的原因，如果它有一个解释。

I am also aware that this is a bug, and that it can be easily fixed by appending a few digits (all-in-all 6) to the hexcode, but I am just interested in seeing the science behind why it occurs, if there is an explanation for it.

推荐答案

我能够在IE11中重新创建它。如你所知，它是一个不推荐使用的属性。我假设你的网页&浏览器试图将代码解释为HTML5，并且有一个错误在他们的优雅退化来处理这个。

I was able to recreate it in IE11 as well. As you know, it is a deprecated attribute. I assume your webpage & the browser are trying to interpret the code as HTML5 and there is a bug in their graceful degradation to handle this. So it just breaks.

正如@Aaron Vanston指出，使用内联样式或CSS，你仍然可以使用速记十六进制来应用颜色。

As @Aaron Vanston points out, using inline style or CSS, you can still use the shorthand hex to apply a color.

我甚至不会浪费我的时间写出 bgcolor 作为属性。如果我遇到了我正在处理的东西，我会删除它赞成

I wouldn't even waste my time writing out bgcolor as an attribute. If I came across it in something I was working on, I'd remove it in favor of

style="background-color: #fff"

或CSS替代

body {
    background-color: "#fff";
}
