显示:flex - 在 Firefox 21 中不起作用 [英] display: flex - not working in firefox 21

问题描述

根据这篇文章，display:flex 属性在 firefox 21 中应该可以在没有任何前缀的情况下工作.但是，即使我在值之前使用 -moz-，它也不会被 HTML 解析器识别.

According to this article, the display:flex property should work without any prefix in firefox 21. But, even if I use -moz- before the value, it is not being recognized by the HTML parser.

我最近尝试卸载 firefox 20 并重新安装 firefox 21，希望它能正常工作，但它没有.

I tried uninstalling firefox 20 and reinstalling firefox 21 recently hoping it would work, but it doesn't.

在使用 Web 开发人员工具时，我可以看到以下警告和错误:

When using the web developer tools, I can see the following warnings and errors:

这些不是全部错误，而是一些错误.谁能指出问题是什么?

Those are not all the errors but some. Can anyone point out what the problem is?

提前致谢！

推荐答案

display: flex 目前仅在 Firefox 中的运行时标志后面受支持.

display: flex is currently only supported behind a runtime flag in Firefox.

要启用它，请在 url 字段中输入 about:config，搜索 flexbox，并将其设置为 true.

To enable it, enter about:config in the url field, search for flexbox, and set it to true.

它在 Firefox Nightly 中默认启用，因为它是一个不稳定的版本.

It is enabled by default in Firefox Nightly, as it is a non-stable version.

它会在 Firefox 22 中默认启用，前提是该功能已准备好发布.

It is due to be enabled by default in Firefox 22, providing the feature is ready to ship.
