Question

我正在制作my site的子菜单栏。它适用于chrome和firefox，但在safari上它就在那里因为，我可以点击子菜单项，但是没有可见。当有多个子菜单时，我在chrome之前遇到了类似的问题。我通过固定它来固定它并设置顶部和左边。

Het was mijn eerst spel wat ik had gemaakt in Java, ik was begonnen met het maken van de Rubik's Cube in de vakantie in 2016. Het is gemaakt met behulp van JavaFx dit is een interface libarie voor Java. In het spel is een grote fout wat komt door een niet handige manier van id's opslaan. tijdens het maken van dit spel heb ik mijn vaardig heden met java enorm vergroot.

Het spel heb ik gemaakt in Java, in het begin van het project werkte ik samen met iemand maar hij had na paar dagen geen zin er om verder te werken dus toen stond ik er alleen voor. Ik had de server kant uiteindelijk af en was bezig met de client. helaas heb ik het spel niet afgemaakt omdat ik geen insperatie had om het spel af te maken. ik denk als me klasgenoot nog hielp dat het ondertussen speelbaar was.

调试

如果将来发生类似这样的事情，你需要调试它。

所有现代浏览器都具有内置的Web Inspectors /开发人员工具（如果它们对您不够好 - 您可以随时获取Firebug）。

如果网站在X浏览器中看起来不同，您需要做的就是检查看起来不同的元素，然后看看它们应用了哪些CSS规则。这些差异几乎总是与应用的不同规则有关。如果您无法跟踪CSS文件中的现有规则，则很可能会添加JavaScript。

我已经为您的案例记录了一个快速的GIF，请注意从您的链接移除浮动和最小宽度后一切正常（如前所述，Imube）。你实际上并不需要花车，因为inline-block会很好。我一般建议尽可能避免浮动。

为什么不能正常工作

与其他浏览器相比，看起来Safari 解释会忽略display:inline-block（在这种情况下，inline-block应该是什么意思？）。

使用开发工具很容易找到它：
