有没有办法在Safari Web检查器中获取伪元素的计算量度？
[英]Is there way to get computed metrics of pseudo elements in Safari web inspector?
问题描述
I am primarily using Chrome developer tools for debugging html/css/js, but now I needed to debug different rendering of pseudo element in Chrome vs Safari. 
我主要是使用Chrome开发人员工具来调试html / css / js，但现在我需要在Chrome与Safari中调试伪元素的不同呈现方式。
I could not find a way to get computed metrics (or any computed css properties) of :before pseudo element in Safari. 我找不到一种方法来获取Safari中伪元素前的计算指标（或任何计算后的CSS属性）。

You're not able to view the pseudo tag directly within the DOM inspection window but you can view the pseudo styles within the style inspector window in the right column. 您无法直接在DOM检查窗口中查看伪标记，但可以在右侧列的样式检查器窗口中查看伪样式。
