Simulate Pseudo CSS Classes
:hover
or :active
can be tricky because you can’t always use your mouse. In DevTools, you can easily simulate these states without any hassle. Simply inspect the element and click the :hov button to enable the desired pseudo-class. 
Select Elements with pointer-events:none
pointer-events:none
CSS property. 

Setting Event Breakpoints
When dealing with events like mouseover
and mouseleave
, you can set breakpoints in the Debugger tab of DevTools to pause your code at the exact moment an event is triggered.
For example, if you have a dropdown menu that is created on mouseover
and deleted on mouseleave
, setting a breakpoint on the mouseover
event allows yout to work on your menu without being bothered.
The advantage here is that even if you leave the hoverable item, the menu won’t hide immediately because the browser pauses the execution. You can resume the code by clicking the Play button in the Debugger when you’re ready to continue.
Zoom the DevTools UI
If you find the DevTools interface too small, you can zoom in or out. Click inside the DevTools and use Ctrl
+ +
to zoom in or Ctrl
+ -
to zoom out and Ctrl
+ 0
to reset (use Cmd
on a Mac).
