Hide mesh faces while showing vertices/edges in edit mode (Blender 2.8)

[Update] I've found the answer. For anyone else looking for a similar effect go to the modeling tab -> viewport overlays -> mesh edit mode -> deselect faces
I am in edit mode in the 3D view and my scene looks like the first picture below. I want to hide the faces so I can edit while only seeing the vertices & edges like the wireframe below, but I need to keep the faces as part of the mesh.
If I select the faces and press H to hide them the vertices and edges are hidden too. If I make the mesh a wireframe the faces are removed, not just made invisible.
How can I hide the faces while still showing the vertices and edges?
Do Command h on mac and Ctrl on windows, Linux and Chromebook.

Blender 2.8 video editing video becomes dark

All configurations are default, I have not changed anything, in the old version is correct, under is my screenshot:
This is a screenshot of Blender 2.8:
And this is a screenshot of Blender 2.79:
When I open the new project (created by Blender 2.8) in Blender 2.79, the video is dimmed too.
In Blender 2.80+ go to Context: Render Menu (Menu where cycles or Eevee can be selected), expand Color Management and set View Transform to Standard instead of Filmic. In my case it was set to Filmic by default and the rendered video looked dark gray instead of bright white.

Diamond shapes within Revolution slider

I tried to create diamond shape images into the Slider Revolution like you can see ​here. Unfortunately I cannot figure out how to create diamond images in Slider Revolution.
Actions:
I created custom square shape in Slider Revolution.
I rotated the square shape 45 degrees. So far so good!
I changed background of square with layer CSS:
{background-image: url("../wp-content/uploads/2016/04/SBLi-brand-signs-G-STAR-RAW.jpg");}
Result:
1.. Background image viewed in slider-revolution customizer but not on front-end website.
2. Background image rotated together with the square, how do I rotate back the background or is there a smarter, easier way to create diamond images in Slider Revolution?
I attached a image for better understanding of my diamond image issue :)
