Hi, it seems you refer to WPBakery Page Builder (previously known as Visual Composer Page Builder). If you update the plugin, you will see the changes. But in both cases, you can’t specify background image size – this must be aligned before uploaded. What you can change is background-position and background-size in terms of cover, repeat, no-repeat, etc.

What is the way to set the background image size like: background-size: 128px in the Visual Composer? I didn’t find any option like that here- http://prntscr.com/reprv6 But it’s important for me.

Apparently I’m working like this way:
#hero_sect_left .vc_custom_1583909467830, #hero_sect_left .vc_column-inner{
background-size: 128px !important;
}
But it’s not a convenient way.

How to I can do that with VC?

Thanks.
