This is my ElvUI profile as DPS (melee and ranged). It's simple, sober and leaves a maximum of space in the middle for a clear view in combats.
For this profile to work entirely, you will need ElvUI addons :
AddOnSkins : https://www.tukui.org/addons.php?id=3
BC Solutions : https://www.tukui.org/addons.php?id=218

I play with Details! so windows in the right chat panel are set so. You can change them via AddOnSkins
