It's pretty simple, you can refer to Microsoft's design guidelines, or just remember the steps below:
Blur the background, darken the blur layer, tint, apply noise texture
Why did I create this?
First of all, I want some feedback on my UI designs with concept art. And, of course, we know Roblox's webpage is clutter, so, I was thinking, why not try to create concept art that looks less clutter and tends to be much cleaner, perhaps Roblox will take a look at it?
Yes, please! If Roblox turned more application-based (with an actual client on the computer - also allows for more control and possible anti-cheat) and used these designs, then that’d be a big step up!
All of them looks really clean and beautiful. I think the acrylic version looks better for console than the website itself. And the ads can just be on the sides and reduce the space between each game picture. Overall; an amazing job!
