List design - 4 Users in one row

As I promise: Next question coming up very soon! (sorry for that)

Okay. In the lists I want to show the user details in one colum. (name,picture)
But I want 4 users in one row, not one row for each user.

Is that possible?

4 users in 1 row? Not possible. Each user is a database table row. If you mean you want a bottom border or something styled after the 4th row instead of each then you'd need to consult with your template developer. The example below would do the trick, but I've no idea if you have other CSS present that'd conflict.

Please note the above is a CSS3 selector and only works on modern browsers (IE8, IE9, Chrome, FF, etc..).

No, I mean 4 user in one row.
I mean to make a colum from a user instead of a row.
But you say it´s not possible. Thats very said.
If you make a list with no other information than the picture you got a very said and empty page.
Thats why I ask.
Maybe changing the design of the list is a nice idea for a plugin

Well it's not possible depending on what you're wanting. I don't understand your request fully. If you have 4 columns and each column has fields then of course not, but if you want 4 users displayed across 4 columns (1 column per user) then I guess it can be done. Could you provide a screenshot, picture, or something of what you're wanting so visually can understand your needs. In nearly all cases all visual changes can be done with CSS avoiding core edits or new development.
