Put elements side by side (left -> right)

I am struggling to understand how to align my items from left to right.

In webdev its actually pretty simple, something like this:

I know the UI toolkit it similar but not the same, but still its a basic function. Hope someone can explain me why the same logic does not apply on unity.



Also, which styles exactly are all these symbols, is there a cheatsheet or something similar somewhere? It would be useful to see on hover which one it actually is, e.g.: wrap/nowrap etc. Right now if I hover over each symbol I see for example flex-wrap for each one of them.

 

Thanks for the help again. I had to override the styles of unity-content-container. I ignored it because it was greyed out, that on me.

For other people:

1. Create a new selector
2. Name it #unity-content-container and now you can apply styles on it
NOTE: If you have multiple scrollbars, it will affect all. In my case I wanted only one of my scrollbars to be affected.
For this you can add the parent to the selector, in my case: #Floors#unity-content-container
