Make 'Reputation' and 'Thanks' look like 'Posts'?

[iHatton]

Hello,

I want to make the 'Reputation' part and 'Thanks' part look like the 'Posts' part, so it is placed in a box and is neater.

Also, I want to move 'Reputation' down below 'Posts'.

How do I do this?

Here is an image for reference.

I have tried many methods, but one of them which may have worked says I need to edit 'Additional' under 'Main CSS', but I can't save it as it is 'obsolete'.

Thanks for any help.
