Hi, I need a quicker way to compare a range of columns using conditional formatting

I want to compare A2 & A1, B2 & B1, C2 & C1, D2 & D1, E2 & E1.

How I do is one at a time.

Example: Starting with cell B3, I use the rules "=B3<>A3" with the range "=$B$3:$B$12".

Then i will repeat for cell D3, then F3, then H3 then finally J3.

Instead of doing them one at a time, is there a quicker way to do this?

Thanks

I have attached a file for your reference. I did cell B3 as a sample.

Thanks
