Conditional cell formatting

Question

Is it possible to autoformat spreadsheet like this

IF A1 = C1 then A1:E1 background should become light gray

Answer 1

Ok I know how to do it, if anyone cares, you do like @Eric Fortis but:

1. formula should be =$A1=$A3
2. applies to range =$A1
3. copy cell A1
4. select area where you want to do formatting
5. home tab, click on paste dropdown menu
6. choose special paste
7. choose only pasting formats
