Auto Format Fill Colour Background On Certain Cells

I have been working on a spreadsheet but I use autoformat for.

For example if the date in the cell matches today's date then it turns the text read and makes it bold.

I was wondering if there was a way to format several cells in a row if a certain criteria was met.

for example

A B C
1 Item Cost Quantity
2 Car £11,520 2
3 Bike £7,500 1
4 Tyres £50 4

Now for example if I set a condition whereas the quatity is greater than 3 then it would highlight the whole row.

So in the example above I would like to to highlight row 4 and Fill colour cells A4,B4 & C4 with a yellow background and Red Text and make the texted bold.
