i have a work book open with information in columns b-j and rows 1-ongoing

i left colum a blank. what i need to happen is that , when data is entered into any of the cells in column A, the row associated with where the information was enetred, needs to be highlight yellow. I know you can simply manually do this however would like the colour to autmoatically highlight the ROW when data is enetered in column A.
for example if i entered anything into cell A1, the entire row 1 will highlight a color
Thanks in advance, im sure this is something very basic too
