Birth date without year

trying to eliminate the year from the birth date widget. i used the following css based on a tutorial:

#input_7_year,#sublabel_year {

    display : none !important;

}

you can see in the screen shot that it still leaves the drop down option and only eliminates the word "year". 

please help - this should be so much easier than it is.

The CSS code you are using is correct. However, the Field ID is incorrect.

Please, inject this code: 

#input_8_year,#sublabel_year {

    display : none !important;

}

Next time if you face something related to this, you can benefit from How to Find Field IDs guide. 

Thanks.

Thank you!
