Unable to see date entry

I have created a field date of birth.  When you populate this field you are unable to see more than 1 digit. the size of the field doesn't allow for more than one digit to be vuable.  

Please inject this custom CSS code to fix the issue:

#cid_77 {
max-width: 250px !important;
}

Here's a guide on How-to-Inject-Custom-CSS-Codes. Here's the result:

Hope that helps. Thank you.
