Sub Label Empty Space

I removed the sub-label text from some fields (Name & Phone specifically) but still have "empty" space where the text previously appeared.  How can I remove this space?  Thank you!

Please inject the following code to Custom CSS to hide the sub labels of First Name, Last Name, Area and Phone number.

#sublabel_first, #sublabel_last,

#sublabel_area, #sublabel_phone {

display: none;

}

Please get back to us if you need further assistance. Thank you.

Thanks for your reply Kiran but unfortunately that didn't work...  The label classes appear to be "form-sub-label" for both the name and phone fields.  The direct "for" references are as follows:

First & Last Name Sub Labels
for="first_22"
for="last_22" 

Area Code & Phone Number Sub Labels
for="input_21_area"
for="input_21_phone" 

Would the code I inject into the CSS need to be modified to reflect the names or what am I doing wrong?  Thanks!

Solved, Thanks!
