I am studying the default custom CSS code that exists in a new form and I had a question about the first section of the code.

On line 2 below, there are two .nf-filler-control-inner classes. Why?

/* Template styles */

.nf-form-input .nf-filler-control-inner, .nf-form-label .nf-filler-control-inner

{

top: 10px;

bottom: 10px;

left: 10px;

right: 10px;

}

Thanks
