using check box and issue with other

i am using the check box and when i allow for other the box does not align with check box but bellow it how do you get it to align to the check box, see attached

The width of the Checkbox added to the  Textbox is a bit larger than the container, causing it to jump to above. Inject bellow CSS code into form.

.form-radio-other-input,

.form-checkbox-other-input{

    width:100px;

} 

It should align both Textbox and Checkbox.

Thanks!
