Timer display even when scrolling through questions

Hello qualtrics community, I was wondering if anyone knew a Java Script code that would allow a timer to display at the top of the page of my survey? I know how to have a timer display to show how long someone has been on a survey, however the qualtrics function has the timer fixed at the top of the page. I would like the timer to be able to always display on the screen even if I scroll down to answer more questions on the survey. Is this possible? If so, would the code work for a particular block only or would it standardize it for the whole survey? My survey is broken into 8 parts, only 4 of those 8 blocks have survey questions on them and would only need a timer on those particular 4. Thank you, Kindly NM_Morales
