I have used the video below to insert the video banner in the image banner on Dawn Theme and changed all necessary codes to remove the grey line underneath the video.
I would although like to make the video bigger. When I change any rem’s in the following codes that I have added (see pic 1), the grey line seems to appear again and I am unsure on how to change the rest of the information in the codes to make it disappear again.
