Help Needed with story layout size

Hi guys,

I need help regarding the height and width of my project on storyline 2. Ive seen some templates here on the site which when completely span the entire webpage with no player borders.

Ive tried increasing the story size and unchecking all borders of the player including any sound/next buttons but I still see a border of the player.

I dont want to have the border visible, so that the project just looks like website and completely spans the webpage.
Can someone tell me the settings and dimensions to achieve that?
