Is there any way to reduce the space in the Player for Storyline

Hello Shilpa, 

Thanks for reaching out! 

If you match the slide size of your project file with the resolution of your monitor, you'll see the slide take up more space in the player. This is because the course's player automatically adjusts how the course is presented to learners depending on the screen resolution of the monitor.
