Formatting

This is more a CSS formatting question than anything related to the theme but hope someone can help.

I find that there is too much space wasted between container_24 and grid_24 and i would like to have the text in grid_24 closer to container_24. I have tried playing around with margins and padding and not found what I was looking for. Hoping someone can help. My site is https://www.mathurasri.com/

For those who are not familiar with the theme: container_24 is the blue background and grid_24 is where the text starts.
