Testimonial Grid Section

Hey Naman! Your project looks great! To solve your centering issue, one thing you could try using flexbox on the '.container' class.

display: flex;
align-items: center;
justify-content: center;

'align-items' should center the grid vertically and 'justify-content' should center the grid horizontally. You would probably have to remove any margin/padding that you have on the '.container' and '.mainbox' classes and perhaps set the 'height' or 'min-height' of the '.container' class to '100vh' to ensure it centers the grid relative to the height of the screen rather than the height of its parent element.

Hope this helps!

To center a grid, you can just do

place-items: center;

I would also suggest you giving the body a little padding at the bottom.
