min-height

Why do we need to give min-height: 100vh; to just set the flex-grow property as well, As i tried giving the flex-grow property it was not working any reasons behind that? 2) Flex-grow property goes only along Main Axis right?

The min-height is not needed to make flex-grow work, (though you do have to have some sort of height specified) but it is needed to make the footer "stick" to the bottom of the page. Without specifying the min-height as 100vh, the row still grows in relation to the other containers, but it doesn't grow enough to push the footer down. If you don't specify a height at all, then everything is going to be at its minimum height to fit the content. Once a height (or min-height) is specified, then if items need to grow to reach that height, the flex-grow property indicates the amount each element grows in relation to the others. And yes, flex-grow only applies to the main axis.
