I was tinkering with my page for a while and found out that there is a horizontal scorll bar!
Can anyone help me figure out I can get rid of this?

Take a look at .home-page-section-2 width:100vw. If I unset it in source the scrollbar goes away.
I got it! Thanks a bunch, @webdev !! 
But I have to know if you don’t mind explaining, why did this happen? I assumed that by setting the width to 100vw, I can set the length of the section to that of the computer screen.
Take a look at this relevant stackoverflow (I don’t like to repeat myself) →
