Huddle landing page with single introductory section using Bootstrap

Any feebacks are welcome.

I have some doubts with the text position in different screen sizes, on larges screens the text must to be on the right side, and on smalls screens it must be centered, I used text-sm-right and text-xl-center, and the result was the opposite, even when I tried to change the right to the center, it doesn't work, and the same thing happened with the icons. Can someone help me with it?

For now, I think it is just this.
