Critique my Product Landing Page

I Built This

Would love to hear criticism/suggestions on the design and especially if the whole site is properly responsive.

I think your site looks pretty good overall, great work! One small change that I would make is to bring the video away from the edge of the screen. Try these changes and tell me what you think:

From

.box-content {
margin: 3em 0;
}

to

.box-content {
  margin: 3em 3em;
}

and

#performance-desc {
  margin: 0 2%;
}

to

#performance-desc {
  margin-right: 1em;
}

This maintains your spacing between your content and embedded video.

You’re right that section looks cleaner now I like it, thanks for the input!

I would make the individual sections the same size vertically. The first section doesn’t fit on the page while the second and third sections do.
