#159269831 Make features section in homepage visible

[olusoladavid]

What does this PR do?

Makes the features section of the homepage visible to the user immediately after landing on the page. In the previous version, the hero section stretched to fill the height of the viewport thereby making the features section non-visible. This has been corrected to improve the user's experience on the landing page.

Description of Task to be completed

• Add the appropriate CSS classes
• Update the markup of the homepage (index.html)
• Ensure new change is responsive (displays well on smaller devices)

How should this be manually tested?

Review the changed files and see attached screenshots:
