[crimson3d]

Summary

Important bugs in mobile are fixed where the menu icon doesn't appear due to font-size pushing the container off-screen.

The structure of .app-marketing-grid is fixed where platform images overlap on tablets.

Changelog

• Enclose<h1>, <h2>, <h3>tags of the hero section within a .hero class to adapt font size for mobile devices.
• Eliminate offsets and replace them with display flex center + fix images that protrude beyond the column size.
• Some inline styles are removed and moved into CSS classes.
