Support Agency Landing page

This is a fully interactive website landing page I've created from StartupLanding Design templates in addition to many improvements over the original design to enhance user experience.

The website has many features including the following:

Users should be able to:

- View the nav link indicator for the currently active section in view

- view a fixed to the top navbar with a new state instead of the default

- View the optimal layout for the site depending on their device's screen size

- see an interactive and animated accordion

- See all features quality in a horizontal tabbed slider

- having a button to toggle monthly/annual pricing cards with flipping cards effect

- See all testimonials in a horizontal draggable/scrollable slider

- See hover states for all interactive elements on the page

- Receive an error message when the newsletter sign-up `form` is submitted if:

- The `input` field is empty

- The email address is not formatted correctly
