Quick overview:
Configure the viewport
Your page specifies a fixed-width desktop viewport. Use a responsive viewport to allow your page to render properly on all devices.
Configuring a viewport specifying width=device-width instead of width=750 will allow your page to adapt for devices of various widths. This may require additional work to adapt your styling for smaller screens.
