From your computer, are you having an issue seeing the site in "Full Desktop View" (left) instead of "Zoomed View" (right) as shown below?
[Left hand side is correct Full Desktop View. Right hand side is a Zoomed View for smaller desktop monitors and some mobile devices.]

If you have difficulty seeing or reading items on the screen, you can use Accessibility preferences to magnify items on the screen. You can zoom the entire screen or zoom the area that has keyboard focus in a separate window.
Set up zoom
To zoom with keyboard shortcuts, select “Use keyboard shortcuts to zoom.”
To zoom with your mouse or trackpad, select “Use scroll gesture with modifier keys to zoom.”
To display it in a window near the mouse cursor, choose Picture-in-picture. To display it on the entire screen, choose Fullscreen.
You can also turn on zooming by pressing Command (⌘)-Option (⌥)-F5 and selecting options in the Zoom section.
To zoom in, press Command (⌘)-Option (⌥)-Equal Sign (=). To zoom out, press Command (⌘)-Option (⌥)-Minus Sign (-).
If you chose Picture-in-picture zooming, a window appears near the mouse cursor with the magnified image. If you chose the Fullscreen zooming, the entire screen displays the magnified image.
To zoom in and out, hold down the modifier key you specified while you perform the scroll gesture.
For example, if you have a trackpad and used the default settings, zoom in by holding down the Control (^) key while you drag two fingers up on the trackpad. Zoom out by holding down the Control key while you drag two fingers down on the trackpad.
If you chose Picture-in-picture zooming, a window appears near the mouse cursor with the magnified image. If you chose Fullscreen zooming, the entire screen displays the magnified image.
