Command plus is no longer working for me correctly in Safari 8.0.2.

Question

Command plus is no longer working for me correctly in Safari 8.0.2.  When I use it to zoom in a safari window, it makes fonts bigger instead of scaling the entire page bigger like it used to.  What changed or what did I accidentally change?   This  is only happening in Safari.  When I use Command Plus in a Chrome or firefox browser window, it works perfectly still.
To explain this a little better,  I have a 27" iMac.  When I open a browser widow in safari like yahoo.com,  The content fits in about a 10.5" section of the screen.  If i go to full screen or enlarge the window to fit the full screen the same 10.5" content is centered in my screen.  Previously, I could use Command Plus to zoom and the entire page would scale increasing from 10.5" to eventually filling the screen.  Now when I use command plus, the font's get bigger and bigger but the page width stays at 10.5"

Hi petraidm,
Welcome to the Support Communities!  If I'm understanding you correctly, it appears you have updated Safari to the latest version, but are still using Mountain Lion as your operating system, is that correct?
You may need to adjust your screen resolution, or the zoom settings in the Accessibility pane of System preferences.   Usually, zooming changes the size of text or content in a window -- not the size of the window itself.   So I usually go to full screen mode in Safari, and then zoom in if I need to enlarge the text.

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
Choose Apple menu > System Preferences, click Accessibility, and then click Zoom.
Do either of the following:
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.”
Choose where the magnified content appears with the Zoom Style pop-up menu.To display it in a window near the mouse cursor, choose Picture-in-picture. To display it on the entire screen, choose Fullscreen.
To set options for zoom or the zoom window, click More Options.More Options panel
You can also turn on zooming by pressing Command (⌘)-Option (⌥)-F5 and selecting options in the Zoom section.
Zoom with keyboard shortcuts
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.
Zoom with a mouse or trackpad
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.
