When I first got InDesign, things would auto-center with a green or pink line depending on what I was trying to align. Lately this isn't appearing at all.
I could also see the spacing between different boxes and see if they were aligned. How can I turn this option back on?
I'm currently running InDesign CC.
The feature you describe is called Smart Guides. It sounds like you've somehow disabled them.
To show or hide Smart Guides:
If that doesn't work, the Smart Guide Options in the preferences might have been disabled.
To control which Smart Guide Options are enabled:
Also although Smart Guides will display when you are 'previewing' your document, they are easiest to work with when the Screen Mode you're working in is set to Normal. (View > Screen Mode > Normal), and when not working in Overprint Preview (View > Overprint Preview).
Hope this helps.
I read your advice and the Smart Guides was greyed out and unavailable to click.
It turns out Smart Guides was disabled because I somehow turned on the "Snap to document grid." I found the solution here.
Thank you for helping me figure out what the actual Smart Guides were called!
